Product Description
DLSS supplies ASTM B466 C70600 (O60) seamless pipes in size 42.16 mm OD × 4.0 mm wall thickness × 6000 mm length, manufactured according to ASTM B466 standards. These seamless copper-nickel pipes are tested with 100% Eddy Current Testing (ET) to ensure defect-free quality and safe performance in critical service.
Material C70600 (CuNi 90/10) is a copper-nickel alloy with 90% copper and 10% nickel, plus controlled iron and manganese additions for superior resistance to seawater corrosion, erosion, and biofouling. Condition O60 (annealed) provides excellent ductility and weldability, making these pipes suitable for offshore and marine piping systems.
