Our ultra long welded stainless steel coiled tubing is engineered for high-performance oilfield and offshore applications. Unlike traditional coiled tubing with orbital welds or multiple sections joined together, our coils are produced in one continuous piece — no pipe-to-pipe welding at all.
Each coil can reach over 400 kilograms in weight, significantly reducing risks of leakage, improving strength, and enhancing system reliability. With over 20 years of experience, we are proud suppliers to world-renowned companies such as Baker Hughes, Halliburton, OXY, KOC, KNPC, and more.
Key advantages:
-
No orbital welds or pipe joints
-
Consistent wall thickness and high dimensional accuracy
