Copper Nickel Pipe Fittings

SSEF Industries is a leading manufacturer of copper pipe fittings such as “Curpo Nickel Fittings (Cu-Ni Fittings)” also known as Copper Nickel C70600 (90/10) and C71500 (70/30) fittings in Mumbai, India. SSEF offers a complete range of copper pipe fittings such as Cupro Nickel reducer, Cupro Nickel elbow, Cupro Nickel tee, Cupro Nickel cross, Cupro Nickel stub ends and Cupro Nickel pipe bends.

Copper nickel is known for its strong general resistance to seawater. Due to high alloy concentration Copper nickel fittings are widely used as connectors for piping systems in the ship building and power generation industry. SSEF is a leading exporter and supplier of copper nickel fittings (CUNI fittings) in Saudi Arabia, Qatar, Kuwait and other countries in the GCC region.

We also stocks and supplies a complete range of copper pipes to complement our existing production range of buttweld fittings and flanges. Copper pipes can be supplied in cut to length sizes and also machined or fabricated to meet your piping requirements.
