ERW Casing, API Steel Casing Pipe

May 14, 2021 · ERW Casing-Casing made of electric welded pipe as raw material. ERW (Electric Resistant Weld) steel pipe refers to a straight seam welded pipe manufactured through a high-frequency resistance welding process. The raw material steel plate (coil) of ERW welded pipe is made of low-carbon microalloy steel rolled by TMCP (Thermo-Mechanical Control Process). ERW Steel Pipe - PETROL STEELPETROL STEEL CO., LTD is a leading manufacturer and stockist of ERW steel pipe in China. The detailed sizes of Electric Resistance Welded steel pipes in our piping factory:Outer Diameter:6mm-610mm (1/16"-24") Wall Thickness:0.3mm-22mm. Length:0.5mtr-20mtr. ERW Steel Pipe, A53 ERW Pipe - Seamless Steel PipeElectric Resistance Welded (ERW) pipe is manufactured by cold forming a flat steel strip into a rounded tube and passing it through a series of forming rollers to obtain a longitudinal seam. The two edges are then simultaneously heated with a high frequency current and squeezed together to form a bond.

High Frequency Induction (HFI) Welded Pipe - Sunny Steel

HIGH-FREQUENCY WELDING is a welding process in which the heat source used to melt the joining surfaces is obtained from high-frequency (HF) alternating current (ac) resistance heating. The high-frequency induction (HFI) resistance pressure welding technique for longitudinal welding. The endless strip passes through rolling stands where it is shaped to an open pipe, which runs through a high Quality ERW Steel Pipe & ERW Black Steel Pipe factory from Q195 Q215 Q235 Q345 Structural ERW Carbon Steel Pipe; High Pressure 9.5mm 40mm Double Submerged Arc Welded Pipe; ASTM A252 AS1163 Saw Steel Pipe For Gas Transmission; Gas Transmission API 5L PSL2 X52M ERW Galvanised Metal Tube; Q235B API 5L PSL1 PSL2 HFW Steel Pipe For Structural Field; Anti Corrosion 32 Inch ASTM A53 GrA API 5L GrB ERW CS Pipe 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

Welded Carbon Steel Pipe, CS Pipe Manufacturer

Aug 06, 2011 · Pipe Type:ERW Pipe, ERW Steel Pipe, Electric Resistance Welded Pipe, HFW Steel Pipe, EFW Steel Pipe Application:F or Low Pressure Fluid Transmission, M achinery Manufacturing. Specification:OD:21.3mm ~ 660mm. WT:1mm ~ 17.5mm LENGTH:0.5mtr ~ 22mtr (5.8/6/11.8/12 meters, SRL, DRL) Welded vs. seamless steel pipe American Piping ProductsJul 02, 2018 · Welded pipe manufacturing techniques have improved over the years. Perhaps the most important advancement has been the switch to high-frequency electric currents for welding. Prior to the 1970s, low-frequency current was used. Weld seams produced from low-frequency ERW were more prone to corrosion and seam failure. What is a HFW steel pipe? - ugsteelmillDec 04, 2018 · The high-frequency welding for carbon steel welded pipe production has been 40 years of history. Having a large power supply power, high-frequency welding of different material, diameter and wall thickness of a steel pipe can reach a higher welding speed (highest ratio TIG welding speed is more than l0 times higher).
