What is an EFW pipeline?
Electrofusion welding (EFW) steel pipe refers to electron beam welding, which uses the high-speed movement of the electron beam to convert the directional impact kinetic energy into heating the workpiece, causing the workpiece to leave the melt and form a weld.
A672 CC70 straight seam steel pipe is a steel pipe material for high temperature and high pressure vessels. A672 CC70 carbon welded steel pipe has a higher carbon content, so it has higher yield strength, tensile strength and wear resistance. A672 CC70 alloy welded pipe is suitable for more Industrial equipment with high temperature and higher pressure has stable performance and long service life.
