Production Process
Product Description
304L/316L SS Round Seamless Pipes excel in precision and durability. 304L, low in carbon, resists intergranular corrosion, ideal for general chemical and food industries. 316L, with molybdenum, boosts chloride resistance, perfect for marine, pharmaceutical, and harsh environments. Seamless construction ensures uniform strength, handling high pressure and temperature reliably. Their round profile enables smooth fluid flow, suiting piping systems. Both grades offer excellent weldability and formability, adapting to complex installations. With long-term rust resistance and hygienic surfaces, they meet strict industry standards, delivering consistent performance in critical applications.
304L and 316L SS round seamless pipes are renowned for their outstanding features. Exceptional Corrosion Resistance: 304L, with its low carbon content (C≤0.03%), offers good general corrosion resistance, especially in mildly corrosive environments like food processing. 316L, containing molybdenum (2 - 3%), excels in resisting chloride - induced corrosion. This makes it ideal for marine applications, chemical processing plants where aggressive chemicals are present, and areas with high salt exposure. Superior Mechanical Properties: Both pipes exhibit high tensile strength, ensuring they can withstand significant internal and external pressures. They also possess excellent ductility, allowing for easy bending, flanging, and other forming operations during installation. This property is crucial for adapting to complex piping system designs. Good Weldability: These seamless pipes can be welded using standard techniques, such as TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding. The low carbon content in 304L and the alloying elements in 316L minimize the risk of carbide precipitation during welding, maintaining the pipes' corrosion resistance in the welded areas. Hygienic and Smooth Surface: Their smooth interior and exterior surfaces prevent the accumulation of dirt, bacteria, and scale. This makes them highly suitable for applications in the food and beverage industry, pharmaceutical manufacturing, and water treatment, where maintaining a clean and uncontaminated flow is essential. High - Temperature Performance: They can maintain their structural integrity and mechanical properties at elevated temperatures. 316L, in particular, shows better high - temperature strength, making it suitable for use in heat exchangers, boilers, and other applications where exposure to high - heat environments is common.
