API 7K Handling Tools Type WA-C Safety Clamps Oilfield Used for Oil rig Drilling Rig
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.
