Octal supply API 5L welded (ERW, EFW, LSAW, SSAW) steel line pipe in Gr B, X42, X46, X52, X56, X60, X65, X70, X80 PSL1, PSL2 and for sour service (NACE pipe).Line pipe brief introduction. API 5L steel line pipe is for oil and gas industries pipelines, developed for different working environments. ASTM A53 ERW Steel Pipe Inspection Process - Industry TodayCut about 100mm welded pipe and place it on a conical top core; place the conical top core under the hydraulic press, start the oil pressure, slowly press the welded pipe down, and when the flaring is 8%, check whether the weld is cracked. If there is no crack, weld the seam; if there is crack, adjust the welding process parameters in time. 3.

Difference Between Seamless And Erw PipeThe welded seam of electric weld pipe is heat-treated after welding to a minimum temperature of 1,000°F or processed so that no untempered martensite remains. Such differences of erw are usually eliminated if the electric-weld tubing is heat-treated by the quenched-and-tempered process, which is mandatory for API grades L80, C90, T95, and P110.
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. ERW Pipe Manufacturing Process - Permanent SteelERW Pipe Manufacturing Process. ERW pipes are manufactured starting from steel coils, that are at first uncoiled, cut, processed, welded, and tested as shown in the picture below. The most common welding technique used for oil and gas pipes is the so-called high-frequency induction technology (ERW-HFI), consisting in the application of an ERW Steel PipeB) Good mechanical properties.As the ERW steel pipe with easy control of rolling, with the welding technology and on-line heat treatment technology, the performance of the weld can be controlled, so straight seam welded steel pipe elongation than seamless steel pipe 8% -10% higher, which Is because the straight seam electric-welded pipe carbon content of less than 12% lower than the seamless tube.

Steel pipe, using the high frequency electric welding process (EW), is manufactured by Hall Longmore to a diameter ranging from 219 mm (8,58 inch) to 610 mm (24 inch). Wall thickness:4,5 mm to 12,7 mm. Steel Grades . The ERW manufacturing process features state-of-the-art in-line quality monitoring stations at each stage of production. Welded Pipe Production Line - Straight Welded Pipe We have been specializing in the design, development, manufacturing, and supplying of ERW pipe making machine, precision pipe mill, slitting line, and more since 2000. For example, we have successfully developed 20-660 high frequency straight welded pipe production line, LW100-LW2200 multi-functional cold rolled section steel / welded pipe production line, ZJ100-ZJ2200 slitting line What is ERW steel pipe - pipelinedubaiERW Pipe Manufacturing Process (ERW) Electric resistance welded pipe is 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.
