Audited Supplier Safety Clamps are necessary tools for handling drill collars, flush joint pipes and small shoulder pipes. They could adjust pipes of different sizes by changing the quantity of chain links. They are designed and manufactured according to API Spec 7K.
The Safety Clamp consists of individual links, flexibly hinged together. Each link has a separate tapered slip which acts as a gripping member, much like a tapered rotary slip, and each slip is held in a retracted position on the taper by spring tension. When the clamp is tightened, each small slip take a firm initial grip on the surface of the pipe. Should the pipe start to fall, or should load increase occur against the slips, the taper mounting causes each slip to wedge tighter against the surface of the pipe to increase the grip or lock the pipe against further movement.
Gripping pressure is always uniform around the pipe so there is little danger of crushing thin-walled pipe or damaging the pipe surface. And, since each link, complete with tapered slip, is interchangeable as a unit, the Safety Clamp is readily adaptable to virtually any diameter. Each link changes the effective gripping diameter of the clamp one inch. All parts are made of alloy steel, heat-treated for strength and gripping ability.

3.Type MPPI 7K SDS SDML SDXL Rotary Drill Pipe Slips
Drill pipe slips have a taper of 4"/foot on diameter and other suitable dimensions to permit operation in standard master bushings. The right size drill pipe slips must always be used for the size drill pipe being handled. Slips that are smaller than the drill pipe will damage the pipe and the corners of slips as well as risk dropping a string of drill pipe entirely. It is paramount that the right size is chosen and used to avoid catastrophic damage to the drill string. Slips that are too large will not contact the pipe all the way around. This risks dropping the pipe and destroys the center part of the gripping surface.
Drill pipe slips Type SD can accommodate drill pipes from 2-3/8 to 7 inch. They are classified as type Short(SDS), Medium(SDML), Extra Long(SDML).SDS slips are designed for shallow hole drilling, SDML slips are the perfect choice for all medium depth drilling and SDXL slips are designed for deep drilling. The slips are designed and manufactured in API Spec 7K and SY/T 5049 Slips for well drilling. It is suitable to handle the drill rods during the oil well drilling operations for the exploration of petroleum and natural gases ,It is an essential tool for coupling and uncoupling.
