Introduction:Spiral steel pipes are made from strip steel coils, formed through normal temperature extrusion, and then welded into spiral seam pipes using the automatic double-sided submerged arc welding process with double fillet welding.

Material: Q235A，Q235B、10#、20#、Q345（16Mn）、L245(B)、L290（X42）、L320（X46）、L360（X52）、L390(X56)、L415(X60)、 L450(X65)、L485(X70)、L555(X80)、L290NB/MB（X42N/M）、L360NB/MB（X52N/M）、L390NB/MB(X56N/M)、L415NB/MB(X60N/M)、L450MB(X65)、L485MB(X70)、L555MB(X80)。

Purpose:Spiral steel pipes are primarily used in water supply projects, petrochemical industry, chemical industry, power industry, agricultural irrigation, and urban construction. They are among the twenty key products developed in our country.

For liquid transportation: water supply, drainage, oil transportation.

For gas transmission: Coal gas, steam.

For structural purposes: pile pipes, bridges, docks, roads, and tubes for building structures.
