Copper nickel pipe manufacturer in india

Copper nickel pipe

What is a copper nickel pipe?

These pipes usually contain copper (70-90%), nickel (10-30%), and other elements for strength, including iron and manganese. A copper nickel pipes is available in several sizes, such as 0.2 to 120mm.

As trusted copper nickel pipe suppliers, Manifest Alloys partners with esteemed industrial clients from different spheres.

Cunifer welded pipe and cuni seamless pipe manufacturer in India

What is the application of a copper-nickel pipes?

From seawater cooling to firewater systems, hydraulic tubing, and heat exchangers, a copper nickel brake pipes has widespread industrial applications. It also provides consistent performance in seawater pumps, condensers, and offshore refineries.

A cunifer pipes can protect your application from barnacles and other marine life due to its natural resistance to bio-fouling.

How to weld a cunifer pipes?

The standard technique for welding a cupro nickel pipes is TIG, or tungsten inert gas, also known as GTAW (gas-shielded tungsten-arc welding).

The process uses a tungsten electrode (non-consumable) to make a durable weld. The surface must be contaminant-free. Besides this, a cuni pipes does not require pre-heating or post-welding treatments.
