    Ovality and Bending of LSAW Steel Pipe

    In order to control the ellipticity, some lsaw steel pipe standards specify the allowable index of ellipticity, which is generally specified as not to exceed 80% of the outer diameter tolerance (executed after consultation by the supply and demand sides). LSAW steel pipe is curved in the length direction, and its curve degree is called curvature.Rising global offshore LSAW demand to tighten up pipe mill supply dn140large diameter lsaw steelNonetheless, LSAW linepipe capacity still remains high with other LSAW export focused mills in Japan, Europe and India, who specialize in the supply of sour service offshore linepipes.
