Pneumatic pipne line-up clamp with copper liner is a special tool to ensure the quality of welded surface of pipe mouth in pipeline welding.In previous pipeline welding, because the back of weld pool is suspended, there are some problems, such as threading, undissolved, poor weld back forming and so on.Need to fill and repair welding, cover welding and so on, increase the workload.The use of a copper liner can solve this difficulty and make the back of the nozzle smooth.
In addition, our copper liner has high thermal conductivity, fast heat loss and extremely fast cooling rate
The thermal conductivity is more than 11 times larger than that of the pipeline, so that a lot of heat is lost from the substrate during welding.
It is difficult for the copper liner surface to reach the melting temperature, and the copper water will not penetrate into the pipeline.The copper liner was developed in 2012 and has been used in the construction of China's west to east gas pipeline to Zhongwei pipeline with good effect and won the national patent.
