High-frequency welding (HFW) is a solid resistance heat energy.The use of high-frequency current welding resistance heat generated in the workpiece so that the workpiece is heated to melt the welding area or near the surface of the plastic state,then applied (or not applied) forging force and achieve a combination of metals.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).Related searches for erw carbon steel pipe hfwcarbon steel pipe specificationscarbon steel pipe supplierscarbon steel pipe price listseamless carbon steel pipe manufacturerserw carbon steel pipeerw steel pipeerw pipewhat is erw pipeSome results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextChina ERW / HFW STEEL PIPE Your reliable ERW steel pipe supplier .The company's main products are ordinary welded pipe,line pipe,structural steel pipe,rectangular steel pipe,galvanized steel pipe,plastic coated epoxy resin composite water supply pipe,etc.The annual production capacity can reach 700,000 tons.
