Lean Duplex 2101 Fittings

Manufacturing Process Of Lean Duplex 2101 Fittings


Using a forging machine to lower the outside diameter and bevel the pipe end or extension is one method of making forged fittings.

Rolling Wheel

The core is inserted into the pipe using butt weld fittings. After that, processing the rim and pushing the exterior with a roller.


Expand the pipe end in the punching machine to the desired size and shape by using a tapered core.


for creating bend and elbow fits. There are three typical approaches. There are three or four rollers: one is for stretching, one for stamping, and the third is for rolling.


A rubber is inserted into the tube and compressed with a punch, causing the pipe to bulge; hydraulic bulging forming is an additional technique.

What are Lean Duplex 2101 fittings?

Lean Duplex 2101 fittings are corrosion-resistant fittings made of duplex stainless steel alloy featuring a balanced mixture of austenite and ferrite phases, offering excellent strength, durability, weldability and formability while remaining weldable and formable for welding or formed applications. Lean Duplex 2101 fittings can be found across industries like oil & gas production, chemical processing facilities and marine applications where high corrosion resistance and mechanical strength is desired.

Specifications and Sizes of Lean Duplex 2101 Fittings

Lean Duplex 2101 fittings typically come in various specifications and sizes to meet various industrial applications, with specifications like ASTM A182 for forged fittings and ASTM A815 for seamless and welded. Common standards may also exist regarding their manufacturing. Sizes typically range from 1/2 inches up to 24 inches in diameter, and variations are available based on specific requirements. These fittings are known for their corrosion resistance, strength, and durability - characteristics which make them suitable for use in demanding environments like offshore oil and gas production, chemical processing plants, desalination facilities and desalination plants. Furthermore, many comply with industry standards like ASME B16.11 or B16.9 to guarantee compatibility and reliability within piping systems.
