Duplex steel fittings, including BSP and NPT types, typically contain about 22% chromium, 5% nickel, and 3% molybdenum for improved corrosion resistance and strength Mechanical properties include high tensile strength (up to 550 MPa), good ductility, and good fatigue resistance. These fittings are advantageous due to their ability to withstand harsh environments, making them ideal for oil and gas, chemical and marine applications Their high resistance to pitting and stress corrosion cracking ensures a long and capable life reliability, ultimately reducing maintenance costs and improving system performance.

Duplex BSP / NPT Fittings Uses
Duplex steel BSP/NPT fittings are widely used in applications requiring high strength, corrosion resistance and durability. These materials are used in pharmaceutical, oil and gas, petrochemical and marine applications, due to their resistance to harsh environmental conditions, including chloride exposure and acidic conditions Superior mechanical properties of duplex steel These fittings are high-pressure systems,. Piping and flow-control make it ideal. BSP (British Standard Pipe) and NPT (National Pipe Thread) standards ensure reliable, leak-proof connections in critical infrastructure, increasing safety and operational efficiency.
