90/ 10 Copper Nickel Flanges manufacturer in India

90/ 10 Copper Nickel Flanges

C70600 Blind Flange and 70/30 Cuni Flanges supplier in Mumbai

Copper Nickel Flanges has proven to be very resistant to seawater, organic compounds, brine water, salts, diluted non-oxidizing acids, and more

Cupro Nickel Flanges are used in seawater piping systems due to a high resistance towards marine organisms such as barnacles. It is useful for connecting pipes, pumps valves, and other equipment to form a piping system. Cuni Flanges are usually welded or screwed it is mechanical device to connect pipes.

Copper Nickel Slip On Flanges are suitable for low-pressure applications and are easy to install and weld onto different pipes. It is an ideal material for use in marine and saltwater environments for commercial and naval shipping, desalination plants, heat exchangers and equipment, sea water and hydraulic pipelines, fish farming cages, offshore renewables, ship and boat hulls and more.

Copper Nickel Lap Joint Flange is slide directly over the pipe and is most commonly used with stub end fittings and it is often used for applications that require frequent dismantling. It has improved strength and durability, and also it is resistance to corrosion and erosion in natural waters, including seawater, brackish and treated water.

Copper Nickel Blind Flange is a solid flange. The purpose of it is to block off a section of pipe or a nozzle on a vessel that is not used. Cuni Blind Flange is stronger and has superior resistance to impingement corrosion.

Copper Nickel Weld Neck Flange has a long tapered hub that goes gradually over to the wall thickness from a pipe or fitting. It provides an important reinforcement for use in several applications involving high pressure, sub-zero and / or elevated temperatures. 

Copper Nickel Inner Flange is used to secure diamond blades, grinding wheels, and multi-discs for a variety of applications. It is manufactured of high quality metal for added durability. It can hardened only by cold working and is highly resistant to corrosion

Copper Nickel Threaded Flange can be attached to the pipe without welding. It is a threaded in the bore which matches an external thread on the pipe. Same like slip-on pipe flanges that are used with pipes that have external threads.

Cuni Composite Flange committed with copper nickel inner flange  and carbon steel outer flanges It has good ability of anti-corrosion
