Malik Tube Fittings is a well-respected manufacturer and supplier based in Riyadh, Saudi Arabia, specializing in high-performance Hastelloy BSP and NPT fittings designed for critical fluid handling and process applications. Crafted from top-quality Hastelloy alloys, these fittings boast exceptional resistance to strong oxidizers, reducing agents, and harsh chemical environments. With secure threaded connections, both BSP (British Standard Pipe) and NPT (National Pipe Thread) fittings guarantee leak-proof performance, even under high pressure and extreme temperatures. Malik Tube Fittings provides precision-engineered solutions that adhere to global quality standards, making our Hastelloy BSP and NPT fittings perfect for the chemical, petrochemical, marine, and pharmaceutical sectors.
Hastelloy BSP and NPT fittings are made from nickel-molybdenum-chromium alloys, enhanced with elements like iron and tungsten, which give them remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. Their unique chemical makeup ensures they remain durable in both oxidizing and reducing environments. On the mechanical side, these fittings showcase impressive tensile and yield strength, toughness, and ductility, even in high-pressure and high-temperature situations. The precision threading guarantees accurate dimensions and leak-free connections, while their corrosion resistance prolongs service life, ensuring reliability in demanding environments such as chemical processing, offshore systems, and industrial piping networks.
