What's the difference between welded and seamless pipe?What's the difference between welded and seamless pipe?Welded pipe can be manufactured in large size without any upper restriction. Welded pipe with filler material can be used in the manufacturing of long radius bends and elbow. Welded pipes are cheaper with compared to the seamless pipe and also Weak due to the weld There are different welding methods used to weld the pipe.Pipe Manufacturing Process / Methods for Seamless & Welded Pipe

Which is better longitudinal or helical welding for pipes?Which is better longitudinal or helical welding for pipes?It can use narrower steel to manufacture pipes into large diameter using large helical angle. But for pipes of the same length, the helical welding seam is 30 to 100% longer than the longitudinal welding seam, thus, the welding cost is higher and the welding efficiency is lower.Difference between helical welded pipes and longitudinal longitudinal seam welding pipeAs the name shows, longitudinal pipe has astraight welding seam on the pipe surface. Different from the longitudinal pipe, the welding seam of which is vertical to the axial line of the pipe, helical welded pipe is rolled and welded according to certain helical angles.Difference between helical welded pipes and longitudinal longitudinal seam welding pipe

Was this helpful?Why do longitudinal welded pipes have T shaped seams?Why do longitudinal welded pipes have T shaped seams?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.

Difference between helical welded pipes and longitudinal longitudinal seam welding pipe

in Manufacturing and Welding Aspectsin Strength Tolerancein Terms of Various Diameters of PipesComparatively speaking, longitudinal welded pipe has simple manufacturing and welding techniques. As the name shows, longitudinal pipe has a straight welding seam on the pipe surface. Different from the longitudinal pipe, the welding seam of which is vertical to the axial line of the pipe, helical welded pipe is rolled and welded according to certain helical angles. Therefore, helical welded pipe manufacturing, with complicated welding See more on octgproductsLongitudinal weld seam on piping. - American Welding SocietySep 25, 2005The pipe rips open longitudinally until the tear comes to about 2" or 3" from the weld and then makes a 90 degree turn and tears parallel to the weld seam for another foot or so. I'm always suprised to see it as I would think the failure would be progressing with enought velocity and ferocity to continue right through the weld without even noticing.Differences between ERW Steel Pipe and HFW Steel PipeWelding 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.Electric Resistance Welded - an overview ScienceDirect longitudinal seam welding pipeIt is now generally considered that longitudinal corrosion across seam welds (other than autogenous a welding procedure that does not use filler metal such as electric resistance welded line pipe) can be treated as corrosion in parent plate (i.e. as though the corrosion is in the line pipe), and this is supported by test data (e longitudinal seam welding pipe

Introduction to Welded Pipe Manufacturing - The Process

Electric Resistance Welding (ERW) ProcessSubmerged Arc Welding (Saw) ProcessElectric Flash Welding ProcessLap Welding ProcessIn Electric Resistance Welding (ERW) process, pipe is manufactured by cold-forming a flat sheet of steel into a cylindrical shape. Then current is passed between the two edges of the steel cylinder to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material. Several Electric Resistance Welding (ERW) processes are available for pipe production. The two main types of ERW are 1. See more on theprocesspiping 6 minsPipe Manufacturing Process / Methods for Seamless & SAW Pipe Manufacturing Process. In the SAW welding process, external filler metal (wire electrodes) are used to join the formed plates. SAW pipes can have a single longitudinal seam of double longitudinal seam depend on the size of the pipe.
