Safety Clamp Parts for Tubing Running, Drill Collar Handling & Well Servicing

SGPE supplies Safety Clamp Parts for the maintenance and repair of Type T (WA-T), Type C (WA-C), Type C-XL (CXL) and MP safety clamps used in oil and gas drilling, drill collar handling, tubing running, well completion and workover. These tools support approved tubular-handling procedures on land rigs, offshore drilling units and well-service equipment.

Our oilfield safety clamp replacement parts include gripping inserts, MP gripping dies, die carriers, complete link assemblies, link pins, springs and mechanical closing components. Repeated pipe contact, drilling fluids and harsh operating conditions can wear gripping teeth, loosen joints and damage moving parts. Timely inspection and proper replacement help maintain the clamp’s intended performance.

Selecting the right spare part requires more than matching the pipe diameter. Insert profiles, link geometry, carrier dimensions and retaining arrangements vary between clamp designs. SGPE can review original part numbers, technical drawings and component photographs to help identify suitable replacements, including parts for older equipment. The model charts and component references below provide useful guidance for maintenance planning and spare-parts procurement.

Safety Clamp Replacement Components

The main Safety Clamp Replacement Parts fall into three groups: gripping components, articulated link assemblies and mechanical closing hardware. Each group performs a different function, and component designs vary across Type T, Type C and MP safety clamps.

Gripping Inserts, Dies and Carriers

Type T and Type C Safety Clamp Inserts use spring-loaded gripping arrangements to engage compatible tubular surfaces. In contrast, MP Safety Clamp Gripping Dies fit into separate die carriers within the articulated clamp assembly.

Depending on the original design, maintenance teams may need individual gripping inserts, replacement MP dies, empty die carriers or complete carrier assemblies with dies installed. These components differ in tooth profiles, backing geometry, seating surfaces and retaining arrangements.

The correct gripping element must fit its corresponding mounting system. Similar-looking inserts and dies from different clamp families should not be treated as interchangeable.

Complete Link Assemblies, Hinged Links and Link Pins

Safety Clamp Link Assemblies form the articulated body that wraps around the tubular. Intermediate links connect adjacent sections, while screw-end, pivot-end and latch links serve specific positions within the closing arrangement.

Link pins connect the individual sections and allow the clamp to open, close and conform to its intended operating diameter. The number and arrangement of links depend on the original clamp configuration.

Replacement options may include individual hinged links, matching pins or complete link assemblies. Proper identification requires attention to link geometry, pin-bore dimensions, connection spacing and the design of adjacent components.

Clamp Screws, Nuts, Springs and Retaining Hardware

Safety Clamp Screws, Nuts and Pivot Components form the mechanical tightening system. Depending on the clamp design, the assembly may also incorporate pivot blocks, bushings, thrust washers and other connecting hardware.

Standard single-screw arrangements differ from the Type C-XL double-screw closing system, which requires model-specific tightening components.

Insert springs, carrier springs, cotter pins, keeper pins and retaining hardware support the positioning and retention of gripping elements and articulated connections. Although these components are relatively small, their dimensions and installation arrangements are important to the overall assembly.

Replacement hardware should match the original component specifications and corresponding mating parts.

Safety Clamp Models and Pipe OD Reference

The ranges below identify selected complete-clamp configurations, not universal gripping or spare-part dimensions. Actual compatibility depends on the manufacturer’s approved model and assembly revision.

7624-A-4 is an industry reference for a Type C insert with cotter. WPI Wellkin lists 12-103, and Keystone Energy Tools lists A12-103. Inspect the insert seat, spring and link-pin bores as well as the replacement teeth.

WA-C clamps support selected drill collar connection makeup and breakout, BHA preparation, offshore drilling and rig-floor tubular-handling procedures.

Type C-XL (CXL) Safety Clamp Parts – Double-Screw Models

Larger Type C-XL safety clamps use a double-screw closing system. They should not be confused with MP-XL clamps or standard single-screw WA-C assemblies.

Type CXL Model and Industry Assembly References

Configuration	Pipe OD Range (in)	Links	Industry Assembly Reference
CXL	15-1/2–17	18	7624-5084
CXL	16-1/2–18	19	7624-5085
CXL	17-1/2–19	20	7624-5086
CXL	18-1/2–20	21	7624-5087

Replacement requests may involve larger links, gripping inserts, pivot components and double-screw closing hardware. Supply the original assembly number and photographs of the closing system to identify the correct configuration.

MP Safety Clamp Parts – MP-S, MP-R, MP-M, MP-L and MP-XL

Multipurpose (MP) Safety Clamp Parts include gripping dies, carriers, complete links, springs, latch hardware, screws and retaining pins. MP designs hold the gripping dies in carriers rather than using the same insert mounting arrangement as common Type T and Type C clamps.

The number of gripping dies varies with the complete MP assembly. Use the model and assembly reference to identify the required die set.

MP Reference Differences: 2714, 3303 and 51405-10

WPI Wellkin identifies 2714 as a thrust washer and 3303 as a nut. Keystone Energy Tools lists 2714 as a screw nut and 3303 as a thrust washer. Published descriptions of 51405-10 also differ between link-pin and screw-pin cotter references. Match these components to the original drawing and revision, not the reference number alone.

A catalog-listed lifting eye (3317) does not turn a standard non-hoisting safety clamp into an approved lifting device.

MP-S Gripping Dies 3333 vs. MP Dies 3310

Replacement Component	MP-S Reference	Selected Non-MP-S Reference
Gripping Die	3333	3310
Carrier Assembly with Die	3325	3324
Complete Link Assembly	3335	3319

3333 and 3325 are common MP-S gripping die and die-carrier references; 3310 and 3324 appear for selected non-MP-S configurations. Their backing geometry and retaining features may differ, so the die, carrier and supporting link must be checked together.

For a complete MP safety clamp die set, confirm the die count in the assembly table and the original die/carrier design. A link count or pipe OD alone is insufficient.

Safety Clamp OEM Part Number Cross-Reference and Repair Kits

Maintenance teams often know an old part number but not the clamp manufacturer or revision. SGPE reviews safety clamp aftermarket replacement enquiries using the complete assembly details, dimensional drawings and original components.

What to Check Before Ordering

Component	Information Needed
Gripping Insert or Die	Original reference, dimensions, tooth profile and backing geometry
Die Carrier	Model, dimensions, die mounting and spring arrangement
Complete Link Assembly	Link geometry, pin bores, center distances and retaining features
Link Pin	Diameter, length, head design and retaining method
Clamp Screw or Nut	Thread dimensions, length and mating components
Repair Kit	Complete clamp model, link configuration and required quantities

For an unmarked clamp, a photograph of the complete assembly and close-ups of the damaged part, pin bores, threads and retaining features are often more useful than a pipe-size estimate.

Safety Clamp Repair Kits by Clamp Family

Clamp Family	Common Maintenance Components
Type T / WA-T	Gripping inserts, insert springs, link pins, cotters and closing hardware
Type C / WA-C	Gripping inserts, springs, link assemblies, pins and pivot components
Type C-XL	Gripping components, links and model-specific double-screw parts
MP-S to MP-XL	Gripping dies, die carriers, carrier springs, links, pins and latch components

Customers can enquire about individual inserts, complete link assemblies, matched gripping sets or model-specific safety clamp repair kits. Define the parts and quantities in the kit; there is no universal kit suitable for every clamp.

Safety Clamp Inserts vs. Rotary Slip Inserts and Tong Dies

Safety clamp inserts, rotary slip inserts, drill collar slip dies and manual tong dies serve different tools. Even when their gripping teeth look similar, mounting dimensions and operating functions may differ. They should not be treated as universal replacements.

Oilfield Applications

Drill Collar Handling and BHA Assembly

Type C and MP safety clamps provide secondary anti-slip restraint during selected drill collar makeup and breakout, drill-string assembly and bottom hole assembly (BHA) preparation. These operations involve repeated pipe contact and clamp adjustment, which can gradually wear gripping surfaces, hinge joints and closing components.

Replacement gripping inserts, MP gripping dies, link pins and complete link assemblies help drilling crews maintain existing clamps used in conventional, directional and deep-well drilling programs. Maintenance teams can inspect these components between drilling operations and replace worn parts according to the original equipment requirements.

Tubing Running, Completion and Workover

Type T safety clamps support selected production tubing running and pulling, flush-joint tubing handling, well completion, recompletion and oilfield workover procedures.

Frequent opening, closing and tubular contact can wear gripping inserts, springs and mechanical tightening components. Workover rigs, pulling units and well-service crews may therefore require replacement parts during tubing replacement, production well maintenance and other approved intervention activities.

Keeping model-specific tubing safety clamp spare parts available can help maintenance teams address worn components and prepare equipment for subsequent well-servicing operations.

Land Rigs, Offshore Units and Maintenance Workshops

Mechanical safety clamps serve tubular-handling operations on land drilling rigs, offshore platforms, jack-up rigs, semi-submersibles and drillships. Offshore exposure to saltwater, humidity and drilling fluids can accelerate corrosion, while repeated rig-floor handling places additional wear on gripping elements and moving joints.

Replacement safety clamp inserts, die carriers, springs, link assemblies and closing hardware support planned maintenance across these operating environments.

Oilfield equipment workshops also service clamps returning from drilling and workover projects. For older equipment with damaged or unreadable nameplates, original component dimensions and assembly details can help identify suitable replacement parts before the clamp returns to service.

Safety Clamp Inspection and Replacement

Inspect safety clamps according to the original equipment manufacturer’s maintenance instructions. When a component fails inspection, examine its mating parts before choosing a repair.

Common Inspection Findings

Inspection Finding	Recommended Action
Broken or worn gripping teeth	Inspect and replace unsuitable inserts or dies
Damaged insert or carrier springs	Replace with matching springs
Worn die carriers	Inspect and replace defective carrier assemblies
Missing retaining hardware	Install the specified cotters or pins
Excessive link pin wear	Check pins and corresponding link bores
Cracked or distorted links	Remove the clamp from service for qualified assessment
Damaged screw threads	Inspect and replace unsuitable closing components
Incomplete clamp closure	Check screws, nuts, pivots and latch components
Excessive corrosion	Assess affected components against the manufacturer’s criteria

Do not weld, straighten or modify damaged links without the original manufacturer’s approval. Qualified personnel should inspect the repaired assembly before it returns to service.

Safety notice: Standard non-hoisting safety clamps provide secondary anti-slip restraint. They do not replace elevators, rotary slips, spiders or other approved primary load-support equipment.

Safety Clamp Materials, Inspection Documents and API Spec 7K

Link assemblies, gripping dies, springs and closing hardware do not share one universal material grade or hardness. Their properties and dimensions must match the original component specification.

SGPE can review requests for dimensional inspection, material certificates, hardness records, traceability and certificates of conformity. Document availability depends on the confirmed component and order scope.

API Spec 7K addresses drilling and well-servicing equipment, including safety clamps not used for hoisting. This does not mean every aftermarket component is independently API certified. Any API Monogram or product-certification claim must be supported by records for that specific item.

Safety Clamp Parts Supplier, Pricing and RFQ

Most oilfield safety clamp spare parts require a model-specific quotation. Price and lead time depend on the component design, material, quantity, inspection scope and delivery destination. A loose gripping die, a complete carrier assembly and a hinged link are different procurement items.

For an efficient RFQ, send the information available in the table below. The original part number or a clear photograph is often enough to begin a technical review.

These tool families have different mounting arrangements. A similarly named insert is not necessarily interchangeable.

Frequently Asked Questions About Safety Clamp Parts

1. What Are Safety Clamp Parts Used for in Oil and Gas Drilling and Workover?

Safety Clamp Parts are replacement components used to maintain and repair mechanical safety clamps during oil and gas drilling, drill collar handling, well completion and workover operations. Common components include gripping inserts, gripping dies, die carriers, link assemblies, pins, springs and closing hardware.

Type T, Type C and MP safety clamps provide secondary anti-slip restraint for compatible smooth-body tubulars during approved handling procedures. They support operations such as production tubing running, drill collar connection handling and bottom hole assembly (BHA) preparation. However, standard non-hoisting safety clamps do not replace elevators, slips or other primary tubular-support equipment.

2. Which Replacement Parts Are Available for Type T (WA-T) and Type C (WA-C) Safety Clamps?

Common Type T and Type C Safety Clamp Replacement Parts include gripping inserts, insert springs, complete link assemblies, intermediate links, link pins, clamp screws, nuts and pivot components.

Type T (WA-T) clamps typically support smaller-diameter production tubing and flush-joint pipe handling during well completion, tubing running and workover. Type C (WA-C) clamps serve selected drill collar handling, connection makeup and breakout, and BHA assembly operations on land and offshore drilling rigs.

Industry references include 7624-A-21 for Type T gripping inserts and 7624-A-4 for Type C gripping inserts. The replacement must match the original clamp design, component dimensions and retaining arrangement.

3. What Spare Parts Are Available for MP-S, MP-R, MP-M, MP-L and MP-XL Safety Clamps?

MP Safety Clamp Parts include gripping dies, die carriers, complete carrier assemblies, carrier springs, hinged links, link pins, latch components and mechanical closing hardware.

These components support multipurpose safety clamps used for drill collars, flush-joint pipe and compatible smooth-body tubulars during drilling, offshore operations and selected workover procedures.

Common industry references include 3333 for MP-S gripping dies, 3310 for selected larger MP gripping dies, and 3325 and 3324 for corresponding carrier assemblies with dies. Because MP models use different link and gripping arrangements, replacement selection must follow the original clamp configuration. MP-XL components should not be confused with Type C-XL double-screw clamp parts.

4. What Pipe Sizes Do Type T, Type C, Type C-XL and MP Safety Clamps Cover?

Common Type T (WA-T) Safety Clamps cover selected pipe outside diameters from 1-1/8 to 4-1/2 in, while standard Type C (WA-C) Safety Clamps cover 3-3/4 to 15-5/8 in. Selected Type C-XL configurations extend to larger tubular diameters of approximately 15-1/2 to 20 in.

The MP-S, MP-R, MP-M, MP-L and MP-XL families cover selected pipe sizes from 2-7/8 to 30-1/2 in, depending on the assembly. These ranges may overlap or contain gaps.

The published sizes describe complete safety clamps, not universal replacement-part dimensions. Buyers should confirm the original model, link configuration and approved gripping range before ordering.

5. What Are the Cross-Reference Part Numbers for Type T and Type C Gripping Inserts?

Common industry references for Type T Safety Clamp Gripping Inserts include 7624-A-21, 11-103 and A11-103. WPI Wellkin lists 11-103 as a cross-reference for the Type T insert, while Keystone Energy Tools uses A11-103 in its catalog.

For Type C Safety Clamp Gripping Inserts, published references include 7624-A-4, 12-103 and A12-103, with the latter two appearing in the respective manufacturers’ catalogs.

These numbers help maintenance teams and oilfield spare-parts buyers identify replacement requirements. However, an industry cross-reference does not guarantee interchangeability. The insert’s tooth profile, backing geometry, dimensions and retaining features must match the existing clamp.

6. Can MP-S Gripping Die 3333 Replace MP Safety Clamp Gripping Die 3310?

MP-S Gripping Die 3333 and MP Gripping Die 3310 are not universally interchangeable. Published industry catalogs commonly associate 3333 with MP-S safety clamps, while 3310 appears in selected larger MP configurations.

The corresponding carrier assemblies also use different references. MP-S commonly uses Carrier Assembly 3325, while selected non-MP-S models use Carrier Assembly 3324.

Differences in backing geometry, mounting surfaces and retaining features may prevent one die from fitting another model. During drill collar handling or offshore rig maintenance, technicians should verify the gripping die, carrier and supporting link assembly together before installing replacement components.

7. How Many Gripping Dies Are Required for a Complete MP Safety Clamp Replacement Set?

The number of MP Safety Clamp Gripping Dies depends on the complete clamp model, pipe outside diameter and link configuration.

Published industry assemblies include 8 gripping dies for MP-S 33030 and 29 gripping dies for MP-XL 33039, with other configurations requiring different quantities. For example, larger MP-R, MP-M and MP-L clamps use progressively different link and die arrangements according to their assembly references.

When ordering a complete replacement die set for drilling or workover equipment, buyers should confirm the original model, assembly number and die-carrier design. Pipe diameter alone cannot determine the correct quantity or ensure that the replacement gripping elements will fit.

8. Can I Order Individual Safety Clamp Replacement Parts or Complete Repair Kits from SGPE?

SGPE handles enquiries for individual Safety Clamp Replacement Parts, complete link assemblies, die carrier assemblies, matched gripping sets and model-specific Safety Clamp Repair Kits.

For routine maintenance, drilling contractors may need only worn gripping inserts, carrier springs, link pins or retaining hardware. More extensive repairs may require complete link assemblies, replacement die carriers or selected closing components.

These requirements arise during planned maintenance on land drilling rigs, offshore platforms, workover rigs and oilfield service equipment.

The contents of a repair kit depend on the original clamp design and approved maintenance requirements. SGPE can review the requested parts and quantities to establish an appropriate supply scope.

9. Can SGPE Help Identify Obsolete, Unmarked or Older Safety Clamp Parts?

SGPE can assist with Safety Clamp OEM Part Number Cross-Reference enquiries and the identification of possible aftermarket replacement parts for older Type T, Type C and MP safety clamps.

Some existing clamps have missing nameplates, unreadable part numbers or outdated equipment documentation. In these cases, photographs of the complete clamp and damaged component can help establish the original design.

Technical drawings, measured dimensions, pipe OD, link count and information about the closing mechanism also support replacement identification.

This service is particularly useful for oilfield maintenance workshops, drilling contractors and workover service companies repairing older equipment. Any proposed replacement still requires dimensional and technical compatibility confirmation.

10. When Should Safety Clamp Gripping Inserts, Link Pins and Other Components Be Replaced?

Safety Clamp Gripping Inserts, Dies, Links and Pins should be inspected and replaced according to the original manufacturer’s maintenance instructions and acceptance criteria.

Common warning signs include worn or broken gripping teeth, damaged springs, excessive clearance around link pins, cracked or distorted links, corrosion and defective clamp screw threads.

Regular inspection is especially important for equipment exposed to drilling mud, moisture, offshore saltwater and repeated tubular-handling operations.

If damage affects the clamp’s structural integrity or gripping arrangement, the equipment should be removed from service for qualified assessment. Maintenance personnel should examine mating parts before completing repairs and returning the clamp to operation.

11. Do Safety Clamp Replacement Parts Meet API Spec 7K Requirements?

API Spec 7K addresses drilling and well-servicing equipment, including safety clamps that are not used as hoisting devices. However, this equipment classification does not automatically mean that every individual replacement insert, gripping die, link assembly or aftermarket component has independent API certification.

Applicable requirements depend on the original equipment design, the specific replacement part and the purchase specification.

For drilling contractors and offshore projects that require material traceability, dimensional inspection reports, hardness records or certificates of conformity, these requirements should be included in the procurement enquiry.

SGPE can review the requested inspection and documentation scope when preparing a quotation. Any API certification claim must be supported by records for the specific product.
