Jassem Tube Fittings is a trusted manufacturer and supplier based in Doha, Qatar, delivering high-quality Super Duplex Steel Hydraulic Fittings designed for demanding industrial environments. With a strong focus on precision, durability, and international quality standards, the company supports industries that require reliable fluid control under extreme pressure and corrosive conditions. Jassem Tube Fittings combines advanced manufacturing practices with deep industry knowledge to provide fittings that ensure leak-free performance, long service life, and safety. Their Super Duplex Steel Hydraulic Fittings are valued for consistent quality, excellent corrosion resistance, and dependable performance in critical applications.
Super Duplex Steel Hydraulic Fittings are made from a balanced microstructure of austenite and ferrite, typically containing high levels of chromium, nickel, molybdenum, and nitrogen. This composition provides exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. Mechanically, these fittings offer high tensile strength, excellent yield strength, and good toughness even under high pressure. The material maintains structural stability at elevated temperatures and delivers superior fatigue resistance, making it ideal for heavy-duty hydraulic systems.
