Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Cupro Nickel 90 Tube to Female Pipes, which is relatively insensitive to stress corrosion. Because of this, Cu-Ni 90 / 10 Tube Fittings is used for marine hardware, piping systems and sometimes for the propellers, crankshafts and hulls of premium tugboats, fishing boats and other working boats. Small amounts of iron and manganese in these Cupro Nickel 90 / 10 Compression Fittings are added to improve corrosion resistance in high – velocity waters, including seawater. Copper Nickel 90 / 10 Female Connector Fittings is often used in condensers, condenser plates, distiller tubes, evaporator and heat exchanger tubes, salt water piping, and ferrules.
In spite of the appropriate properties of these Cu-Ni 90 / 10 Ferrule Fittings, instances of failure have been experienced in practice. Benefit of Cupro Nickel 90 / 10 Double Ferrule Fittings is its high resistance to befouling: in recent years this has led to sheathing developments particularly for structures and boat hulls.
These Copper Nickel 90 / 10 Compression Tube Fittings are a copper-nickel alloy with low resistivity suitable for use at temperatures up to 300 Degree C (570 Degree F). Cu-Ni 90 / 10 Female Connector Tube Fittings prevents stress corrosion cracking and pitting and crevice corrosion. These Cu-Ni 90 / 10 Compression Fittings is resistant to acid solutions and highly resistant to stress corrosion cracking, and impingement corrosion.
