For large diameter welded pipes, double welding method can be accepted. Seamless Tube Manufacturing Process. Seamless tubes are generally made in complex steps starting with the drilled hollows from billets, by cold drawing and cold rolling manufacturing process with cold drawing & cold rolling machines. Difference between helical welded pipes and longitudinal As for longitudinal welded pipes, to meet the required length of pipelines used in industry projects, short longitudinal pipes always need to be jointed and welded into a long enough pipe. Thus, inevitably, many T-shaped welding seams would appear in this welding process, largely increasing the possibility of welding defects.
Therefore, helical welded pipe manufacturing, with complicated welding method, is more time-consuming. As for longitudinal welded pipes, to meet the required length of pipelines used in industry projects, short longitudinal pipes always need to be jointed and welded into a long enough pipe.

Longitudinal Submerged Arc Welded Pipe LSAW Pipe Jun 30, 2018 · LSAW steel pipe, a type of longitudinally welded steel pipe produced by using the double-sided submerged arc welding method. LSAW steel pipe is welded tubular products made out of flat plates that are formed, bent and prepared for welding. LSAW is welded with a straight seam that runs lengthwise across the pipe.
Longitudinal submerged arc welded (LSAW) pipes manufacture process is bending and welding wide steel plates to pipes from leveled hot rolled coils by both the JCOE and UOE (the forming process in which the plate like the letter "J", "C", "O" or "U" shape, then expansion) forming processes. Longitudinal Welded Pipe for Water Transmission Pipeline UOE is a method used for production of longitudinally welded large diameter pipes. Longitudinal edges of steel plates are first beveled using carbide milling equipment. Beveled plates are then formed into a U shape using a U-press and subsequently into an O shape using an O-press.
Mainly as a field gathering pipe and internal high-pressure natural gas pipeline of small-caliber, long-distance pipelines for oil and gas a small number, the vast majority of long-distance pipeline is the use of high-frequency straight seam welded pipe (ERW), spiral submerged arc welded pipe (SSAW), LSAW steel pipe (LSAW) three. Longitudinally welded ::TMKLongitudinally welded Longitudinally welded large-diameter pipes are intended for construction of oil and gas main pipelines, field oil pipelines, general-purpose
Steel pipes still have the main roll in petrochemical industry. Submerged Arc Welding (SAW) process could be treated as one of the most important processes for obtaining longitudinally welded steel pipes, mainly due to the very good quality of welded joints and high productivity. However the defects in welded joints often lead to damage of installations and even more dangerous human victims 1-3 . Offshore Application of HFI-Pipes Production and High Frequency Inductive (HFI) welding is a highly productive process for the fabrication of longitudinally welded pipes from hot rolled strip.

Preamble Spiral pipe (helically welded pipe) has been produced industrially in the U.S. since 1888. Production technology for longitudinally welded and helically welded pipe developed more or less in tandem, but somewhat staggered in time, which resulted in some pipe being applied in operations for which they were not produced. The Role of Solution Treatment of LSAW Steel PipeUsually divided into metric electric welded steel pipe, electric welded thin-walled pipe, transformer cooling oil pipe and so on. Longitudinal welded pipe has simple production process, high production efficiency, low cost and rapid development. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. A narrower blank can be used to produce welded pipes with larger pipe
