316 tube Factory – erw welded steel seam pipe efw pipe for gas – Future Metal
316 tube Factory – erw welded steel seam pipe efw pipe for gas – Future Metal Detail:
During ERW pipe welding, heat is generated when current flows through the contact surface of the welding area. It heats the two edges of the steel to the point where one edge can form a bond. At the same time, under the action of the combined pressure, the edges of the tube blank melt and squeeze together.
Usually ERW pipe maximum OD is 24” (609mm), for larger dimensions pipe will be manufactured in SAW.
What kind of pipes (standards) could be made in ERW processes?
There are a lot of pipes could be manufactured by ERW process:
Carbon steel pipe in ERW
ASTM A53 Grade A and B (and Galvanized)
ASTM A252 pile pipe
ASTM A500 structural tubing
ASTM A134 and ASTM A135 pipe

High-frequency straight seam electric-resistance welded steel pipe(erw steel pipe) is hot-rolled coil after forming machine, the use of high-frequency current skin effect and proximity effects, the tube edge heating and melting, squeeze roller under pressure welding to achieve production.
High-frequency resistance welding steel pipe, welding pipe and ordinary welding process is not the same, the weld is made of the base metal melt from the body, the mechanical strength is better than the general pipe. Smooth appearance, high precision, low cost weld high and small, favorable 3PE anti-corrosion coating. There are significant differences in the welding methods between high frequency welded pipe and submerged arc welded pipe. As the welding is done instantly at high speed, the difficulty of ensuring the quality of welding is much higher than that of submerged arc welding.
