Welded Pipes are of two types ERW and EFW. A process for producing welded pipe is Electric Resistance Welding (ERW) also known as Contact Welding. Processing of Electric Fusion Welding, also called Continuous Welding begins as coiled steel with appropriate thickness, width and weight is made. 70 30 CuNi Welded Pipes are available in a wide range of sizes and properties. Due to the weld seam, lower operating pressures are stated in accordance with ASME compared to seamless pipes. In general Copper Nickel welded pipe possess tighter dimensional tolerances than seamless pipes and are less costly if produced in same quantities. Copper Nickel Welded Pipe sizes range from 1/8" to 48" inches and the thickness of the pipes are as follows: Sch 5, Sch 5s, Sch 10, Sch 10s, Sch 20, Sch 30, Sch 40s, Sch 40, Sch STD, Sch 60, Sch 80s, Sch 100, Sch 120, Sch XS, Sch XXS, Sch 160. The Copper Nickel pipe is manufactured and finished according to dimension standards such as ANSI B36.10 and ANSI B36.19.

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.
