Keystone is a leading provider of Oilfield Safety Clamps. We offer the Type C, T, & MP Safety Clamps. These are ideal to help safeguard against dropping strings of flush joint tubing, providing a shoulder to position strings of flush line pipe for welding, and many other applications.
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 takes 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.
We understand the critical requirements of the oil and gas industry and the need for high-quality tools and parts. Our equipment is manufactured from quality materials acquired from trusted vendors and are designed and precision-machined to meet and exceed API Standards (API 8C or API 7K Standards)).
With the API monogram stamped on our equipment, you can be sure you are getting high-grade equipment at a competitive price, made in the USA.
*Upon purchase, customers receive material and heat-treatment certifications included in their data packets.
Keystone offers the Type C, T, & MP Safety Clamps
The KET Type “MP” Safety Clamp is ideal to help safeguard against dropping strings of flush joint tubing while making up or breaking out the string. The multi-link design provides uniform pressure around the pipe reducing the risk of crushing or damaging the pipe. Each assembly is provided with its own aluminum box as a standard option.

The KET Type “C” Safety Clamp is one of the most valuable tools on the Rig Floor. It helps guard against dropping flush-joint pipe, streamlined drill collars, etc. into the hole while making-up or breaking-out the string. Literally, it has dozens of money and time-saving applications in oilfield work, in addition to giving increased protection against fishing jobs.
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 takes 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.
