Chanathip Nickel Alloys & Plates is a reliable manufacturer of Duplex 2205 tube fittings in Bangkok, Thailand. Our broad range includes compression tube fittings, ferrule fittings, tube-to-pipe connectors, and instrumentation fittings built to international specifications. Made from high-quality Duplex 2205, these fittings provide excellent corrosion resistance, pressure handling, and dimensional accuracy. They are designed for seamless tube systems suitable for oil and gas, desalination, power generation, and chemical processing industries. Each product is tested for leak-proof sealing, mechanical integrity, and compliance with material standards, ensuring reliable performance in aggressive and high-stress conditions.
Duplex 2205 tube fittings contain about 22% chromium, 5–6.5% nickel, 3% molybdenum, and up to 0.20% nitrogen, with low carbon levels. This results in a balanced austenitic-ferritic microstructure. The fittings achieve high tensile strength up to 700 MPa, yield strength around 450 MPa, and elongation of 25% or more. They exhibit excellent resistance to pitting (PREN ≥35), stress corrosion cracking, and fatigue. With hardness below 290 HB, Duplex 2205 ensures long-lasting stability and mechanical strength in harsh conditions. The alloy suits both cryogenic and high-temperature applications in pressurized tube systems.

Duplex 2205 tube fittings are perfect for pressurized instrumentation lines, fluid transport systems, and chemical injection systems. They are commonly found on offshore platforms, marine vessels, power plants, and desalination facilities. These fittings are essential in environments containing chlorides, sulfides, and other aggressive chemicals. Their high strength allows for thinner walls, reducing system weight without losing performance. They connect tubing in compact control panels, process skids, and analyzers, providing reliability, leak resistance, and corrosion durability. Duplex 2205 fittings help lower lifecycle costs and increase system efficiency.
