Duplex steel fittings are a type of stainless steel alloy known for their exceptional strength and corrosion resistance. They are composed of a mixture of austenitic and ferritic stainless steels, offering a unique combination of properties.
Duplex steel fittings boast high strength, making them suitable for applications requiring durability. Furthermore, their excellent corrosion-resistance makes them suitable for marine or chemical processing environments.
Duplex steel fittings stand out among their rivals due to their excellent machinability, meaning that they can easily be formed, shaped, drilled, and formed into various components for efficient production processes.
Duplex steel fittings feature superior corrosion resistance when compared to many other forms of stainless steel, making them the go-to choice in environments prone to exposure to potentially corrosive elements, providing extended longevity and reliability in service life.

Duplex steel fittings boast excellent weldability. Common techniques used to weld these parts include gas tungsten arc welding (GTAW) and shielded metal arc welding (SMAW), providing plenty of fabrication flexibility.
Duplex steel fittings find use across industries including oil and gas, chemical processing, desalination plants and offshore platforms. Their strength, corrosion resistance and weldability makes them suitable for high pressure environments such as these.
Duplex steel fittings have found widespread application across a variety of sectors and applications - pipelines, pressure vessels, heat exchangers and structural components in industrial plants are just a few areas where duplex fittings find use. Bridge construction sites as well as power generation and transportation infrastructure projects also rely heavily on duplex steel's durability and dependability - characteristics highly valued among its users.

Forging
Making method of forged fittings,using forging machine bevels the pipe end or extension, reduce the outside diameter.
Rolling Wheel
Butt weld fittings, putting the core in the pipe. Then pushing the external by roller and processing the rim.
Stamping
Using tapered core to expand the pipe end to the required size and shape in the punching machine.
Bending
For making elbow and bend fittings. There are three commonly methods. One is stretching , another is stamping , the third is roller , there are 3-4 rollers.
Bulging
A rubber is placed in the tube and the top with a punch compression, then the pipe is bulged forming; Another method is hydraulic bulging forming.
