Duplex compression tube fittings

Duplex tube fittings

A fitting that exhibit accurate and precise geometry for covering wide range of industrial applications is duplex tube fittings.

Adding to this, they comprise higher contents of chromium, nickel and molybdenum. This means that they are widely demanded by applications where corrosion resistance is needed. They even show good strength characteristics and are highly durable.

Still worried on where to get quality assured and top notch DSS pneumatic fittings, no need to worry as pipingmaterial.ae provides customers with services; where:

Here, customers are not charged highly from suppliers. Thanks to the supplier’s genuineness, where they are 100% trusted and verified. So, customers pay only for what is demanded.

For customers who need small amounts, but at retail pricing? Suppliers quote reasonable pricing for the demands which customers aspire. So high-cost factor is eradicated; but this depends completely on customers.

Prior delivery services? Highly advised to check out the contact details of suppliers.

There are many other features for both the suppliers and customers that make it one of the prominent and leading duplex tube fittings suppliers in UAE. Because they comprise higher content of nickel, molybdenum and chromium, duplex stainless steel ferrule fittings offer outstanding corrosion resistance properties. Not only this, industries demand for ferrule fittings in environments where there is Sulphur and chlorine, where they offer resistance to stress corrosion cracking.

DSS high pressure compression fittings are known to show good strength characteristics, along with being highly durable. They also last for longer periods, thanks to their chemical composition and temperature withstanding properties. Other than this, the suitable pressure conditions required is between the range of 75-400 psi. Adding to this, they are also recommended for use case in extreme temperature conditions, be it low or high. The temperature range required is -65-200°F.

For identifying both BSP and NPT threads, simply check out the flank angles.

In the case of NPT threads, the flank angle is 60°, whereas it is 55° in the case of BSP for duplex stainless steel flare fittings.

Wide range of industrial applications are seen in the case of duplex steel instrumentation fittings. Below are some of them:

  • Petrochemical industries, due to high pressure and temperature tolerance.
  • Often seen in defence applications.
  • Shipbuilding also needs instrumentation fittings because of excellent corrosion resistance to acids and general corrosion too.
  • Used for power generation processes.
