The two ferrules in Copper Nickel tube fittings separate sealing and tube gripping functions; each ferrule is optimised for its function. The front ferrule creates a seal against the fitting body and on the tubing outside diameter. As the nut is turned, the back ferrule axially advances the front ferrule and radially applies an effective tube grip. Dimensions of ferrule fittings range from 6mm to 38mm in OD and 1/4" to 1 1/2" in inches. Tube Fittings are used in a wide range of Industries including Petrochemicals, Energy, Food, Biotechnology, CNG, Pharmaceutical, Pulp and Paper, Mining, Marine, Packing and Printing Industries etc. Following are different types of tube fittings as per design, installation and maintenance -

Copper Nickel Compression Fittings — Compression Tube Fittings are the first tube fittings to come into existence. Its three components nut, body and gasket ring or ferrule use a friction grip on the tube. Thus, no special tool is required in assembling such types of fittings. Some major types of Tube Fittings are Tube to Union Fittings, Tube to Male Fittings, Tube to Female Fittings, Tube to Pipe Fittings and Tube Fittings Accessories. Its seals are often line-type, providing one of the most effective metal-to-metal seals.

Copper Nickel Flare Fittings / Ferrule Fittings — Flare Fitting is made up of a nut, sleeve and body with a flare or coned end. Often, the sleeve is used as a self-flaring option, usually on the thinner wall or softer tubing materials. Flare FittingS can handle high pressures because of its larger seal area and is available in a variety of alloy and stainless steel grades. However, special flaring tools are required to prepare the tubing for installation. Flare Fittings are often referred as Ferrule Fittings.

Properties of 70 30 CuNi alloy

70 30 Copper-Nickel Cold Forming and Hot Forming

With good hot and cold working properties, copper nickel alloy responds well to most fabrication processes. Due to properties inherited from Copper, Copper-Nickel alloy is can be easily drawn and spin.

70 30 Copper-Nickel Machining

Copper-nickels can be cut using most conventional cutting processes. Plasma-arc cutting is fast, accurate and economical. Laser and abrasive water jet cutting are also possible The machinability rating of 70 30 copper-nickel alloy is 20%.

70 30 CuNi Welding

Copper Nickel Alloys can be easily joined by soldering, brazing and a variety of welding methods such as gas shielded arc welding, spot welding, coated metal arc welding, butt welding, seam welding, brazing, soldering and oxyacetylene welding processes.

70 30 CuNi Corrosion Resistance

Copper-nickel Alloys have good resistance to chloride pitting and crevice corrosion. They have excellent corrosion resistance against moisture, non-oxidising acids, alkalis and salt solutions, organic acids and to gases such as oxygen, chlorine, hydrogen chloride, hydrogen fluoride, sulphur dioxide and carbon dioxide. It is found that the corrosion rates of CuNi alloys are 0.02-0.002mm/year in sea-water.
