 Surface of LSAW Steel Pipe 

Bare, Lightly Oiled, Black/Red/Yellow Painting, Zinc/Anti-corrosive Coating


 Packing of LSAW Steel Pipe 

 Bundled/In Bulk, Plastic Caps Plugged, Waterproof Paper Wrapped


 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.
