seam welded erw round steel tube and pipe Description

Are welded steel pipes better than seamless?Are welded steel pipes better than seamless?Generally the welding seam of the welded steel pipe is the weak point, the quality affect overall performance. In general, welded steel pipes can withhold 20% less working pressure than seamless ones. This reliability is the prime factor why people go for seamless steel pipe.What is the Difference Between Seamless Pipes & Welded / ERW Pipes ERW steel pipe/tube making machine for round, square and seam welded erw round steel tube and pipe

ERW steel pipe/tube making machine, the process is unwinding the steel coil and make the head and tail of the coil butt-welded in the strips preparation section. Then the strips fed into accumulator and pulled out of the accumulator at a constant speed passed through the unit. Next, the strip is formed into an open tube in the forming unit.

How does welding seam work?How does welding seam work?Welding seam is in longitudinal. During the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond.Petrosadid Electric Resistance/ Fusion Welded (ERW and EFW) What is an electric steel pipe?What is an electric steel pipe?ERW steel pipe is formed by rolling plate and welding the seam.

Cut about 100mm welded pipe, place it under the hydraulic press, the position of the weld is perpendicular to the direction of the hydraulic press, start the oil pressure, slowly press the welded pipe, press it to 3/4 of the diameter, and check whether the weld is cracked. If there is no crack, weld the seam; if there is crack, adjust the welding process parameters in time.
