Cupro Nickel 70 Hydraulic Fittings Manufacturer

Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality Cupro Nickel 70 Hydraulic Fittings, which are commonly specified in heat exchanger or condenser tubes in a wide variety of marine applications. Welding Cu-Ni 70 / 30 Hydraulic Fittings can be welded using gas shielded arc welding, spot welding, coated metal arc welding, butt welding, seam welding, brazing, soldering, and oxyacetylene welding processes. Deoxidized Cupro Nickel 70 / 30 Hydraulic Type Fittings (usually deoxidized with phosphorus) is a material that can be readily brazed or welded without fear of embrittlement. Copper Nickel 70 / 30 Hydraulic Type Fittings are durable, corrosion resistant and available in different grades, thicknesses and dimensions.

Cupro Nickel 70 Hydraulic Fittings

Three sets of strain – cycled fatigue tests have been conducted at three laboratories on wrought Cu-Ni 70 / 30 Hydraulic Type Fittings. The main wrought Cupro Nickel 70 / 30 Forged Hydraulic Fittings chosen for seawater service contain 30 % Nickel. A laboratory investigation was carried out on the effect of sulfate – reducing bacteria (SRB) and inorganic sulfide on the corrosion behavior of Copper Nickel 70 / 30 Forged Hydraulic Fittings in seawater.

These Cu-Ni 70 / 30 Forged Hydraulic Fittings for Marine application are very important for all Industrial fields. We supply UNS C71500 Hydraulic Fittings for industries all throughout the India and the world. UNS C71500 Hydraulic Type Fittings is used for a variety of industries; including marine environments, power generation, offshore, oil & gas and Defence sectors.
