Apr 03, 1993 · Dimitris I. Pantelis, Theodora E. Tsiourva, in Trends in Oil and Gas Corrosion Research and Technologies, 2017. 10.2.2.1 Case studies. Preferential corrosion attack in the weld area, leading to premature leaking, was observed in electric resistance welded (ERW) of carbon and low alloy steel pipes exposed to neutral salt-containing waters .The selective and localized corrosion prefers to Examining electric resistance weld nuggets in tube and pipeTypes of pressure-application tube and pipe are cross-country line pipe, such as API 5L grades for the transmission of oil and gas; down-hole casing for oil and gas wells; and pipe used in oil and gas refineries. This article focuses on the fundamental steps required for any manufacturer to High-frequency electric resistance welding:An overviewHF ERW:A History. Electric resistance welding was modified and improved in the 1950s by Thermatool's Wallace Rudd. Rudd developed high-frequency welding and, in doing so, solved some of the inherent process limitations of DC welding and low-frequency welding, such as excess heat and low weld

ERW pipe manufacturing process includes HFW. ERW have low, medium, high frequency welding processes, and HFW is especially for high-frequency electric resistance welding. Types of Oil & Gas Pipes:Seamless, ERW, LSAW Dec 20, 2018 · 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 induction current on the outer surface of the pipe able to generate a robust seam weld and join the two sides of the steel
How to identify seamless pipe and welded pipe Seamless steel tubes have a hollow cross-section and are used in large quantities as pipes for transporting fluids, such as pipes for transporting oil, na. Specification Octal offers various of carbon steel pipes including seamless, welded (ERW EFW, LSAW, SSAW) steel pipes for the mining industries. What is EFW steel pipe - pipelinedubaiAPI 5L :Line Pipe. In the oil and natural gas industries, steel pipe used to convey oil and gas is manufactured to the American Petroleum Institutes standard API 5L, which applies tighter control of composition and more testing than ASTM-120.
