Description
Casing Slips for Oilfield Rotary Table Casing Running and Rig-Floor Support
SGPE Casing Slips are mechanical oilfield tubular-handling tools that grip and temporarily support casing strings during oil and gas drilling, casing running, well construction and selected casing-related workover operations.
During casing installation, the rig hoisting system lifts and lowers the tubular string. Meanwhile, correctly matched casing slips hold it stationary while crews prepare threaded connections and transfer loads.
A conventional casing slip assembly uses segmented gripping bodies, replaceable inserts and matching tapered support surfaces. The inserts engage the casing outside diameter (OD), while a compatible rotary table insert bowl, casing bushing or chuck and lining transfers the suspended load into the designated support structure.
This mechanical arrangement helps crews maintain stationary casing support during approved rig-floor operations. However, proper performance depends on the casing dimensions, gripping components, taper geometry and load capacity.
SGPE supplies two main product families. CMS Type Casing Slips cover selected casing sizes from 4-1/2 to 30 in (114.3–762 mm). They use segmented, heat-treated alloy-steel bodies with replaceable gripping components.
For medium and large-diameter casing programs, UC-3 Casing Slips cover selected sizes from 7 to 42 in (177.8–1,066.8 mm). The UC-3 series uses multi-piece gripping bodies with matching chucks and linings. SGPE publishes a rated capacity of 250 US short tons for its listed UC-3 configurations.
SGPE manufactures these products according to API Spec 7K requirements. Suitable configurations support casing running on land drilling rigs, offshore platforms, jack-up rigs, semi-submersibles, drillships and compatible oilfield workover equipment.
In addition to complete slip assemblies, SGPE supports enquiries for replacement gripping inserts, spare parts and dimensional cross-reference requirements.

SGPE Casing Slips Models and Technical Overview
Choosing the correct oilfield casing slips starts with the casing string and its supporting equipment.
The slip assembly must match the pipe body, while the bowl, bushing or chuck must provide the correct tapered seating interface. The complete support system must also meet the approved load requirements.
Although CMS and UC-3 configurations overlap in several casing sizes, they use different gripping structures and support arrangements.

The table summarizes SGPE’s two product families. Each diameter requires the correct assembly rather than a universal adjustable slip set.
The 250 US short ton capacity applies to the published UC-3 configurations. Buyers must confirm CMS rated capacities separately and verify the entire load-bearing system.
CMS Type Casing Slips – Conventional Rotary Table Casing Support
SGPE CMS Type Casing Slips support selected casing outside diameters from 4-1/2 to 30 in (114.3–762 mm).
The CMS design uses multiple gripping segments around the casing body. Each segment contributes to the assembly’s circumferential contact, while replaceable inserts engage the pipe surface.
SGPE uses heat-treated alloy steel for the CMS slip bodies. These structural components support repeated handling during drilling and casing-running operations.
The assembly works with its designated rotary table insert bowl or casing bushing. When crews transfer the casing load onto the slips, the matching tapered surfaces help generate the inward gripping force.
CMS configurations differ in weight, segment quantity and supporting equipment. For example, the 9-5/8 in CMS Casing Slips configuration uses 14 segments, while the 13-3/8 in CMS configuration uses 18 segments.
Replaceable gripping components also allow maintenance personnel to renew worn contact parts according to the manufacturer’s instructions.
These characteristics make CMS Type Casing Slips suitable for conventional casing-running programs that use compatible rig-floor support systems.

CMS Technical Notes and Insert Bowl Compatibility
The published weight values describe individual CMS configurations. They do not represent the shipping weight of every order. Final packed weights depend on the selected assembly and packing scope.
The bowl references identify the support-equipment designations in SGPE’s published specifications. However, the exact mating geometry requires confirmation against the approved technical drawing.
For example, the table lists a No. 2 insert bowl reference for 9-5/8 in CMS Casing Slips and a No. 1 reference for 13-3/8 in configurations.
Larger CMS assemblies require matching casing bushings.
The term API in the bowl column follows the published support-equipment designation. It does not indicate API Monogram certification.
Before ordering, buyers should confirm the casing OD, selected CMS model, approved capacity, insert bowl designation, taper and seating dimensions.
A matching casing diameter alone does not establish interchangeability with another manufacturer’s rotary table insert bowl.
UC-3 Casing Slips – 250 Ton Heavy-Duty Casing Support
SGPE UC-3 Casing Slips cover selected casing outside diameters from 7 to 42 in (177.8–1,066.8 mm).
The UC-3 series uses multiple slip bodies with matching gripping inserts. These components surround the casing and provide contact around its circumference.
Each configuration works with its designated chuck and lining. The tapered support interface transfers the casing load into the approved rig-floor structure.
SGPE publishes a 250 US short ton rated capacity for the listed UC-3 configurations.
The series includes two published back-cone taper arrangements. The 7, 7-5/8 and 8-5/8 in configurations use a 1:3 taper, while the other listed configurations from 9 to 42 in use a 1:4 taper.
This distinction matters when buyers replace existing oilfield casing slips. Even when two models cover similar casing sizes, they may require different chucks, linings or slip body specifications.
UC-3 Casing Slips – Full Technical Specifications

Published UC-3 Rated Capacity: 250 US short tons for the listed configurations.
UC-3 Technical Notes and Chuck Compatibility
The slip body specifications follow SGPE’s published technical data.
For larger sizes, the designation Same as 13-3/8 in reproduces the manufacturer’s body specification reference. It does not establish the complete external dimensions of the assembly.
The number of segments and inserts changes according to casing diameter. Therefore, maintenance teams should use the correct model specifications when ordering replacement components.
The chuck and lining must also match the designated taper. A 1:3 configuration cannot automatically replace a 1:4 assembly.
Most importantly, the complete support arrangement must meet the applicable load requirements. The published slip rating alone does not establish the capacity of every associated support component.

Common Casing Slips Sizes and Model Selection
Drilling contractors often search for casing slips by the actual casing outside diameter rather than by a general product name.
Typical procurement enquiries include 7 in Casing Slips, 9-5/8 in Casing Slips, 10-3/4 in Casing Slips, 13-3/8 in Casing Slips, 20 in Casing Slips and 30 in Casing Slips.
SGPE offers several of these diameters in both CMS and UC-3 configurations. However, the two families use different gripping structures and support interfaces.
7 in and 9-5/8 in Casing Slips
For 7 in casing, the published CMS configuration uses 12 segments. The UC-3 configuration uses 10 segments and a 1:3 taper.
For 9-5/8 in casing, the CMS assembly uses 14 segments and a No. 2 bowl reference. The UC-3 version uses 10 segments, 10 inserts and a 1:4 taper.
These models can support selected production and intermediate casing-running programs when the complete equipment arrangement meets the project requirements.
10-3/4 in and 13-3/8 in Casing Slips
SGPE offers 10-3/4 in Casing Slips in both product families. The CMS configuration uses 15 segments, while the UC-3 version uses 10 segments and a 1:4 taper.
For 13-3/8 in casing, CMS uses 18 segments with a No. 1 bowl reference. Meanwhile, UC-3 uses 12 segments, 12 inserts and a 1:4 taper.
These sizes frequently appear in intermediate and surface casing equipment enquiries.
20 in, 24 in and 30 in Casing Slips
Large-diameter well construction may require 20 in, 24 in or 30 in Casing Slips.
SGPE lists these sizes in both CMS and UC-3 product ranges. UC-3 configurations also extend to 36 in and 42 in casing.
These options may suit selected surface casing, conductor casing and other large-diameter casing programs.
However, the contractor must confirm the casing wall thickness, maximum suspended load, available rig-floor space and support-system capacity before choosing the equipment.
The published size range does not guarantee suitability for every conductor casing installation.
How Rotary Table Casing Slips Work
Conventional Rotary Table Casing Slips, also called mechanical or manual casing slips in some oilfield equipment enquiries, use a wedge-type gripping principle.
The gripping segments surround the casing body and fit into a matching tapered support arrangement.
When drilling crews transfer the suspended load onto the slips, the tapered surfaces generate inward gripping force. The inserts engage the pipe body, while the supporting bowl or chuck transfers the load to the rig-floor structure.
The slips hold the casing stationary while the crew prepares or handles a connection. Once the hoisting equipment takes the load again, the crew releases the slips according to the manufacturer’s instructions.
The casing OD, gripping-tooth condition, taper geometry, pipe grade, wall thickness and suspended load all influence the suitability of the gripping arrangement.
Although segmented contact can distribute gripping force around the casing circumference, it does not eliminate the possibility of slip marks or localized casing deformation.
Operators must follow the equipment instructions and approved casing-running procedures.
Casing Slips Applications in Oil and Gas Drilling
SGPE casing slips support stationary casing handling during onshore drilling, offshore drilling, casing running, well construction and selected oilfield workover operations.
The actual application depends on the rig’s support equipment, casing specifications and approved operating procedures.
Onshore Drilling and Conventional Casing Running
Land drilling rigs use casing slips when crews need stationary support during casing installation.
The slips work alongside casing elevators, manual or power casing tongs and compatible rig-floor support equipment. Together, these tools support connection handling and controlled load transfers.
Appropriate configurations may also serve top-drive drilling rigs equipped with compatible rotary table casing support systems.
Surface and Intermediate Casing Installation
Surface casing provides structural support during well construction, while intermediate casing helps isolate selected formations and supports later drilling stages.
During these operations, the crew repeatedly connects and lowers casing joints. Casing slips provide stationary support during approved connection-handling stages.
Common equipment enquiries include 9-5/8 in, 10-3/4 in and 13-3/8 in Casing Slips.
For deeper wells, engineers should pay particular attention to suspended load, casing wall thickness and the complete support-system rating.
Production Casing Running and Well Completion Support
Production casing installation requires careful control of the pipe body and threaded connections.
Matched casing slips support the string during applicable connection-handling operations.
Casing grade and wall thickness influence the pipe’s response to external gripping pressure. In addition, corrosion-resistant alloy (CRA), chrome alloy and coated casing may require specialized contact arrangements or further engineering review.
Standard inserts may not suit every damage-sensitive tubular.
Conductor Casing and Large-Diameter Well Construction
Selected well construction programs use large-diameter tubulars for conductor and surface casing installation.
SGPE offers CMS configurations up to 30 in and UC-3 configurations up to 42 in.
However, large-diameter work requires more than a matching nominal pipe size. Engineers must verify the casing body specifications, expected load, gripping arrangement, support equipment and available rig-floor space.
Offshore Drilling, Jack-Up Rigs and Drillships
Offshore casing-running projects require careful equipment matching and spare-parts planning.
Suitable casing slip configurations may support approved operations on fixed offshore platforms, jack-up rigs, semi-submersibles and drillships.
These applications can include surface casing installation, intermediate casing running, production casing handling and selected conductor casing programs.
Before ordering, offshore buyers should confirm the rig-floor equipment, mating dimensions, required inspection records and replacement-part quantities.
Deep-Well Drilling and Selected Oilfield Workover
Deep, directional and horizontal drilling projects require detailed casing-load planning. Properly selected slips provide stationary support during the relevant casing-running stages.
In addition, certain casing repair, recovery, replacement and well re-entry operations may require stationary casing suspension.
However, conventional casing slips do not replace tubing spiders, fishing tools or dedicated casing recovery equipment.
The project engineer must confirm that the selected model suits the intended operation.
How to Choose the Right Casing Slips
Selecting suitable casing slips requires a review of the casing string and its complete supporting arrangement.
Start with the actual casing OD. Identify the pipe diameter at the gripping location rather than selecting the tool by coupling size alone. Also provide the casing grade, wall thickness or unit weight.
Next, establish the maximum planned suspended load. The slip assembly and all supporting components must meet the applicable capacity requirements. UC-3 models have a published 250 US short ton rating, while CMS capacities require model-specific confirmation.
Then, identify the mating support equipment. CMS configurations require the correct insert bowl or casing bushing. UC-3 assemblies need matching chucks and linings with the designated taper.
For replacement projects, the original model, equipment nameplate, seating dimensions and technical drawings help establish the requirement.
Finally, review the gripping inserts and operating environment. Insert tooth geometry, retaining components and casing surface requirements can affect equipment selection. Offshore or project-specific applications may also require additional inspection documentation.
These checks help buyers prepare accurate specifications and avoid ordering equipment that matches the casing size but not the rig-floor support system.
Common Industry Casing Slip Models and Replacement Cross-Reference
Oilfield equipment buyers may encounter CMS-XL, CMSXL, CMS-3 and CPS Conductor Pipe Slips when identifying older casing-running equipment.
These established industry references describe different configurations and do not automatically correspond to SGPE’s CMS or UC-3 assemblies.
| Industry Model | Published Size Examples | Technical Reference | Replacement Consideration |
|---|---|---|---|
| CMS-XL / CMSXL | 6-5/8–30 in | Certain designs use a 4 in/ft diameter taper and circular button inserts | Confirm body, bowl and button specifications |
| CMS-3 | 9-5/8–30 in | Certain designs use a 3 in/ft diameter taper | Verify taper and supporting equipment |
| CPS Conductor Pipe Slips | 24, 26 and 30 in | Segmented conductor slips with hinge spacers | Confirm conductor OD, body geometry and support system |
The size ranges above describe published industry examples, not confirmed SGPE stock configurations.
Some CMS-XL-style assemblies use circular button inserts and hinged segment structures. Meanwhile, CMS-3 designs may use a different tapered support interface even when the nominal casing size matches.
Manufacturers may express taper as inches per foot on the diameter or through another ratio-based convention. Buyers should use the applicable drawing rather than assuming different taper notations are interchangeable.
For CMS-XL replacement slips, CMS-3 casing slip inserts or CPS conductor pipe slip enquiries, provide the original equipment model, part number, photographs and dimensions.
SGPE can review the information and confirm whether a suitable replacement option is available.
Casing Slip Inserts, Gripping Dies and Spare Parts
Casing slip inserts contact the pipe body directly and experience wear during repeated handling cycles.
Therefore, maintenance crews must inspect the gripping teeth, slip bodies and retaining components according to the manufacturer’s requirements.
SGPE supports enquiries for complete casing slip assemblies, replacement gripping inserts, casing slip dies, slip body segments and compatible spare parts.

For this reason, replacement parts should not be selected solely by casing OD.
For CMS-XL circular button enquiries, buyers should provide the original button type and complete set quantity. Published industry button counts do not automatically apply to SGPE equipment.
Inspection and Maintenance
Before operation, qualified personnel should examine the gripping bodies, inserts, retaining hardware and tapered seating surfaces.
They should check for cracks, deformation, excessive wear, missing components and abnormal damage.
The inspection should also cover the matching insert bowl, casing bushing, chuck or lining.
If personnel identify damaged or unserviceable equipment, they must remove it from operation and follow the manufacturer’s inspection and repair instructions.
After use, crews should clean the assemblies and protect them from impact, contamination and corrosion during storage and transportation.
API Spec 7K Manufacturing and Quality Requirements
SGPE manufactures its CMS Type and UC-3 Casing Slips according to API Spec 7K requirements for drilling and well-servicing equipment.
Material quality, dimensional accuracy and structural integrity matter because the gripping bodies and support interfaces must transfer substantial casing loads.
Depending on the selected configuration and agreed inspection scope, quality checks may include material identification, dimensional inspection and examination of gripping and load-bearing components.
Customers may also request relevant material records, dimensional reports, certificates of conformity or other project-specific documentation.
