Duplex Ferrule Fittings

Duplex ferrule fittings

What are duplex ferrule fittings?

These products possess a distinctive 50-50 microstructure of austenite and ferrite grades. Duplex ferrule fittings show strength, corrosion resistance, and low maintenance. Multiple industries use these products for consistent long-term performance, for instance, pulp and paper plants and flue-gas cleaning.

We are duplex ferrule fittings manufacturer, composed of 22% chromium, 5% nickel, and 3% molybdenum and nitrogen, can endure temperatures up to 572°F or 300°C. They can withstand sulfuric, acetic, and phosphoric acids and salts without facing deformation.

DIN 1.4462 double ferrule fittings are easy to assemble and integrate with the application. They get produced as unions, tees, reducers, connectors, etc., in sizes specified in international specifications like ASTM and DIN.

How are Duplex Ferrule Fittings manufactured?

The usual technique for producing duplex instrumentation fittings is hot forming, which involves heating the material above the recrystallisation temperature. The assembly uses a body, a tightening nut, and a ferrule to build a tight seal when compressed.

We are duplex ferrule fittings supplier in India, we can also get manufactured by cold forming. These products have better quality and higher strength.

The chosen technique depends on the level of precision required, application needs, and your budget. It is vital to monitor each production stage to guarantee tight tolerance and compliance. Generally, the Mill Test Reports have heat lot numbers so the buyers can trace UNS S32205 ferrule fittings.

We are one of the leading suppliers of SS ferrule fittings that are sourced utilizing high grade raw materials. We dispatch Duplex ferrule fittings to Australia, New Zealand, and Solomon in 7 to 10 days.

How is PMI testing used to ensure the integrity and composition of Duplex Ferrule Fittings?

PMI, or Positive Material Identification, is an effective technique to verify the integrity of duplex ferrule tube fittings. It involves handheld X-ray fluorescence and can even check for the correct filler material in welding.

The composition of these products also gets examined through chemical spectrometry. Other NDT processes for a UNS S32205 compression fitting, like radiography and ultrasonic assessment, can detect microstructural problems.

Advanced quality control must also cover compliance with the desired standards, for example, ASME SA276 UNS S31803 ferrule fittings. It avoids risking liabilities arising from non-compliance with global standards, government requirements, and safety norms.
