Duplex pipe fittings

There are industries that often demand for pipe fittings that show excellent properties to resolve their needs and standards.

In such cases, comes a pipe fitting, which offers excellent corrosion resistance and strength characteristics: duplex stainless steel pipe fittings.

They comprise austenite and ferrite at equal proportions. This means that both the ferric and austenitic characteristics are seen. Wide modifications for this grade is seen, and hence this is also the reason why DSS 2205 seamless fittings shows superior corrosion resistance.

Meanwhile, there are industries who blindly choose without checking out their properties and working conditions.

So, when temperature is considered as a factor, excellent ductility is prohibited by alloy 2205 elbow below the operating temperature of -500C.

But when elevated temperature conditions are concerned, the operating temperature should be less that or at 5720F. This is because it shows good strength at this temperature condition; along with excellent resistance to corrosion.

If your industrial standards require duplex steel buttweld fittings for temperature conditions above 5720F, it is strongly advisable that you not choose as it will undergo embrittlement. Furthermore, other degraded properties are also seen.

We are leading Alloy 2205 elbow manufacturer in India

Duplex pipe fittings

Besides this, another feature is seen in the heat treatment of alloy 2205 welded fittings. At 11000C temperature, it is solution treated or annealed; in association with rapid cooling.

Wondering whether your standards are correct or has any flaws? Highly advisable for you to approach us at Mesta INC; where our manufacturers:

  • Focus only on the material standards of the customers and how one can be guided with proper suggestion for SAF 2205 concentric reducer.
  • Cost factor worrying you? Our manufacturers quote only what is necessary at the moment for customers. So, customer pays only for what they aspire.
  • Customers are also assured product confidentiality, where samples of duplex 2205 cap are provided to them. In this way, they can then revert back if they are satisfied with the product.

Our customers have been widely demanding for quality products and due to this, we are one of the most prominent duplex pipe fittings manufacturers in India.

    Things to check during ASTM A815 S31803 fittings Inspection

    Below things are must to inspect before taking delivery of ASTM A815 S31803 fittings

    • Diameter
    • Length
    • Thickness
    • Degree of elbows & bends
    • And Concentricity of reducer
    • Straightness & perpendicularity of the ends of the fitting

    Characteristics of DSS 2205 pipe fittings

    • High resistance to stress corrosion cracking caused by chloride
    • Resistance to corrosion in crevices and chloride pitting
    • A good overall resistance to corrosion
    • Good resistance to corrosion under sulfide stress
    • Excellent workability and weldability
    • High Strength

    Is SAF 2205 Reducer machinable?

    Compared to the austenitic stainless steels from the 300 family, duplex 2205 fittings is a little harder to machine. Higher cutting forces are necessary, and tool wear typically occurs more quickly.
