Super Duplex BSP/NPT fittings are constructed from high-alloy stainless steel, generally containing 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and nitrogen for greater strength and corrosion resistance. These fittings have very good mechanical properties, such as tensile strength of approximately 800 MPa and a yield strength of approximately 550 MPa. They have high impact toughness even down to sub-zero temperatures, as well as excellent resistance to stress corrosion cracking, pitting, and crevice corrosion. Their duplex structure ensures a well-balanced combination of ductility and strength, and therefore they are best suited for high-pressure corrosive environments.

Super Duplex BSP / NPT Fittings Uses

Super Duplex BSP/NPT fittings are widely applied in high-strength and corrosion-resistant applications under harsh conditions in various industries. In the petroleum and gas industry, they are used in offshore platforms, subsea piping, and drilling facilities. Chemical and petrochemical plants use these fittings for dealing with aggressive fluids and corrosive chemicals. In marine applications, their ability to resist corrosion due to chloride makes them suitable for shipbuilding and seawater systems. Moreover, they find application in power generation plants, heat exchangers, and desalination plants. Due to their versatility and durability, they are also ideal for high-pressure hydraulic and instrumentation systems.
