Long-distance Oil/Gas Pipeline Aligning Device for On-site Welding
Pipeline aligning device is a special machine used to implement pipe connection in welding construction of pipe-pipe circular weld.At the on-site welding of long-distance oil and gas pipeline,clamps' fuction and using effect is one of the important influencing factors which can affect the welding quality and construction progress of the pipeline project.Going along with aligning device and the way of pipe connection in on-site construction of domestic pipeline,the mechanical structure,working principle,advantages and disadvantages of some typical external and internal clamps were introduced,and the guidance suggestion for chosing aligning devices in pipeline construction were put forward.
