Super Duplex Ferrule Fittings

Super duplex ferrule fittings specifications

What are Super Duplex Ferrule Fittings?

Applications warranting above-par strength and corrosion resistance benefit from these hardy products. Super duplex ferrule fittings comprise austenite and ferrite grades (50-50) and adapt well to marine and chemical processing sectors. Quick to install and leak-tight under severe environmental conditions, these products can assume designs like tees, couplings, and adapters.

UNS S32750 tube fittings contain 25% chromium and 7% nickel. Customers can also use Grade 2760, which has more copper and tungsten to resist hydrochloric and sulphuric acids.

What are the pressure and temperature ratings for Super Duplex Ferrule Fittings? How are they affected by the fitting's dimensions and alloy composition?

The typical operating temperatures for super duplex tube fittings can reach 150°C. They can withstand pressures from 150 to 2500 lbs. These traits make them sound selections for industries like flue gas desulphurization, centrifuges, and heat exchangers.

The alloy composition has a bearing on its environmental capacities, wherein the chromium content in an SDSS DIN 1.4410 instrumentation fitting improves the resistance to oxidation at high temperatures.

Customers can specify dimensions per their requirements, noting that thicker dimensions will mean more time for heat transfer. A SAF 2507 compression fitting gets produced in sizes ½" to 24".

What is ultrasonic testing and radiography? How is it used to ensure the quality and reliability of Super Duplex Ferrule Fittings?

Non-destructive approaches effectively detect cracks and defects in ASME SA 182 SDSS ferrule fittings. They are indispensable in quality control management to certify fitness for sensitive applications.

Radiography uses X-rays or gamma rays to diagnose defects in super duplex single ferrule fittings. Issuing 100% radiography certificates is a standard industrial practice across vendors.

Ultrasonic testing is more accurate even for thicker sections and does not impact human health. Moreover, a zeron 100 UNS S32760 instrumentation fitting may have volumetric cracks that UT can diagnose using sound waves. It needs to access only one side.

The test results of a super duplex steel 2507 tube fitting should be a part of the MTC, with other requisite documents like raw material certificates and third-party inspection reports.
