ERW have low, medium, high-frequency welding processes, and HFW are especially for high-frequency electric resistance welding. The difference between ERW and HFW steel pipe is EFW is a type of ERW process for ordinary and thin-wall thickness steel pipes.

Differences Between ERW and HFW Steel Pipe

ERW steel pipe includes HFW steel pipe ERW is the general term for electric resistance welded steel pipe. It can be divided into two types alternating current welding (AC) and direct current welding (DC). According to the different frequency, AC welding can be divided into low frequency welding, intermediate frequency welding, ultra high Electric Resistance High Frequency Zhangzhou Steel PipesDifferences Between Electric Resistance Electric Resistance High Frequency Zhangzhou Steel Pipes - Permanent SteelHigh-quality steel pipes require heat treatment on the weld line or off-line to refine the microstructure of the weld zone. The weld of the high-quality ERW welded pipe can reach the same level of toughness as the base metal, which cannot be achieved by the submerged arc welding process. EFW is the abbreviation of electric fusion welding.Differences Between Electric Resistance Electric Resistance High Frequency Zhangzhou Steel Pipes - Permanent SteelHigh-quality steel pipes require heat treatment on the weld line or off-line to refine the microstructure of the weld zone.

Differences between ERW Steel Pipe and HFW Steel Pipe

High frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHZ. Through high-frequency current welding resistance, the heat generated in the contact objects, so the objected surface are heated to the plastic state, then with or without forging to achieve a combination of steels.Differenciating between straight seam and electric Electric Resistance High Frequency Zhangzhou Steel PipesJan 28, 2019The high-frequency straight-slit electric resistance welded steel pipe is formed by the skin effect and the proximity effect of the high-frequency current after the hot-rolled coil plate is formed by the molding machine, and the edge of the tube blank is heated and melted, and pressure welding is performed under the action of the pressing Electric Resistance High Frequency Zhangzhou Steel PipesELECTRIC RESISTANCE WELDED PIPES - Meever KonnectionELECTRIC RESISTANCE WELDED PIPES ELECTRIC RESISTANCE WELDED PIPES The High-Frequency Longitudinal Seam Welded Steel pipe is also called ERW steel pipe.

Electric Resistance Welded - an overview ScienceDirect Electric Resistance High Frequency Zhangzhou Steel Pipes

Apr 03, 1993Electric (resistance) welding is done by passing electric current (by induction or direct contact) across the edges which are joined under pressure, without filler metal. Heat treatment at least of the weld zone is usual in sizes larger than DN 200.
