Spiral welded steel pipe is one type of welded tubes, cold formed from hot rolled coil and submerged arc welded in a single and continuous process.
GK spiral welding process is efficient, flexible, and cost efficient based on our advanced equipment. Spiral welded tube has been widely applied for the transmission of petroleum gas, low-pressure fluid, be also used as structural member and use.
Spiral welding process is totally different with straight welding. A continuous full penetration metal inert gas weld overlay is used to rebuild or repair damage from wear, erosion, corrosion or cracking, or to enlarge the dimensions of a component on a mating part during spiral welding process. Usually, large diameter welded steel tube is made through such welding steps.
The common materials for spiral welded steel tube are as below:
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)。
