Overview Of Safety Clamp Type Mp And Drill Pipe Elevators

1. Overview Of Safety Clamp Type Mp And Drill Pipe Elevators The safety clamps basically come in three different types, and are manufactured by various companies around the globe. The most common name on the drill floor is “Dog Collar”. Again, as I have highlighted in the blog on slips, avoid mixing parts from one manufacturer with the other, even though they might seem compatible. Warranty on the tool is gone, and as tolerances on the parts might slightly differ, you could end up in a world of hurt. When we speak about safety clamps, we can divide them in three categories. The smallest size being a “T” Type, the intermediate & larger sized clamp is type “C” and there is the “MP” type which stands for Multi-Purpose is safety clamp type MP. The “C” & “MP” type overlap each other in sizes, however the “MP” is generally heavier and harder to handle. To open the T and C type clamp, pull the end link pin. On the safety clamp type MP, loosen the nut, releasing tension so it can swing open. Holding the handles, wrap the clamp around the pipe like a belt. Insert pin or on MP, push the screw back into the screw latch link segment, turning the nut to tighten. Use wrench to torque nut. The end user determines the clamping torque necessary to prevent marking/damaging tubular. With the clamp installed, the spring loaded tapered inserts are designed to firmly grip and wedge against

Warning: •Safety Clamps are not designed to hold or hoist the string weight – use in conjunction with slips. •Safety Clamps are made from cast alloy steel and should not be welded in the field. Improper welding can cause cracks and brittleness in repaired area and can result in drastic weakening of the Safety Clamp and Parts and possible Failure. •Repairs which involve welding and or machining by others that is not authorized by BVM will void the warranty. •Using Safety Clamp which has been improperly welded can result in serious bodily harm and property damage. •Use the handles for lifting the Safety Clamp. •Only use the Safety Clamp within the specified temperature rating, which is -4°F to 150°F unless otherwise specified.

3. Slips are wedge-shaped gripping devices which are used to suspend the drill string in the hole. They fit around the body of drill pipe elevatorsand wedge in the taper of the rotary table’s opening. Slips have serrated inserts or dies that will grip the outside diameter of the tubular when it is set on the rotary table. To set the slips, rig crews place them around the pipe and the driller then slowly lowers the pipe until the slips can take up the load. The dies in the slips will firmly hold the pipe. In order to remove the slips, rig crew grasp the slip handles and as the driller picks up the pipe, they lift them out of the rotary table opening and set them aside.
