Difference Between Seamless And Erw Pipe

All Carbon steel pipe such as Casing pipe and Tubing pipe made to API specifications uses seamless or electric-weld supplying processes. There are many Differences between Seamless ERW HFW steel pipeamp; ERW Pipe. The main Difference is that the Seamless Piping is suppliers by hot-working steel or, if necessary, by subsequently cold-finishing the hot-worked product

Difference between Seamless ERW HFW steel pipeamp; ERW Stainless Steel pipe

ERW (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. Differences Between ERW and HFW Steel PipeERW 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

Differences Between ERW and HFW Steel Pipe

HFW 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). ERW Steel Pipe HFW Steel Pipe HunapipeHFW welded steel pipes are widely preferred in Oil, Natural Gas, Water and other liquids transportation and distribution lines, heating, cooling, ventilation piping and steel structures for construction and other general purposes by means of precise production tolerances and high capacity manufacturing method.

What is HFW steel pipe?

It 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. What is a HFW steel pipe? - ugsteelmillThe 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 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. Differences Between ERW Steel Pipe and HFW Steel Pipe ERW steel 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.
