Product Advantages of LSAW Steel Pipe

(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.
