Reliability in Corrosive Environments

Duplex steel pipe fittings deliver exceptional corrosion resistance, ideal for aggressive media and challenging environments found in industries like oil & gas and chemical processing. The duplex stainless steel grades (UNS S31803, S32205) ensure long-term durability, minimizing maintenance and downtime costs. This makes them a robust solution for fluid transfer and critical pipeline connections.

Comprehensive Testing and Quality Assurance

Each fitting goes through rigorous quality checks, including 100% radiography, Positive Material Identification (PMI), and hydrostatic tests, ensuring leak-proof performance and compliance with international standards. Precise wall thickness tolerance and adherence to ASTM A815/ASME SA815 guarantee reliability, consistent quality, and safety in demanding applications.

Customizable Design and Flexible Application

Duplex steel pipe fittings come in a variety of shapes, wall thicknesses, sizes, and surface finishes to suit project-specific needs. Available with plain, beveled, or threaded ends, and compatible with socket weld, butt weld, and NPT/BSP threaded connections, these fittings support seamless integration into new or existing pipe systems in every major industrial sector.

FAQs of Duplex Steel Pipe Fittings:

Q: How are duplex steel pipe fittings tested to ensure quality and safety?

A: Duplex steel pipe fittings undergo 100% radiography, Positive Material Identification (PMI), and hydrostatic pressure tests. These comprehensive inspections verify material integrity, wall thickness tolerance as per ASTM A815, and leak-proof performance, ensuring compliance with international standards.

Q: What are the main benefits of choosing duplex stainless steel fittings for industrial applications?

A: These fittings offer excellent corrosion resistance, high impact and tensile strength, and superior durability in harsh environments. Their leak-proof and high mechanical performance characteristics reduce maintenance needs, making them ideal for critical oil, gas, petrochemical, chemical, and marine installations.

Q: When should I use seamless versus welded duplex steel pipe fittings?

A: Seamless fittings are preferred for high-pressure and critical corrosive environments due to their uniformity and strength, while welded fittings are suitable for larger diameters or where cost efficiency is prioritized without compromising reliability.

Q: Where can duplex steel pipe fittings be utilized?

A: These fittings are designed for use in pipeline connections, fluid transfer, and process lines across oil & gas, petrochemical, chemical processing, power plants, and marine industries, especially where high strength and corrosion resistance are required.

Q: What are the available end connections and thread types for these fittings?

A: Duplex steel fittings can be supplied with plain, beveled, or threaded ends. Thread types include NPT and BSP, supporting socket weld, butt weld, and threaded connections, enabling compatibility with a wide range of piping systems.
