Product Description：
Our Stainless Steel Seamless Coil Tubing is manufactured using high-quality stainless materials such as 316L, 304, Duplex 2205, Inconel 625, and 825, offering exceptional corrosion resistance, pressure durability, and mechanical strength. Each coil is 100% seamless, joint-free, and produced under strict quality control to meet demanding applications in the oil & gas, chemical injection, instrumentation, and offshore control systems.
We provide tubing in continuous lengths up to 6,000 meters without any orbital welds. All coils are pressure tested, eddy current tested, and certified, and we offer third-party inspections (BV, SGS, DNV, TUV) upon request.
