Differences between ERW Steel Pipe and HFW Steel PipeHigh 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.

What is the difference between HFW and ERW?

High-frequency welding (HFW) is a solid resistance heat energy. The use of high-frequency current welding resistance heat generated in the workpiece so that the workpiece is heated to melt the welding area or near the surface of the plastic state, then applied (or not applied) forging force and achieve a combination of metals. Therefore, it is a solid phase resistance welding.What is the difference between HFW and ERW?High-frequency welding (HFW) is a solid resistance heat energy. The use of high-frequency current welding resistance heat generated in the workpiece so that the workpiece is heated to melt the welding area or near the surface of the plastic state, then applied (or not applied) forging force and achieve a combination of metals.What is a HFW steel pipe? - www.ugsteelmill erw hfi hfw welded carbon steel pipeDec 04, 2018 · 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.

What is a Welded Steel Pipe? About Welded or ERW Steel erw hfi hfw welded carbon steel pipe

Welded pipe (pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp that are formed, bent and prepared for welding. The most popular process for large diameter pipe uses a longitudinal seam weld. Spiral welded pipe is an alternative process, spiral weld construction allows large diameter pipe to be produced from narrower plates or skelp.What is HFW steel pipe? - Carbon Steel Pipe and FittingsIt should be noted that HFW pipe is a type of ERW pipe. High frequency welding (HFW) is a solid resistance heat energy. 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.Types of Oil & Gas Pipes: Seamless, ERW, LSAW erw hfi hfw welded carbon steel pipeDec 20, 2018 · The most common welding technique used for oil and gas pipes is the so-called high-frequency induction technology (ERW-HFI), consisting in the application of an induction current on the outer surface of the pipe able to generate a robust seam weld and join the two sides of the steel

Types of Oil & Gas Pipes: Seamless, ERW, LSAW erw hfi hfw welded carbon steel pipe

Dec 20, 2018 · The most common welding technique used for oil and gas pipes is the so-called high-frequency induction technology (ERW-HFI), consisting in the application of an induction current on the outer surface of the pipe able to generate a robust seam weld and join the two sides of the steel Pipe Manufacturing Process / Methods for Seamless & 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 welding; SAW- Submerged Arc Welding (Long seam & Manufacturing Process for Welded Pipes. How To Produce erw hfi hfw welded carbon steel pipeLess thickness pipe, mainly ERW / EFW or HFW welded pipe are formed by continues rolling method. In this method, a flat metal strip from the strip coil is feed into the series of roller assembled in line. These rollers gradually form the strip in the circular section. At the end of rolling assembly, this pipe is continuously welded by welding machine.

High Frequency Induction (HFI) Welded Pipe

The high-frequency induction (HFI) resistance pressure welding technique for longitudinal welding. The endless strip passes through rolling stands where it is shaped to an open pipe, which runs through a high-frequency inductor consisting of a metal coil with single or multiple windings.Electric Resistance/ Fusion Welded (ERW and EFW)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.Electric Resistance Welded Pipe, ERW Steel Pipes, Electric erw hfi hfw welded carbon steel pipeHigh-frequency electric resistance welding (ERW) steel pipe production, internal weld surface treatments are generally incomplete curettage (left weld reinforcement) and complete curettage (scraping will form the inner surface of the groove) in two ways, and the results were not ideal, will affect the overall performance of the steel pipe.

Differences between ERW and HFW Steel Pipe_news_Alloy erw hfi hfw welded carbon steel pipe

ERW pipe manufacturing process includes HFW. ERW have low, medium, high frequency welding processes, and HFW is specially for high-frequency electric resistance welding. The differences between ERW and HFW steel pipe, is EFW is a type of ERW process for ordinary and thin-wall thickness steel pipes.Differences Between SAW and ERW Pipe | Winsteel GroupERW 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.Differences Between ERW and HFW Steel PipeHFW is required in API 5L PSL2 ERW steel pipe According the API 5L and ISO 3183 specification, for PSL 2 pipes in welded process the HFW welding is a mandatory requirements for ERW steel pipes. As it is an improvement from the inherent problems of hardness, lack of fusion and susceptibility of stress corrosion cracking (SCC).
