ERW electric resistance welded pipe
ERW is the abbreviation of electric resistance welded pipe, the welding seam is merged by melting the base material of the steel body, there is no other intermediate welding medium, therefore the mechanical strength is better than that of general welding pipes. This pipe type has the features of high production efficiency and relatively lower cost. It is one of the main pipe types for the construction of oil and gas pipelines, it is also commonly used for the structural pipes. 

The electric-resistance welding has the features of high production efficiency, low cost, material saving and easy automation etc., therefore it is widely used in the respective industrial sectors such as aviation, aerospace, energy, electronics, automobile, light industry etc. it is one of the important welding process.
