Differences Between ERW and LSAW Steel PipeSep 24, 2020 · The raw material of ERW steel pipe is hot rolled steel coil, and the raw material of LSAW steel pipe is hot rolled steel plate. Therefore, ERW steel pipe can realize continuous assembly line operation with high production efficiency and low production cost; while SAW steel pipe is processed by steel plate, continuous assembly line operation cannot be realized, and the production efficiency is
Electric Resistance Welded - an overview ScienceDirect When electric resistance-welded carbon steel pipe was exposed to aggressive waters, grooves caused by the redistribution of sulfide inclusions along the weld line were formed in the weld. The material at the bond line is anodic to the surrounding material and the result is a V-shaped groove with the apex of the V centered on the bond line.
Hot-dip galvanizing (HDG), as referenced is the process of dipping fabricated steel into a kettle or vat of molten zinc. While the steel is in the kettle, the iron metallurgically reacts with the molten zinc to form a tightly-bonded alloy coating that provides superior corrosion protection to the steel.

The hot expand seamless steel pipe you can find on the site are generally built using hot-dipped technology to prevent rusting and weakening of the structural elements. With seamless welding quality, these hot expand seamless steel pipe are annealed with nitrogen protection and are polished with utter professionalism.
What is EFW steel pipe - pipelinedubaiEFW steel pipe (Electric Fusion Welding steel pipe) refers to an electron beam welding, the use of high-speed movement of the electron beam directed impact kinetic energy is converted to heat the workpiece so that the workpiece leaving the melt, the formation of the weld. EFW steel pipe is formed by rolling plate and welding the seam.
What is ERW steel pipe - pipelinedubaiAll help to improve the welding quality, and expand its application areas. ERW Pipe Manufacturing Process (ERW) Electric resistance welded pipe is manufactured by cold-forming a sheet of steel into a cylindrical shape. Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.
