May 16, 2018ERW steel pipe manufacturing process includes HFW. ERW have low, medium, high-frequency welding processes. And HFW are especially for high-frequency electric resistance welding. ERW and HFW do not have very big different. Because EFW is a type of ERW process for ordinary and thin-wall thickness steel pipes. We could see its differences as below. Definition For ERW Steel Pipe and HFW Steel Pipe(plate) How does the HFW process work on steel?How does the HFW process work on steel?HFW process is to use the skin effect to concentrated on the steel object surface, use proximity effects to control the position and the power of the high-frequency electric current flow path. Since the speed is very high, the contacted plate edge could be heated and melted inshore time, then extruded through the docking process.Differences Between ERW Steel Pipe and HFW Steel Pipe HFW Carbon Steel Pipe ERW Touch of Silver

Oct 28, 2020It includes contact welding and induction welding. DC welding is usually used for small diameter steel pipes. Generally, HFW is one of ERW production methods, which uses high-frequency welding technology. Therefore, ERW steel pipe includes HFW steel pipe. Tips ASTM A53 covers seamless and welded steel pipe with nominal wall thickness. The surface (plate) Differences Between SAW and ERW Pipe Winsteel Group(steel) LSAW pipe weld seam. And the weld seam of the SAW pipe is not flat. You will see the weld seam of the LSAW pipe and SSAW pipe is higher than the steel plate. And the tolerance of weld seam height specified in specifications. If compare ERW pipes with SAW pipes, ERW pipes surface quality is better. ERW pipes are smooth and have a better finish.

Galvanized ERW Steel Pipe Advantage. Galvanized steel pipe features a protective zinc coating that helps prevent corrosion, rust, and the buildup of mineral deposits, thereby extending the pipes lifespan. Galvanized steel pipe is most commonly used in plumbing and other water-supply applications.(plate) Heat-treating line pipe weld seams - The Fabricator(steel) Why Heat-Treat Weld Seams?2D Numerical AnalysisLine Layout and Seam TrackingSimulation VerificationDuring high-frequency welding, the outer and inner sides of the pipe wall experience the highest temperatures. This creates a heat-affected zone (HAZ) with a characteristic hour-glass shape. The heat also changes the tensile properties of the HAZ, reducing its toughness (its ability to absorb an impact without rupturing). Weld-seam heat treatment re-establishes the tensile properties of theHAZ, bringing them back to levels equal to those of the base material. HoweverSee more on thefabricatorWhat is EFW steel pipe - pipelinedubai(steel) Materials of EFW steel pipe. Pipes made from carbon steel lose strength at high temperatures. Electric-resistance-welded pipe is not considered satisfactory for service above 750 F, whereas furnace-buttwelded pipes are not good above 650 F. For higher temperatures, pipe made from stainless steels or other alloys should be considered.
