API 7K Type MP Drill Collar Safety Clamps for 1-1/8" to 36 1/8" Pipe Diameters - Oilfield Drilling Equipment
API 7K Type MP Drill Collar Safety Clamps are essential safety tools for oilfield drilling operations, designed to securely grip and hold drill collars, flush joint pipes, and small shoulder pipes during handling procedures.
The safety clamp features individual links flexibly hinged together, with each link containing a separate tapered slip that functions as a gripping mechanism. Spring tension maintains slips in retracted positions until the clamp is tightened, when each slip takes firm initial grip on the pipe surface. If pipe movement occurs or load increases, the tapered mounting causes slips to wedge tighter against the pipe, increasing grip strength and preventing further movement.
- Uniform gripping pressure distribution prevents crushing of thin-walled pipes
- Minimizes surface damage to pipe materials
- Interchangeable link units for diameter adaptability
- Each link adjusts effective gripping diameter by one inch
- Constructed from heat-treated alloy steel for superior strength
- Compliant with API Spec 7K for drilling and well servicing equipment

- Type MP - For drill collars, flush joint pipes, and small shoulder pipes
- Type C - Accommodates pipes from 1-1/8" to 15-5/8"
- Type T - Handles flush joint pipes and drill collars
