Super Duplex Steel Tube Fittings Manufacturer, Supplier & Stockist
Kalpaturu Piping Solutions are the suppliers of high-quality 2507 Super Duplex Double Ferrule Fittings that are famous in terms of high corrosion and pitting resistance. Such fittings are made of a higher content of chromium, thus making them more suitable in the high-demand industries than normal duplex materials. They have great tensile strength and hence are reliable, and that is why the Super Duplex F53 Bulkhead Union is being widely used in onshore and offshore operations.
We also have UNS S32750 Ferrule Fittings that are used in the oil, gas and petrochemical industries, commonly due to their exceptional acid resistance. The Super Duplex 1.4501 Compression Couplings are long-lasting in harsh chemical conditions, and the UNS S32760 Compression Nuts are normally used in such critical applications as heat exchangers, marine construction, shipbuilding, and the pulp and paper industries.
Kalpaturu Piping Solutions also distributes 1.4507 Super Duplex Flare Fittings that are used in the connection of metal tubing. The fittings, which are used to fit DIN 1.4507 instrumentation tubing, are deemed to be safe and efficient due to the decreasing chances of leakages of hazardous fluids that make them a critical component of an instrumentation system.
Kalpaturu Piping Solutions is committed to quality, durability and precision, hence offering fittings which are of global standard and give reliable service in industry, marine as well as chemical use.

What is Super Duplex Tube Fittings?
The Super Duplex Tube Fittings consist of the super duplex alloy; this alloy is composed of ferritic and austenitic. The chemical constituents of the material are iron, chromium and nickel, with molybdenum added to it. The combination of features in the Super Duplex Compression Fittings is very distinct, and it is an excellent option when it comes to dealing with the instances of localised corrosion. The Super Duplex Instrumentation Fittings are highly resistant to pitting and stress corrosion cracking at moderate temperatures in comparison to any standard grade of stainless steel. The Alloy 2507 Compression Tube Fittings are also very popular in the different industries due to their high tensile strength.
