Duplex Pipe Fittings

Duplex Pipe Fittings

What are duplex pipe fittings?

If you need to deal with scenarios, where probability of corrosion or rust is high, then it is highly recommended for you to choose duplex stainless steel fittings. This is one of the reasons why they are employed by many industrial demands and standards. This is mainly because they are composed of 50:50 equal ratio of austenite and ferrite contents. It also means that they comprise both austenitic and ferritic properties. On the other hand, duplex stainless steel pipe fittings not only resist general corrosion, but you would also see them resisting stress corrosion cracking.

There are industries that demand for duplex weld fittings to resist seawater corrosions. This is mainly restricted for marine or other pipeline applications, as for them, corrosion resistance and durability is important. So, to deal with this, duplex buttweld fittings is highly recommended. It resists seawater corrosion and help last for longer period of time. Adding to this, joining and welding are one of the superior and pivotal steps that are employed for manufacturing such fittings. The manufacturing is done as per the standards: ASTM A815.

This standard, cover for the seamless and welded construction of the ferritic and austenitic 2205 elbow, tee, reducer, street elbow, end caps and buttweld cross. So, the mode of manufacturing goes hand in hand with compliance with the material standards. This is very important as the product then becomes genuine and that customers or industries who are interested can then choose duplex 2205 pipe fittings. Adding to this, material standard ASME B16.9, also covers for how it shows excellent properties when welded permanently.

Purchase duplex steel pipe fittings and alloy 2205 reducer as per ASTM A815 at reasonable price from genuine suppliers in middle east

Advantages –

  • The fittings have good mechanical strength and corrosion resistance. They offer a combination of properties from austenitic and ferritic steels at an affordable rate.

Disadvantages –

  • They cannot be used above 600° F, because the material loses its strength and becomes brittle.

Compared to the 300 series, Alloy 2205 Buttweld Elbow is resistant to chloride stress corrosion cracking and localized corrosion (like pitting and crevice corrosion).

Because the alloy has good corrosion resistance properties, Duplex Pipe Fittings are preferred in applications like Chemical process vessels, Food processing equipment, heat exchangers, Flue gas desulfurization equipment, Pulp mill digesters, Oil field piping and heat exchangers.

Fittings are made either seamless or welded. The production of welded fittings involves using metal sheets, cut into the shape of a fitting with the help of a template. After cutting the sheet, the metal is joined together with a weld seam on one side. Seamless fittings tend to have higher strength because they have no seam. Like pipes, some of these fittings may be pushed, bent and expanded simultaneously with the help of a mandrel process.
