Nascent Pipe & Tubes is a major selling company and supplier of Copper Nickel 70/30 tubes that are meant to pass some of the strict and excellent industry industrial standards. The tubes containing 70 percent copper and 30 percent nickels and small amounts of iron and manganese are made with improved overall strength and resistance to corrosion, especially in the coastal and salt water areas. Referred to as UNS C71500 tubes and produced under the specifications of ASTM B466 and ASME SB466, the tubes are characterized by long lasting performance in severe service environments.
We recommend our Copper Nickel 70/30 Tubes in the shipbuilding industry, desalination plant, heat exchanges, offshore oil rigs, condensers and power generation plants as they easily resist salt and black corrosion as well as biofouling and the fast flow of seawater. They are very good to work and weld and therefore applicable in fabricated pipework systems, cooling circles, and condensate lines. The natural thermal conductivity and temperature stability of the alloy make it the best choice when it comes to heat transfer in applications involving high pressure and temperature.
