316 SS High Pressure Pipe 1500xΦ50mm, ISO 9329, Pitting-Resistant, Desalination Plants
316 Stainless Steel High-Pressure Pipes (1500mm Length x 50mm OD) by Jiangsu China Steel Union Industrial Co., Ltd are engineered for demanding seawater desalination and marine applications. Compliant with ISO 9329, these pipes feature enhanced molybdenum content (2–3%) for superior pitting and crevice corrosion resistance in chloride-rich environments. The Φ50mm (2") diameter and 1500mm length optimize fluid dynamics in high-pressure reverse osmosis (RO) systems, brine discharge lines, and seawater cooling circuits. Seamless manufacturing ensures structural integrity under pressures up to 250 bar, while pickled/passivated surfaces (Ra ≤0.8µm) minimize biofilm formation and scaling. Ideal for coastal and offshore installations, these pipes withstand harsh marine climates and aggressive chemical cleaning cycles.
