Clamp coupling is a clip used to fix a pipe. In order to meet the construction of modern high-rise buildings, there are high requirements for the fixed installation of concrete clamp. The clamp should be easy to assemble and disassemble, also the clamp is better fixed in order to prevent twisting caused by vibration at the concrete output.
Therefore, it is necessary to provide a base-type clamp for concrete pump, which can protect the connected concrete pump pipes while protecting the clamp coupler.
The bolt clamp is made of 40Cr, and it have good comprehensive mechanical properties, good hardenability of steel, high surface hardness and wear resistance.

The bolt clamp is used for fixing concrete pumping pipe, concrete pumping rubber hoses.
