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. The series of API5L X42 Spiral Steel tube is used for oilfield and gas transmission.
Here, we discuss more about API 5L.
The exterior is treated with anticorrosion or black paint, and it is often used for spiral pipe of petroleum and natural gas pipelines. It is divided into PSL1 and PSL2. GK could offer twos.
API standard spiral steel pipe friction reduction and abrasion resistance are reflected by friction coefficient, abrasion and relative abrasion coefficient.
Spiral weld sizes are available upon request. You will find unique steel tube sizes which may not be made by other manufactures at GK Tubes because of GK professional technical team and strong technology power.
GK could offer following existing type and application of spiral steel tube for your choice.
