Nov 24, 2014 · 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. ERW Steel Pipe - PETROL STEELThe Main Steel Grades of welded steel pipes in our pipe mill:BS7 welded tubes, S235 S235JR welded pipes, S275 S275JR welded ERW pipe, S355JRH S355J2H welded tube ERW, St44 ST52 welding pipes ASTM A53 Gr.B HFI pipes EFW pipes API 5L Gr.B, X42, X46, X52, X56, X60, X65 X70 HFW pipes L245, L290, L320, L360, L290, L320, L360, L390, L415, L450 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.
LSAW (Longitudinal double submerge arc welding) carbon steel pipe is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology. JCOE technology represents the shaping and forming processes involved during manufacturing as well as the inner and outer welding and cold expansion carried out after welding. Manufacturing Process for Welded Pipes. How To Produce Mar 12, 2019 · In the ERW and EFW manufacturing process welded pipes are formed by hot or cold rolling plate and welding the seam. In order to keep the outside (O.D.) surface of a welded pipe smooth and uniform a cutting tool called scarfing blade is used to remove the weld flash. Scarfing from the inside (I.D.) welded flash is also possible. Pipe Manufacturing Process / Methods for Seamless & SAW- Submerged Arc Welding (Long seam & Spiral Seam) ERW Steel Pipe Manufacturing Process In the ERW / EFW / HFW pipe process, the first plate is formed in a cylindrical shape and the longitudinal edges of the cylinder formed are welded by flash-welding, low-frequency resistance-welding, high-frequency induction welding, or high-frequency
Aug 06, 2011 · Welded Steel Pipe. ERW Steel Pipe:Outside Diameter:21.3mm-660mm. Wall Thickness:1mm-20mm. Length:5.8/6/11.8/12m. LSAW Steel Pipe:Outside Diameter:406mm-1626mm. Wall Thickness:6.0mm-60mm. Length:5.8/6/11.8/12m. Stainless Steel EFW Pipe SS 304/316 EFW Pipe5 rows · Stainless Steel Efw Welded Pipe is a type of stainless steel pipes that is produced What are differences between SAW pipes and ERW pipes Haihao Group could provide many kinds of pipes made by carbon steel,stainless steel and alloy steel like weld steel pipe and seamless steel pipe.And at first in welded steel pipe,you will find different methods of forming process, such as ERW,LSAW,SSAW.So lets talk about the differences between SAW pipes and ERW pipe.
EFW 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.Stainless Steel EFW Pipe,Stainless Steel ERW Pipes 13 rows · ERW namely Electric resistance welding. prouducts:efw stainless steel pipe,efw
