Duplex Steel Fittings

Duplex Steel Fittings

SGS Audited manufacturer of Duplex Pipe Fittings in India, We keep ready stock of Alloy 2205 S31803 Elbow and ASTM A815 UNS S31803 Reducer produce according to American standards

A duplex pipe fitting is a type of pipe connector that allows for easy adaption to other piping equipment and subsequently influence the flow of media. The Duplex Pipe Fittings are designed with an equal amount of austenitic and ferritic microstructure. These fittings have excellent chemical composition, giving them good resistance across different environments. Duplex Fittings can be shaped in the form of elbows, tees, couplings, unions, caps, valves, etc. They are designed in different sizes and shapes, making the Duplex Stainless Steel Pipe Fittings a viable option for use in desalination plants, heat exchangers, power generation, marine processes, and so on. Duplex Steel Buttweld Fittings are one of the simplest and strongest types of welded fittings. These fittings have a continuous metal structure and ensure a leak-proof connection. The 1.4462 Fittings are work hardenable alloys that work well in higher pressure and temperature conditions. The fittings have excellent performance at a reasonable price.

We are Stockist of Duplex Steel Buttweld Fittings in More than 20 Countries, Check Dimensions and Price list of SAF 2205 Concentric Reducer

Duplex fittings are generally designed in S2205 and S31803 specifications. The Duplex 2205 Fittings showcase a higher content of nitrogen compared to the latter which gives it higher safety with an existing solid surface. This gives the ASTM A815 UNS S32205 a slight edge over the S31803 grade. The workhorse grade is the most widely used across the family of duplex stainless steel. Duplex 2205 Pipe Fittings possess a tensile strength of 621mpa with a minimum yield strength of 448mpa. These fittings can be elongated by 25% and have a hardness of 293 Brinell HB max. The ASTM A815 UNS S31803 is a magnetic grade and works well in temperatures between -50 degrees C to 300 degrees C. This ASTM A815 S31803 grade can be solution treated in temperatures between 1020 to 1100 degrees C. The process helps harden the grade efficiently.
