What is the difference between British and American pipe tongs.
The chain type pipe at work, non articulated chain end is free, and the clamp handle is fixed or hinged, pipe clamping, rotating by friction between the pipe and winding its chain to achieve, and the torque by the meshing force of local cone and the front end of the clamp handle chain produced no, the clamp handle force on the pipe surface sites.
Chain type wrench. The utility model comprises a clamp handle and a chain hinged at one end with the clamp handle, and the front end of the pliers handle is provided with teeth which are meshed with the chain. Furthermore, the chain is hinged with the clamp handle through the connecting plate, namely one end of the chain is hinged with one end of the connecting plate, and the other end of the connecting plate is hinged with the clamp handle. The teeth at the front end of the clamp handle arc distributed in an arc.
Therefore, the chain type pipe provided by the utility model overcomes the defects of the existing chain tongs, not only can the metal pipe, and pipe fittings, pipe fittings, ceramic thin-wall plastic pipe fittings for clamping, rotating, does not have a bite, no damage to the surface of the pipe.
