The manufacturing process consists of roll-forming a strip of steel into a tubular section and then subsequently welding the edges together using electric resistance to first heat up the edges and then subsequently forging them together. Electric Resistance Welded Tubing Industrial Tube and Cold rolled electric welded (CREW) tube is produced per ASTM A513 Type 2. CREW is produced from hot rolled strip steel that has been cold reduced. Due to the extra cold working at the steel mills, A513 Type 2 tubing will have tighter wall thickness tolerances, improved surface condition and a narrower range of mechanical properties than A513 Type 1.
