Spiral welded pipe is an alternative process, spiral weld construction allows large diameter pipe … Straight seam welded pipe has simple production process, high production efficiency, low cost and rapid development. length of the weld metal, the wrong side of the steel pipe surface, delamination, inclusions, weld defects found. Address: 22nd Floor, Royal Wing Tower, Long
In the past, due to the method of manufacture, Spiral Welded pipe was relegated to low pressure and structural applications. Longitudinal production process is simple, high production efficiency, low cost, rapid development. B. When the spiral weld near the defect with parallel, spiral weld force is smaller, so the risk of expansion not as good as straight weld large. Longitudinal welded pipe has simple production process, high production efficiency, low cost, and rapid development; spiral welded pipe generally has higher strength than longitudinal welded pipe, and can produce welded pipes with larger diameters from narrower blanks, and also can use blanks with the same width We produce welded pipes with different pipe diameters. Welded pipes are cheaper with compared to the seamless pipe and also Weak due to the weld. The T-shape weld welding residual stress and weld metal are often in a three-dimensional stress state. in accordance with the provisions of the spiral welded pipe production standard, spiral welded steel pipe inspection / control items include: determination results, the fatigue strength of the spiral welded pipe and seamless pipe and resistance welding pipe the same test data and seamless pipe and resistance tube located in the same district, rather than the submerged arc straight seam welded pipe is higher. It can use the narrow band steel to produce steel pipe with large diameter. Steel pipe production, however, only the project part, taking into account the overall project quality, project cost and other factors, spiral welded pipe still has the overall advantage. Welded pipe enjoy a wide acceptance in oil and gas transporting market for its selection variety and relatively low cost. We had heard pipelines use the 10 and 2 rule so if one of the seams burst the pressure won't push the pipe out of the ground. Stronger than other pipe – Our pipe is up to 20% stronger than smooth pipe systems of the same gauge, due to the added spiral reinforcement. Tianjin Xinyue Steel Group main prodects:ASTM A252 Spiral Steel Pipe,ASTM A106 GR B Carbon Steel Pipe,API 5L GR B Seamless Steel Pipe,ASTM A53 GR B Black Steel Pipe,HELICAL WELDED STEEL PIPE,Longitudinal Submerged Arc Welded steel Pipe. These processes are briefly described below. The steel pipe is mainly divided into a seamless steel pipe and a welded steel pipe, and the welded pipe is formed by bending a steel plate or a steel strip and then welded.. Dimensions: steel pipe outside diameter, wall thickness, ovality, the curvature of the pipe end perpendicularity. consider the requirements for pipe installation and construction, steel processing, continuity and consistency of the shape geometry is particularly important. In the common sense, the coil alloy content is often lower than similar grade steel, which also improves the weldability of the spiral pipe. SAW pipe means Submerged Arc Welded pipe.

Blasting tests also shows spiral welded pipe blasting the mouth of the circumferential deformation rate was significantly greater than the Longitudinal This confirmed that the plastic deformation of the spiral welded pipe than Longitudinal, blasting the mouth is generally confined to a pitch, spiral weld the expansion of the gap from the strong constraints. Seam welded pipe production technology is simple with high production efficiency, low cost and rapid development. Spiral pipes are specially treated. This is the main reason for the spiral welded pipe market price is higher than the Longitudinal For the composition of the steel pipe sales price, the price of materials is the dominant or even the decisive factor. This results in the weld length being 30-100% longer than that of a straight seam welded pipe. The strength of the spiral welded pipe is generally higher than straight seam welded pipe, and can adopt a narrow billet to produce larger diameter welded pipes, and it can also use the billet with the same width to produce the different pipe diameter welded pipe. Spiral Seam: Spiral seam welded pipes are manufactured when hot-rolled strip steel is formed into a pipe through spiral bending and welded along the then spiraled seam of the pipe. Spiral welded pipe or Helical welded pipe is cold formed from hot rolled coil and submerged arc welded in a single, continuous process. pipe to withstand the internal pressure, usually in the wall on the two main stress, radial stress δY and axial stress δX. are many to be found if you want to use one of them for your project. Current is passed between the two edges of the 1. Seam welded steel pipe in the form of divided Longitudinal and spiral welded pipe. WT = Seamless < Spiral Welded Pipe < Longitudinal welded pipe Length = Seamless has the nominal length between 6 meter and 12 meter only. The welding process of spiral tube, straight seam steel pipe welding methods are varied from the previous process. It has a smooth interior for low friction loss with the grooved seam entirely on the outside.
