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.
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.

EFW (Electric Fusion Welding) Steel PipeEFW (Electrofusion welding) steel pipe is electron beam welding, directed impact kinetic energy electron beam, the use of high-speed movement into a hot workpiece to leave the workpiece melting, the formation of the weld. EFW pipes are formed from hot-rolled plates and welded welds. Welding flashes can be removed from the outside or inside

The seam of the can is welded and then individual cans are welded together to make the finished pipe. Rolled and welded pipe can be made in diameters of up to 16 feet and over 2.0 inches in thickness. Spiralweld pipe, like ERW pipe, is also manufactured from steel coil.

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.
ERW pipe manufacturing process includes HFW. ERW have low, medium, high frequency welding processes, and HFW is especially 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. Seamless steel pipe|carbon steel pipe|Stainless steel pipe As a professional manufacturerDMH United Steel Industry offer you the best steel pipes,such as Carbon pipes,seamless steel pipe,stainless steel pipe,welded pipe,ERW,SSAW,LSAW and pipe Stainless Steel EFW Pipe SS 304/316 EFW PipeStainless Steel 316 EFW Pipe manufacturer in India. Stainless Steel Efw Welded Pipe is a type of stainless steel pipes that is produced through electric fusion welding. The electric fusion welding is a process in which high voltage electricity is passed onto the material to heat and melt it.
Stainless Steel Pipe are utilized in ventures that are requesting in light of the fact that they offer amazing impervious to erosion. These SS Pipe are accessible in various classes, evaluations and types and they are utilized in a wide number of uses, for example, dairy and sustenance preparing, engineered strands, oil and gas handling, refinery and petrochemicals, water treatment offices Welded Standard & Line Pipe US Steel Tubular ProductsERW 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 variety of manufacturing methods to produce steel pipe that can meet Welded vs. seamless steel pipe American Piping ProductsWelded vs. seamless steel pipe As industrial applications have evolved and grown more complex, the piping products and systems that serve them have had to keep pace. While many pipe manufacturing methods exist, the most prominent discussion in the industry compares electric resistance welded (ERW) vs. seamless (SMLS) steel pipe.
Welded steel pipe is one of the most important product for Metallica, with all our inventory largely comprising of carbon steel and mild steel welded pipes. Given our extensive sourcing and selling expertise we sell over 50-80 tons of welded steel pipes every day in Mumbai. Our customers comprise of end users as well as traders in 50/50 ratio. What is EFW steel pipe - pipelinedubaiEFW steel pipe (Electric Fusion Welding 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. EFW steel pipe is formed by rolling plate and welding the seam.
