Duplex pipe fittings
Custom Duplex Pipe Fittings Fabricator
Duplex pipe fittings are made from the renowned material DSS, which contains a combination of austenitic and ferritic steel en pipe elements. Project engineers usually prefer this SS pipe over other materials for their amazing corrosion resistance, high strength, and toughness.
Project engineers employ DSS pipe fittings as a reliable pipe connector to connect and control fluid flow in all kinds of piping and plumbing fitting systems. These pipe & pipe fittings usually include elbows, tees, reducers, couplings, and flanges among others.
Duplex elbow manufacturer in India

Know the Range of Duplex Steel Pipe Fittings
The DSS elbow is a fitting used to change flow direction in a piping system. A DSS tee has a T-shaped design that lets fluids branch off in different directions, functioning as a versatile pipe connector across pipework fittings assemblies.
DSS reducer is a fitting used to connect pipes of different sizes. Caps and plugs, including a stub end for lap joint assemblies, are DSS fittings used to close or terminate the end of a pipe.

Can You Use Duplex Fittings in Both High-Heat and Sub-Zero Applications?
DSS pipe fittings sturdily maintain their mechanical strength and integrity without deformation in high-temperature applications. They exhibit good creep resistance, meaning they withstand prolonged exposure to elevated temperatures.
DSS retains its toughness and ductility and withstands low temperatures without becoming brittle. This is why industries such as liquefied natural gas processing and refrigeration systems highly prefer this steel en pipe material for their piping and plumbing fitting needs.

Pressure rating of duplex steel fitting

What is the maximum pressure rating for DSS fittings?
Typically, DSS fittings are available in pressure ratings ranging from 3,000 psi to 9,000 psi for small fittings. For large-sized DSS buttweld fittings such as flanges, pressure ratings can extend beyond 10,000 psi. Contact the DSS pipe fittings manufacturer in India for accurate, application-specific ratings.
Top Benefits of Duplex Stainless Steel Pipe End Caps
A DSS end cap exhibits sturdy resistance to a wide range of corrosive environments including chloride-containing solutions, acids, and alkaline solutions. DSS usually displays higher strength than austenitic ss pipe grades and other alloys.
By using DSS end caps, the overall service life of the piping system can be extended. DSS has good fatigue resistance, crucial for dynamic or cyclic loading conditions in any pipework fittings layout.
What surface finishes are available for duplex steel pipe fittings?
We are a duplex steel buttweld fittings supplier, and our DSS fittings can be finished using various surface treatments to meet requirements and enhance performance. Pickling removes impurities, scale, and oxides from the surface using acid solutions. Passivation is a subsequent treatment that creates a protective oxide layer, improving corrosion resistance across every steel en pipe fitting we supply.
