Super Duplex Steel Buttweld Pipe Fitting Manufacturers, Suppliers

Alpha Overseas is one of the leading manufacturers, suppliers, and exporters of Duplex and Super Duplex Buttweld Fittings, that use high-quality raw materials. We are a top manufacturer, exporter, and supplier of Buttweld Fittings made from Duplex 2205/UNS S31803. The Duplex 2205 Buttweld Fittings have a high yield strength almost double that of conventional austenitic stainless steel. They are a commonly used duplex stainless steel grade material worldwide. Additionally, the UNS S31803 Buttweld Pipe Fittings we provide have remarkable fatigue, stress corrosion, and crack resistance.

It has outstanding corrosion resistance capabilities as a result of its high amount of chromium, molybdenum, and nitrogen. Additionally, they offer remarkably resistance to pitting and crevice corrosion even in oxidizing and acidic conditions. In temperatures around 150 degrees Celsius, the Duplex 2205 Buttweld Pipe Fittings are resistant to chloride stress corrosion cracking. Duplex UNS S31803 Fittings work well in acidic conditions and offer good weldability since ferrite is present in them.

Duplex 2205 is a two-phase, ferritic, austenitic stainless steel that contains 5 to 6% Nickel, 3% Molybdenum, and around 22% Cr. The duplex steel buttweld fittings are available in various shapes, including end pipe caps, stub ends, equal and unequal tees, concentric and eccentric reducers, 45-degree, 90-degree long, and short radius elbows, and many more. They are widely used in oil and gas pipeline equipment, plumbing, chemical, food processing, manufacturing, pulp and paper, water supply systems, power plants, and many other industries.

Furthermore, the super duplex UNS S32750 Buttweld Fittings that we offer have a low carbon content, reducing the possibility of carbide precipitation in the grain boundaries during the heat treatment. They are particularly resistant to uniform corrosion by organic acids like formic and acetic acid because of the high chromium and molybdenum content of UNS S32750 Super Duplex Pipe Fittings. They are also highly resistant to crevice corrosion. Pipe fittings made of super duplex 2507/UNS S32750 have excellent resistance to chloride stress corrosion cracking and strong thermal conductivity with a low coefficient of thermal expansion. Inorganic acids in diluted hydrochloric acid are quite resistant to these pipe fittings.
