Duplex steel pipe fittings are corrosion-resistant materials that connect parts of a duplex steel pipe system. They provide superior strength and excellent corrosion and erosion resistance, making them ideal for harsh environments. These materials are commonly found in oil and gas, chemical, marine, and other industries because of their durability and reliability.

We offer These Duplex Steel Pipe Fittings as per DIN, ISO, JIS or ANSI Standard.
Duplex Steel Pipe Fittings applications are as diverse as the industries they serve driven primarily by the aerospace, railway, construction and automotive industries with petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
Duplex steel pipe fittings are available in various configurations, such as elbows, tees, reducers, couplings, crosses, and caps. Elbows are used to change the flow direction, tees for branching connections, reducers for size reduction, couplings for joining pipes, crosses for four-way connections, and caps to close off the ends of pipes. These diverse configurations offer flexibility in designing and building piping systems to meet specific industrial requirements.
Yes, Duplex Steel Pipe Fittings are suitable for high-temperature applications. They provide excellent strength and corrosion resistance, making them ideal for environments dominated by high temperatures and harsh conditions.
When selecting Duplex Steel Pipe Fittings, key considerations include operating conditions like temperature and pressure, material quality ensuring strength and corrosion resistance, adherence to size and configuration requirements for proper fit, compliance with industry standards for safety, reputation of the supplier for quality assurance, and balancing cost with long-term value for a cost-effective choice.
Duplex steel pipe fittings are inherently corrosion-resistant due to their composition, but in certain aggressive environments, additional corrosion protection coatings may be recommended for enhanced longevity and performance. These coatings can provide an extra layer of defence against specific corrosive substances or conditions, ensuring the fittings maintain their integrity over extended periods of use.
