Description
DU Type Rotary Drill Pipe Slip API 7K for Petroleum Drilling
SGPE DU Type Rotary Drill Pipe Slip is an API Spec 7K oilfield rotary slip used for drill pipe gripping, holding and suspension on drilling rig floors. The DU series includes DU, DUL and SDU models for different drill pipe sizes, rotary table systems, insert bowl configurations and rig floor handling conditions.
These rotary drill pipe slips work with rotary tables and insert bowls during tripping, pipe connection, pipe disconnection, workover and well servicing operations. They keep the drill pipe stable when the drill string moves through the rotary table or needs temporary suspension on the rig floor.
The DU series covers drill pipe outside diameters from 2 3/8 in to 7 in, equal to 60.3 mm to 177.8 mm. Drilling contractors can select the proper DU, DUL or SDU model according to drill pipe OD, rotary table size, insert bowl type, well depth and expected handling load.
SGPE manufactures DU Type Rotary Drill Pipe Slips from high-strength alloy steel. Precision-machined slip bodies, replaceable inserts and a stable taper structure give the slips firm gripping performance, accurate equipment fit and long service life in oilfield drilling environments.
For heavier drilling work, the SDU type offers a larger taper contact area. This design distributes load more evenly and improves pipe holding stability during deep well drilling, heavy-duty drill pipe suspension and high-load rig floor operation.
Rotary slips play an important role in pipe handling safety and rig efficiency. During tripping, connection or temporary suspension, the crew needs a slip that matches the drill pipe OD, fits the rotary table equipment and grips the pipe with consistent force. SGPE DU Type Rotary Drill Pipe Slip meets these needs for petroleum drilling, oilfield workover and well servicing applications.
Key Features of DU Type Rotary Drill Pipe Slip
API Spec 7K Oilfield Rotary Slip
SGPE manufactures DU Type Rotary Drill Pipe Slips according to API Spec 7K requirements for drilling and well servicing equipment. Oilfield rotary slips often work under heavy loads, repeated rig floor use and harsh wellsite conditions, so material strength, dimensional accuracy and equipment fit all matter.
The API 7K design gives drilling contractors, rig operators and procurement teams a clear reference when selecting rotary drill pipe slips for oilfield projects. It also supports compatibility with common rotary table systems and insert bowls.
Wide Drill Pipe OD Range
The DU series handles drill pipe OD from 2 3/8 in to 7 in. This range covers common drill pipe sizes used on petroleum drilling rigs, workover rigs and well servicing units.
A correct OD match allows the slip inserts to grip the pipe body securely. It also lowers handling risk during lifting, lowering, tripping and rotary table suspension. For buyers who need one slip series for several field conditions, DU Type Rotary Drill Pipe Slips offer a practical and flexible choice.
DU, DUL and SDU Models Available
SGPE supplies DU, DUL and SDU drill pipe slips for different rig floor handling requirements. Customers can choose the proper model according to drill pipe OD, slip body size, rotary table size, insert bowl configuration and expected operating load.
DU slips suit standard rotary table pipe handling.
DUL slips fit heavier drilling and workover conditions.
SDU slips provide a larger taper contact area for better load distribution during deep well drilling and heavy-duty drill pipe suspension.
Strong Grip for Rotary Table Pipe Handling
The replaceable slip inserts grip the drill pipe body firmly and reduce the risk of pipe slippage during tripping, pipe connection and rotary table suspension. This grip keeps the drill string under control and makes rig floor operation smoother.
During daily drilling work, the crew must control the pipe as it moves through the rotary table. A well-matched rotary slip keeps the pipe stable, reduces handling delays and allows drilling or workover work to continue more efficiently.
Larger Taper Contact Area for SDU Type
The SDU type uses a larger taper contact area than standard slip designs. This structure spreads the load more evenly and gives the slip stronger holding stability under heavy-duty drilling conditions.
Operators often choose SDU rotary drill pipe slips for deep wells, high-load drill string suspension and demanding rig floor operations. When drilling depth increases or pipe handling load becomes heavier, the SDU model gives the crew a stronger and more suitable option.
Forged Alloy Steel Slip Bodies

Precision machining improves the fit between the slip body, rotary table and insert bowl. A proper fit improves load transfer, pipe gripping and daily rig floor handling performance.
Replaceable Slip Inserts
The insert design allows quick replacement and convenient maintenance. Operators can replace worn inserts without changing the complete slip body, which reduces maintenance cost and keeps the equipment ready for the next job.
Replacement inserts also maintain consistent gripping performance during drilling, workover and well servicing. When customers request inserts, they should provide the slip model, drill pipe OD and current insert specification.
Practical Rig Floor Use
SGPE DU Type Rotary Drill Pipe Slips support common rig floor tasks such as tripping, pipe connection, pipe disconnection, drill string suspension and well servicing.
The slips match standard rotary table equipment and insert bowls, so drilling contractors can use them for new rig packages, spare part replacement and field maintenance projects.
Applications in Petroleum Industry
Petroleum Drilling Rig Operations
Operators use DU Type Rotary Drill Pipe Slips on petroleum drilling rigs to grip and suspend drill pipes during rotary drilling, tripping, pipe connection and pipe disconnection. The slips hold the drill string in the rotary table while the crew makes or breaks connections.
Drill pipe handling requires strength, accuracy and stable equipment fit. A suitable API 7K rotary slip keeps the pipe under control, supports safe suspension and improves rig floor efficiency.
Oilfield Rotary Table Pipe Handling
DU Type Rotary Drill Pipe Slips work with rotary tables and insert bowls to hold drill pipes while the drill string moves up or down. They also support temporary suspension when the crew stops the pipe string for connection, inspection or operating adjustment.
This application makes the DU series an important part of oilfield rotary table pipe handling. Buyers often search for related terms such as rotary table slips, drill pipe slips, oilfield rotary slips, API 7K drill pipe handling tools and rotary slip for drill pipe when they need this type of equipment.
Workover Rig Operations
Workover crews can use DU rotary drill pipe slips during well maintenance, well repair, re-entry operations and oilfield intervention tasks. These jobs involve frequent pipe movement, so the slips must grip the drill pipe securely and release it smoothly when required.
For workover rigs, the right rotary slip reduces handling delays and supports safer operation around the rig floor. SGPE can recommend suitable DU, DUL or SDU models according to drill pipe size, rotary table configuration and field operating condition.
Well Servicing Operations
In petroleum well servicing, DU Type Rotary Drill Pipe Slips support drill pipe handling when crews service oil wells, maintain production wells or perform downhole service operations. These applications often involve repeated lifting, lowering and suspension of tubular goods.
A durable rotary drill pipe slip keeps the pipe under control during service work. It also improves equipment compatibility when the well servicing unit uses rotary table systems and insert bowls.
