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).
If compare ERW pipes with SAW pipes, ERW pipes surface quality is better. ERW pipes are smooth and have a better finish. In most of the SAW pipes, it is mainly about the weld reinforcement internally and externally. Third, the Defects Found in ERW Pipes Are Lesser Than SAW Pipes. We will see it from the defects. As there is a solvent deposit in
EFW pipe vs ERW pipe - Sunny SteelEFW pipe vs ERW pipe. Electric Fusion Welding (EFW 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.. It is mainly used for welding dissimilar steel welding sheet or which high power density, metal weldment can
ERW Pipes, HFW Pipe Manufacturer & SupplierThe High-Frequency Longitudinal Seam Welded Steel pipe is also called ERW steel pipe, it's 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.
ERW Tube means Electric Resistance Welded tube. ERW steel tube is used for various engineering purposes, fencing, scaffolding, etc. ERW steel tube is available in various shapes; square, rectangular, round and oval and various finishes, wall thicknesses and diameters and has a
ERW/HFW Steel Pipe Galvanized ERW Steel PipeERW/HFW Steel Pipe Galvanized ERW Steel Pipe. Hot-dip Galvanized Coated ERW Steel Pipe. One of the most widely used materials on Earth, steel provides outstanding strength, toughness, and durability. Steel pipe is a versatile, cost effective solution for a broad range of applications, including:

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).
HFW Pipe API 5L - HYSP Steel Pipe SupplierHFW Pipe API 5L. HFW pipe refers to EW pipe produced with a welding current frequency equal to or greater than 70 kHz. ERW Pipe VS HFW pipe. ERW pipe refers to electric resistance welding pipe. Its one kind of welded pipe without flux.ERW pipe is manufactured from the longitudinal welding of steel.
Steel Pipe, OCTG, Casing and Tubing Supplier - OctalERW 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.
The weld seam of HFW pipe is heat treated after welding that no untempered martensite remains. And the weld flash can be removed from both inner and outer surfaces. We provide welded steel pipe as standard:ASTM A53 Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded ASTM A135 Electric-Resistance-Welded Steel Pipe
Welded Standard & Line Pipe US Steel Tubular Products*U. S. Steel Tubular Products ERW pipe is HFW as defined by API 5L. ERW standard pipe and high frequency electric-welded line pipe are widely used throughout the oil and gas industry, as well as for pipe piling and cable pipe systems. With over a century of producing steel products for the energy business, U. S. Steel Tubular Products offers a
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.
