I've dealt with piping systems in marine and offshore setups for years, and one thing always stands out: the wrong fittings can turn a solid project into a nightmare of leaks and downtime. Enter copper nickel alloy butt welded fittings—these guys blend 90% copper with 10% nickel, plus a dash of iron and manganese for extra toughness. They create seamless, welded joints that handle high pressures and corrosive environments without breaking a sweat. At Feiting Pipe, we craft these marine grade copper nickel welded fittings from alloys like C70600 (90/10) and C71500 (70/30), meeting tough standards like ASME B16.9 and EEMUA 234. Folks in shipbuilding, desalination, and oil platforms swear by them for their top-notch seawater resistance and biofouling defense.
