Industrial Applications of Stainless Steel 304 Large Diameter Pipes
SS 304 large diameter pipes are used in 4 major sectors: oil and gas, chemical processing, water treatment, and food production.
Oil & Gas Pipeline
SS 304 large diameter pipes are used in oil and gas operations for transfer lines and header pipes.
Chemical & Petrochemical Processing
Chemical plants use AISI 304 large bore pipes for reactor feed lines and heat exchanger connections handling mildly corrosive media.
Water & Waste Treatment
Heat exchangers, reactors and process piping in nitric acid and organic acid production rely on 347H for corrosion performance under thermal cycling. Niobium stabilisation prevents weld decay in heat-affected zones.
Food & Beverage Processing
Food and beverage processing lines require sanitary-grade piping.
