Stainless steel straight pipe

Stainless steel straight pipe is a hollow, long, round tube made of austenitic, ferritic, or duplex stainless steel. It features a continuous cross-section and uniform wall thickness. Its manufacturing process typically includes cold drawing, cold rolling, or hot extrusion, and can be welded or seamlessly fabricated depending on the application.

Key features of this pipe include high corrosion resistance, making it suitable for a variety of chemical environments; excellent mechanical strength and toughness, maintaining structural stability under certain pressure and temperature conditions; and surface treatments such as polishing, pickling, or passivation to form a dense oxide layer, further enhancing corrosion resistance. Furthermore, stainless steel straight pipe complies with multiple international standards (such as ASTM, EN, and GB), with clear technical specifications for dimensional tolerances, material composition, and mechanical properties.

Stainless steel straight pipe is widely used in the petrochemical industry, food processing, pharmaceutical equipment, water supply systems, and building structures. Its primary function is to transport fluids and gases or serve as structural support components. Different grades (such as 304 and 316L) and sizes are available to meet specific application requirements.
