ASTM B122 Copper Nickel 90/10 Pipe Fittings

Specialist in Manufacturer of Cupro Nickel 90/10 BW 180 degree Elbow, Hot Induction Bend, Piggable Bend, Lap Joint Stub End, Long & Short Stub End.

Copper Nickel 90/10 buttweld fittings, composed of 90% copper and 10% nickel, are renowned for their excellent corrosion resistance, particularly in marine and saltwater environments. 90/10 pipe fittings are meticulously designed and manufactured to comply with several key industry standards, including ASME/ANSI B16.9, ASME B16.28, MSS-SP-43, BS1560, BS4504, and BS10. Available in sizes ranging from 1/2" NB to 48" NB, these fittings come in both seamless and welded types to suit various application needs. They are offered in a wide range of thicknesses, such as Schedule 5S, 10S, 20S, S10, S20, S30, STD, 40S, S40, S60, XS, 80S, S80, S100, S120, S140, S160, and XXS. The forms available include elbows, equal tees, U pipe bends, long and short stub ends, caps, and lap joint stub ends. These fittings are made from high-quality grades like ASTM B122 / ASME SB122 / Copper Nickel 90/10, ensuring superior performance, corrosion resistance, and durability in demanding environments.

Manufacturing Copper Nickel 90/10 pipe fittings involves melting and casting the alloy into billets, which are then hot-rolled and forged into shapes like elbows and tees. Seamless fittings are extruded and drawn, while welded fittings are formed and welded from sheets. The fittings undergo heat treatment to enhance properties and are subjected to rigorous quality control, including dimensional checks and non-destructive testing. After ensuring compliance with standards such as ASME/ANSI B16.9 and MSS-SP-43, the fittings are cleaned, polished, and coated if necessary, before being packaged for distribution.

Cupro Nickel 90/10 pipe fittings offer superior corrosion resistance in marine and saltwater environments, ensuring durability and reducing maintenance costs. Their high resistance to biofouling maintains efficient fluid flow, while excellent strength and durability make them ideal for high-stress applications like shipbuilding, offshore oil and gas, and desalination. These fittings also provide good thermal conductivity, beneficial for heat exchangers, and resist stress corrosion cracking and erosion. Easy to fabricate and weld, they simplify installation and allow customization, maintaining mechanical properties over a wide temperature range for versatile industrial use.
