The high frequency welding (HFW) is mainly used in ordinary or thin wall steel pipe. It includes contact welding and induction welding. Direct current welding is generally used for small caliber steel tubes. In general, HFW is one of ERW production methods, it adopts the high frequency welding process. So, ERW steel pipe includes HFW steel pipe. How are welded pipes made?How are welded pipes made?Welded Pipes are manufactured from Plate or continues Coil or strips. To manufacture welded pipe, first plate or coil is rolled in the circular section with the help of plate bending machine or by a roller in the case of continues process.Pipe Manufacturing Process / Methods for Seamless & Welded Pipe

Besides, owing to the almost clean and smooth surface, ERW pipes are easy to be applies with coating method. Welded steel pipe, such as water pipes, generally through the flat plate by welding after bending up, you can find a seam in the above; is generally thicker in diameter spiral weld.Difference between ERW, SSAW, LSAW - Alloy Pipe, Tubes ERW Pipes and Tubes steel bendsDifference between ERW, SSAW, LSAW. Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).Difference between Seamless & ERW Stainless Steel pipeNov 24, 2014ERW (Electric Resistance Welded) pipes are welded longitudinally, manufactured from Strip / Coil and can be manufactured upto 24 OD. ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through a electric charge.
ERW Welded Steel Pipe Manufacturing Method When the ERW steel pipe welding process, two electrodes, usually made from copper, are used to apply pressure and current. The electrodes are disc-shaped and rotate as the material passes between them. This allows the electrodes to stay in constant contact with the material to make long continuous welds.ERW Pipes and Tubes steel bendserw steel pipewhat is erw steel pipeerw pipewhat is erw pipeerw steel pipe spec sheetserw pipe weighterw pipe chinaerw pipe sizesERW Pipes and Tubes steel bendserw steel pipewhat is erw steel pipeerw pipewhat is erw pipeerw steel pipe spec sheetserw pipe weighterw pipe chinaerw pipe sizesERW Steel PipeBS1387 welded tubes, S235 S235JR welded pipes, S275 S275JR welded ERW pipe, S355JRH S355J2H welded tube ERW, St44 ST52 welding pipes ASTM A53 Gr.B HFI pipes EFW pipes API 5L Gr.B, X42, X46, X52, X56, X60, X65 X70

Rigid metal pipe and tubing tend to be made of copper, steel, stainless steel or aluminum, but are not the same thing. Generally, tube is measured by the outside diameter while pipe is measured by the inside diameter, so pipe may appear thicker than tubing of the same measurement. For example, piece of one-inch pipe will seem to have a greater diameter than a piece of one-itch tubing.Images of ERW Pipes and Tubes Steel bends imagesDifference Between Seamless And Erw PipeWelded steel pipe is supplying with steel strip or steel plate, through bending and different welding processes; Cost & Price difference between seamless and welded (ERW) Pipe Welded pipes are always cheaper comare to Seamless Pipes.

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.Differences between ERW Steel Pipe and HFW Steel Pipe
Welded pipe with filler material can be used in the manufacturing of long radius bends and elbow. Welded pipes are cheaper with compared to the seamless pipe and also Weak due to the weld. There are different welding methods used to weld the pipe. ERW- Electric Resistance Welding; EFW- Electric Fusion Welding; HFW- High-frequency weldingProducts - Stainless Steel Pipes and Tubes - Welded or ERWElectric Resistance Welding (ERW) pipe is manufactured by rolling metal and then welding it longitudinally across its length. Seamless pipe is manufactured by extruding the metal to the desired length; therefore, ERW pipe have a welded joint in its cross-section, while seamless pipe does not have any joint in its cross-section through-out its ERW Pipes and Tubes steel bendsProject Report on ERW STEEL PIPE AND TUBE - ERW steel pipes & tubes find widespread usage across industries and fields.
