2205 Coiled Tubing

Duplex 2205 coiled tubing is widely used in oil and gas, offshore, and chemical industries where both high strength and corrosion resistance are required. Compared with standard austenitic stainless steel such as 316L, Duplex 2205 provides superior resistance to chloride-induced corrosion and significantly higher mechanical strength, making it suitable for demanding environments.

In applications such as offshore platforms, subsea systems, and chemical injection lines, tubing must withstand high pressure, aggressive media, and long-term continuous operation. Any connection point in traditional tubing systems increases the risk of leakage and failure.

We specialize in manufacturing continuous Duplex 2205 coiled tubing with lengths up to 10000 meters without intermediate joints. This advanced production capability reduces installation complexity and minimizes potential leakage points, ensuring higher system reliability.

Our coiled tubing is produced using precision welding, controlled heat treatment, and strict quality inspection processes to ensure uniform mechanical properties, consistent wall thickness, and excellent corrosion resistance throughout the entire coil.

Duplex 2205 features a dual-phase microstructure of austenite and ferrite, providing excellent resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich environments such as seawater and offshore conditions.
