The didderence of ERW, HFW welding processes. ERW welding process refers the heat generated by the resistance to current flowthat pass through the jointed metals. So a large current is. needed to electrify the whole surface of the steel plate or coil to the length of welding. In the ERW welding process, the electric current that 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 - ZAFFERTECERW cold pipes are formed by drawing a ribbon of steel through a series of rollers and mechanically forming it into a tube. This is welded by means of an electric charge. The weld joint is achieved without the addition of any filler metal. The use of superior grade steel results in a product with high strength, corrosion resistance, high
ERW/HFW Transmission Pipe:standard:API 5CT,API 5L, ISO 3183, EN 10217-1, Transmission Pipe:Use For conveying gas, water and oil either in the oil or natural gas industries ERW Structural Pipe Standard:ASTM A53/A53M, ASTM A252, EN10219-1, AS/NZS 1163, AS/NZS 1074, ASTM A500, Structural Pipe:Uses:for kinds of structural component,parts Electric Resistance Welded Pipe, ERW Steel Pipes, Electric ASTM A178 standard referes to electric-resistance-welded tubes with minimum-wall-thickness. Materials are carbon steel and carbon-manganese steel, ASTM A178 pipe and tube is to be used in boiler tubes, boiler flues, superheater flues and safe ends. HFW Carbon Steel Pipe ERW - Touch of SilverERW Steel Pipe, Welded Steel Pipe, Carbon Steei Pipe manufacturer / supplier in China, offering API 5L/ASTM A53/JIS G3454 STPG370 ERW/HFW Carbon Steel Pipes, Steel Pipe with API5l Certification Under X42-X60 Psl-2 Material, Jisg3444 Stk400 ERW Steel Pipe and so on.
JK Materials International - Korea supplier of Carbon Steel pipe, ERW/HFW Pipe, Stainless Steel Welded Pipe, Stainless Steel Pipe Petrosadid: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. Pipes - ZAFFERTECSeamless Carbon Steel and Stainless Steel Pipes. HFW pipes are made from hot rolled flat steel strip, formed into a tubular shape. Electric Resistance Welded Pipes (ERW) ERW cold pipes are formed by drawing a ribbon of steel through a series of rollers and mechanically forming it into a tube. This is welded by means of an electric charge.
NIPPON STEELs ERW pipe mills produce pipe with outside diameters from 4-1/2 inches (114.3 mm) to 24 . inches (609.6 mm). The equipment to produce such pipes reflects NIPPON STEELs intent to meet the great demand for larger and heavier steel pipe. Wall Thickness. To produce pipe with wall thickness up to 0.866 inches Ratnamani Metals & Tubes Ltd.Carbon Steel Electric Resistance Welded/ High Frequency welded pipes (ERW/HFW) 6NPS [168.5 MM] to 18NPS [457.2 MM] 0.125[3.2 MM] to 0.5 [12.7MM] As per ASTM As per API 5L, API5CT As per EN / BS As per IS As per Customers specification Types of Oil & Gas Pipes:Seamless, ERW, LSAW ERW pipes are available in sizes between 1/2 and 20 inches, in carbon steel (ASTM A53 is the most common specification) and stainless steel (ASTM A312). In terms of dimensions, the ASME B36.10 and ASME B36.19 are the key reference specifications (API 5L for welded ERW line pipes).
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). 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.
