　　Size deviation mainly in the SSAW steel pipe is straightness, roundness, aspects of uneven thickness. 　　In most cases, straightness tolerance for the use of spiral steel pipe under large, but the manufacturing standards for spiral pipe straightness requests, if the predetermined value is exceeded, would constitute a reason to return, and therefore, spiral pipe plant should still be noted. Roundness tolerance will affect the use of spiral steel pipe, mainly in the group of the wrong side of the welding head. Roundness tolerance has led to the wrong side of the welded joint will not only reduce the pressure capability, but also stress concentration. When the site Group, roundness some pipe can be corrected. Outside diameter deviation and the impact on the spiral steel pipe used roundness tolerance fairly. 　　Non-uniform wall thickness generally easy to be ignored, and many spiral steel pipe standards are not clearly defined. If the wall thickness Uneven, it will not only result set...

　　Longitudinal Submerged Arc Welded Pipe or simply LSAW steel pipe and Straight Seam Submerged Arc Welded Pipe or simply SSAW steel pipe belong to submerged-arc welding (SAW). But LSAW steel pipe adopts single steel sheet as raw material, its advantages include: the thickness of the steel plate can reach more than 100mm, and there is no crescent bends; since it is straight seam, forming is more convenient, but also it is easy to weld tracking, which is suitable for two-step pre-precision welding production; and there is the whole body of mechanical expansion process, which can basically eliminate the residual stress. All of advantages above make LSAW can be produced big diameter steel pipe (the maximum can reach 1422mm), high-grade pipe (50mm), high steel grade (X80/X100/X120), and large structure tube that used in two, three, four types of regional and marine engineering. LSAW steel pipe and high-frequency Longitudinal Welded Pipe (HFW steel pipe) all belong to Longitudinal Welded Pi...

　　The main differences between SSAW and LSAW steel pipes are in their length and pattern of welding seam. SSAW pipes have longer welding seams than LSAW pipes and so have a higher risk of seam defects. Meanwhile, for SSAW steel pipes, the welding seam is at a certain angle with the orientation of the priciple stress. This shortens the faulty welding joints of an SSAW steel pipe when compared with an LSAW steel pipe of an equivalent length. (This reduces the danger of a single defect). The disadvantage and advantage mentioned above cancel out each other. The difference between the orientation of the welded seam and the special directivity often major raw material of a SSAW steel pipe enhance its resistance against fracture. 　　In 1998, the Tubular Goods Research Center of CNPC, together with China Petroleum Planning and Engineering Institute conducted a comparative experiment systemically on domestically produced SSAW steel pipes and imported LSAW (UOE) steel pipes. 　　The following ...

    For the ssaw steel pipe , although the result of the tensile test specimens substantially independent of sampling direction, but the test results v Charpy impact specimen was closely related to the sampling direction. When sampling along the rolling direction CVN maximum value when the vertical direction of rolling sample CVN value of the minimum.     The difference between the ssaw and lsaw steel pipe on rupture is that the latter is consistent initiation or expansion maximum driving direction of least resistance (are axially), thus initiation and expansion must be carried along to uranium. But on the contrary, spiral initiation or expansion of the maximum driving direction (to oil) and the path of least resistance (the rolling direction) are inconsistent, so the crack initiation and propagation direction there are two possibilities; one axial vent; two along the rolling direction (ie, spiral weld direction).     The ratio is generally considered t...
