310S Stainless Steel High Pressure Pipe 12GA 8" Dia, ASME B36.19, Heat-Exchanger Networks
310S Stainless Steel High-Pressure Pipes (12GA Thickness x 8" Diameter) by Jiangsu China Steel Union Industrial Co., Ltd are engineered for extreme heat and corrosion resistance in industrial thermal systems. Compliant with ASME B36.19, these pipes excel in environments up to 1,150°C due to their high chromium (24–26%) and nickel (19–22%) content, which ensures superior oxidation resistance and creep strength. The 8" diameter (219.1mm OD) and 12-gauge (2.66mm) wall thickness balance durability with thermal efficiency, making them ideal for heat exchanger networks, furnace radiant tubes, and refinery pyrolysis units. Seamless construction and pickled surfaces (Ra ≤1.0µm) prevent scaling and carburization in hydrocarbon processing and sulfur-rich flue gas systems.
