The first use of forceps, often can not move the pipe clamp, ask how to correctly use the wrench?
The utility is generally used for clamping and rotating steel tools, pipe tools manufacturing Emerson pipes are widely used in oil pipelines and piping installation. You can make it through the pipe clamp clamp rotation to complete the connection, the working principle is to clamp force into the torque in the twisting direction more force also can be more tightly pipe clamp.
Methods of use and precautions:1, to choose the right specifications2. The opening of the tong head is equal to the diameter of the workpiece;3, clamping head to tighten the workpiece, then pull hard to prevent slipping;4, with the boosting rod length should be appropriate, not too hard or exceed the allowable strength pipe;5, the clamp teeth and adjusting ring to keep clean.
In general, the torque is increased by the taper of the jaw, usually at 3-8 degrees, and the tube is tightened and automatically adapted to different diameters. It automatically adapts to the plastic deformation caused by the stress exerted on the tube by the jaw. Emerson pipe tools said that in the presence of this effect of reducing the pipe diameter, to ensure torque, without slipping.
Use a pipe wrench, should first check whether the firm fixation pins, pliers, pliers handle has no cracks, cracks can not be used; the smaller pipe, not too much force, not with a boosting rod, can not use a pipe wrench as a hammer or crowbar. In addition, wash the grease immediately after use and apply the butter to prevent the rotating nut from rusting and return to the tool carrier or inside the tool room.
