Corrosion Resistance ASTM 53 ASTM A500 LSAW Steel Tube

Out Diameter : 762mm - 1219mm ( 30 "- 48 " ) Dredging LSAW Steel Pipe

LSAW steel tube (Longitudinally Submerged Arc Welding, abbreviated as LSAW) is a professional expression term for straight seam submerged arc welded steel pipe.

The LSAW steel pipe is produced by using a single plate as a raw material, pressing (rolling) the steel plate into a tube blank in a mold or a molding machine, and adopting double-sided submerged arc welding and expanding the diameter. The finished product has a wide range of specifications, and the weld has good toughness, plasticity, uniformity and compactness, and has the advantages of large pipe diameter, thick pipe wall, high pressure resistance, low temperature resistance and corrosion resistance.

Dredging is an underwater excavation project for dredging, widening or digging deep water areas such as rivers and lakes.

After years of development, China has become the world's largest dredging country, with an annual dredging volume of more than 1 billion cubic meters. China has become one of the few countries in the world that have mastered cutting-edge dredging technology and can independently carry out large-scale dredging projects of land dredging and waterway dredging.
