LSAW in leaflets plate as raw material, the steel plate in the mold or molding machine pressure (volume) into using double-sided submerged arc welding and flaring from production. A wide range of the finished product specifications, weld toughness, ductility, uniformity and dense, with a large diameter, wall thickness, high pressure resistance, low-temperature corrosion resistance, etc… Today, let’s have a topic on the advantages of LSAW steel pipes.
Advantages of LSAW steel pipe are:
(1) without the unwind process, the base material indentation, scratch less.
(2) the wrong side, slotted, and other easy-to-diameter perimeter control, excellent welding quality.
(3) the elimination of flaring basically does not exist residual stress after stress.
(4) because it is a straight line weld, the weld is short, little risk of defects.
(5) after expanding, pipe geometry accuracy is improved greatly facilitate the on-site welding.
(6) for a straight seam, less impact on the quality of anti-corrosion coating materials.
