An Investigation on the Longitudinal Cracking of Electric

May 23, 2020 · This study focuses on longitudinal cracks created within the weld seam of electric resistance welded steel pipes, after quenching and tempering processes. Results of the structural examinations conducted by utilizing optical microscope, energy-dispersive spectrometer equipped scanning electron microscope and X-ray diffractometer suggest that manganese silicate-type complex Difference between helical welded pipes and longitudinal Helical Welded Pipes and Longitudinal Welded Pipes. Welded line pipes enjoy a wide acceptance in oil and gas transporting market for its selection variety and relatively low cost. According to the different welding seams, welded line pipes can be further categorized into two types, the helical welded pipes and longitudinal welded pipes. Differences Between SAW and ERW Pipe Winsteel GroupAs the name suggests, SSAW has a spiral weld seam. And LSAW has a longitudinal weld seam. ERW pipe means Electric Resistance Welded pipe. Second Differences Between SAW and ERW Pipe We Will See It From The Weld Seam. The surface quality is very important for pipes. Though both SAW and ERW pipes all have a weld seam.

Differences between ERW Steel Pipe and HFW Steel Pipe

Welding seam is in longitudinal. During the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond. Meanwhile with the combined pressure, the edge of the pipe billet steel melted and extruded ERW steel pipe VS LSAW steel pipe/Welded Steel PipeNov 22, 2017 · Welded steel after annealing treatment, the cold working internal stress and welding internal stress are improved, so that the straight seam ERW steel pipe with good comprehensive mechanical properties. LSAW steel pipe is made by hot-rolled steel plate as raw materials and doing longitudinal welded in the high-frequency welding equipment. In Electric Resistance Welded - an overview ScienceDirect 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 [4].The selective and localized corrosion prefers to

Final Summary Report and Recommendations for the

Recommendation P-09-1 on the safety and performance of ERW pipe, which called on the PHMSA to conduct a comprehensive study to identify actions that can be implemented by pipeline operators to eliminate catastrophic longitudinal seam failures in ERW pipe.
