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 methodSee more on octgproducts helical welding pipe Decoiling
How is a spiral welded pipe weld done?
The welding system welds the pipe, first along the inside diameter and then along the outside diameter, using a submerged arc welding process. Once the welding is complete, the finished pipe is visually inspected by Quality Control (QC) and, if required, Ultrasonic (UT) testing is performed to ensure the weld is defect-free.See all results for this questionHow is helical welding used to make pipes?Thus, helical welding can be used to manufacture pipes of different diameters. It can use narrower steel to manufacture pipes into large diameter using large helical angle.See all results for this questionModelling of Spiral-Welded Pipe Manufacturing and its helical welding pipe DecoilingIn this study, X80 line pipe produced using the UOE and spiral welding processes were compared. The UOE process provides some degree of work hardening resulting from cold expansion.Estimated Reading Time: 13 mins
STANDARD SPECIFICATION FOR SUBMERGED ARC
8.3.3 The steel used for manufacture of pipe shall be fully killed and fine grained with ASTM grain size number 7 or finer as per ASTM E 112. 8.4 Tack welds 8.4.3 Tack welds shall be made by a continuous process only. Any repair in tack welds shall be (New) performed before start of Submerged Arc Welding (SAW) of seam. 8. 6 Weld seams in SAW pipeSpiral Tube/Pipe Making Machine, Spiral Welding Pipe Large horizontal spiral accumulator is the latest equipment indispensable to ensure the automatic production of high-frequency straight seam welded pipe. It plays a role in storing and feeding materials and ensuring the continuous work of the main rolling mill. The number of material storage loops in the accumulator is fixed.Ratings: 32Brand: Hangzhou Roll Forming Technology Co.,LtdSpiral Welded Pipe - Nucor SkylineThe difference is the coil is wound at an angle, so the weld runs around the outside of the pipe in the shape of a helix. This allows for more variation in diameter and thickness than Electric Resistance Welded (ERW) pipe. Spiralweld pipe is most commonly used for pipe diameters between 24 in. and 120 in. and for wall thicknesses of 1.0 in. or less.

The effect of spiral cold-bending manufacturing process on helical welding pipe Decoiling
Jul 01, 2019 · Throughout the forming process (decoiling, spiral forming) all material parameters (stresses, strains) are recorded, and their final values (including pipe hydrotest to be described in detail in the next section) are used as initial stress/strain conditions for the finite element models employed for simulating the structural performance of the pipes described in detail in Sections 3 and 4. Note that hydrotest is an essential part of the linepipe production process at the pipe Cited by: 1Publish Year: 2019Author: G. Chatzopoulou, G.C. Sarvanis, S.A. Karamanos, S.A. Karamanos, E.

What's the difference between helical welding and longitudinal welding?
Once the steel is cut for rolling, it cannot be changed, which means the diameter of the longitudinal pipe is fixed. While for helical welding, it can achieve various diameters of pipes by rolling the steel plate with different angles. Thus, helical welding can be used to manufacture pipes of different diameters.See all results for this questionWhich is helical welding seam bears the least stress?Since the radial stress is the largest stress exposed on the pipe, the vertical welding seam of longitudinal pipes withstand the most stress, circumferential welding seam bear the least stress, the helical welding seam in the middle.See all results for this question
