You can also request OEM and ODM orders along with the option of going for customized packaging and ERW Carbon Steel Tube Making Machinery - HNGK ERWStraight seam welded pipe mill also is called ERW mill. The plate in certain width after slitting line and stripping is unfolded and leveled. Then, they are sent into forming machine. Used the roller, the plate is bent into pipe state. The edge of the steel plate is melted by making use of the proximity effect and skin effect of high frequency

ERW Steel Pipe, China Electrical Resistance Welded Pipe

ERW steel pipe is a straight seam electric resistance welded pipe, a steel pipe whose weld is parallel to the longitudinal direction of the steel pipe. It has sturdy frame which is strong enough to make sure the stable operation. And it is resistant to water, oxygen and corrosion, which is endurable with long life span. Production Process of Straight Seam Welded PipeApr 30, 2021 · Straight seam steel pipe is a steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. Straight seam steel pipes can be divided into high-frequency straight seam steel pipes ( ERW tube ) and submerged arc welded straight seam steel pipes ( LSAW tube ) according to the production process.

Production Standard of High Frequency Straight Seam

Apr 28, 2020 · The high-frequency straight seam welded pipe is generally produced with a small diameter, and the outer diameter is generally less than 660mm or 26 inches. Its characteristics are:fast welding speed, for example, for steel pipes with an outer diameter of less than 1 inch, the maximum welding speed can reach 200 meters / minute. Straight seam high frequency ERW pipe tube mill Zhongtuo Straight seam high frequency ERW pipe mill/tube mill. Straight seam high frequency ERW pipe mill/tube mill is specially used for producing 10-200mm, 0.4-6.0 mm high-frequency straight seam welded pipe and corresponding square pipe (17*17-62*62mm,1.2-3.0mm). The composition of equipment is from uncoiler to fixed length cutting saw.

Welded Steel Pipes Supplier Philippines Welded Pipe

Electric Fusion Welded (EFW) Pipe is a welded pipe formed by rolling plate and welding the seam. The EFW pipe is the most popular process for large diameter pipe uses a longitudinal seam weld. The welds are made by heating with an electric arc between the bare metal electrodes. Applicable only to Carbon Steel Pipes. LSAW PIPES (Straight Welded What are the uses of straight seam welded steel pipe?(it is named because the welded joint of steel pipe is in a straight line). LSAW steel pipe and ERW steel pipe are two kinds of Longitudinal welded pipe. LSAW can be divided into UOE, RBE and JCOE steel pipes according to their different forming methods There are two kinds of straight seam welded steel pipe according to the specified wall thickness:ordinary steel pipe and thickened steel pipe.
