Copper Nickel Flanges

Copper Nickel Flanges have demonstrated excellent resistance to seawater, organic compounds, saline water, salts, diluted non-oxidizing acids, and other chemicals.

Because of their great resistance to marine organisms such as barnacles, Cupro Nickel Flanges are utilised in seawater piping systems. It is useful for connecting pipes, pumps, valves, and other piping system components. Cuni Flanges are mechanical devices used to connect pipes that are often welded or bolted.

Copper Nickel Slip On Flanges are ideal for low-pressure applications since they are simple to install and weld onto various pipes. It is an excellent material for commercial and naval transportation, desalination plants, heat exchangers and equipment, sea water and hydraulic pipelines, fish farming cages, offshore renewables, ship and boat hulls, and other applications in marine and salty settings.

Copper Nickel Lap Joint Flange is a pipe flange that slides directly over the pipe and is most usually used with stub end fittings. It is frequently used for applications that need regular dismantling. It has greater strength and durability, as well as resistance to corrosion and erosion in natural environments such as saltwater, brackish water, and treated water.

A solid flange is Copper Nickel Blind Flange. Its purpose is to close off an unused portion of pipe or nozzle on a vessel. Cuni Blind Flange is more durable and resistant to impingement corrosion.

The Copper Nickel Weld Neck Flange has a long tapered hub that progressively extends over the wall thickness of a pipe or fitting. It serves as a significant reinforcement in a variety of applications that include high pressure, sub-zero, and/or higher temperatures.

The opper Nickel Inner Flange is utilised in a variety of applications to secure diamond blades, grinding wheels, and multi-discs. It is made of high-quality metal for extra durability. It can only be toughened by cold working and is extremely corrosion resistant.

Without welding, the Copper Nickel Threaded Flange can be joined to the pipe. It is a threaded bore that corresponds to an external thread on the pipe. The same as slip-on pipe flanges, which are utilised with pipes with external threads.

Cuni Composite Flange has committed to copper nickel inner and carbon steel exterior flanges. It has excellent anti-corrosion properties.
