FeedbackDifferences between ERW Steel Pipe and HFW Steel Pipe

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. Is HFW required in API 5L PSL2 ERW steel pipe?Is HFW required in API 5L PSL2 ERW steel pipe?HFW is required in API 5L PSL2 ERW steel pipe. According the API 5L and ISO 3183 specification, for PSL 2 pipes in welded process the HFW welding is a mandatory requirements for ERW steel pipes. As it is an improvement from the inherent problems of hardness, lack of fusion and susceptibility of stress corrosion cracking (SCC).Differences between ERW Steel Pipe and HFW Steel Pipe What is the difference between ERW and HFW?What is the difference between ERW and HFW?ERW have low, medium, high frequency welding processes, and HFW is specially for high-frequency electric resistance welding. The differences between ERW and HFW steel pipe, is EFW is a type of ERW process for ordinary and thin-wall thickness steel pipes.

Battelles Experience with ERW and Flash Weld Seam SS400 erw longitudinal welded pipe

Oct 09, 2013Comprehensive Study to Understand Longitudinal ERW Seam Failures DTPH56-11-T-000003 Battelle iii September 2012 EXECUTIVE SUMMARY This report presents an evaluation of the database dealing with failures originating in electric resistance welds (ERW) and flash weld (FW) seam defects as quantified by Battelles archivesCarbon Steel Pipe - an overview ScienceDirect TopicsAs an example, a NPS 6 CS pipe with standard wall thickness (0.280) requires 6 WDIs worth of work to butt-weld, whereas a NPS 6 SS pipe with Sch. 80S wall thickness (0.432) requires in the range of 14 WDIs to butt-weld. In other words, the latter weld requires a factor of 2.3 times longer to complete.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.

Welded vs. seamless steel pipe American Piping Products

Welded vs. seamless steel pipe. As industrial applications have evolved and grown more complex, the piping products and systems that serve them have had to keep pace. While many pipe manufacturing methods exist, the most prominent discussion in the industry compares electric resistance welded (ERW) vs. seamless (SMLS) steel pipe.What is a Welded Steel Pipe? About Welded or ERW Steel SS400 erw longitudinal welded pipeWelded pipe (pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp that are formed, bent and prepared for welding. The most popular process for large diameter pipe uses a longitudinal seam weld. Spiral welded pipe is an alternative process, spiral weld construction allows large diameter pipe to be produced from narrower plates or skelp.
