317L stainless steel pipe is a corrosion-resistant steel pipe with high chromium, nickel and molybdenum content. It is often used in occasions that require high temperature resistance, corrosion resistance and high strength, such as chemical and petrochemical industries, power generation and sewage treatment. Stainless steel 317L pipe is available in various forms, it can be SS 317L seamless pipe or 317L stainless steel welded pipe, SS 317L square pipe and 317L stainless steel round pipe, thin wall or thick wall. You can also choose from various lengths to meet your specific requirements. Whether you need short pipe for low pressure applications or long pipe for high pressure applications, you can find what you need stainless steel 317L stainless steel SUS 317L pipe.

317L stainless steel pipe material is a low carbon austenitic stainless steel containing molybdenum. ASTM A312 TP317L pipe has more chromium, nickel and molybdenum added for better corrosion resistance and enhanced chemical resistance to sulfurous acid, acetic acid, formic acid, citric acid and tartaric acid. Due to the low carbon content of ASME SA312 UNS S31703 pipes, it has high resistance to intergranular corrosion. SS 317L ERW pipe is also resistant to sensitization when welded and has higher creep, fracture stress and tensile strength at elevated temperatures. 317L stainless steel pipe has excellent oxidation resistance and exhibits low fouling rates in ordinary atmospheres at temperatures up to 1600-1650°F (871-899°C). SS 317L SCH 40 pipe is non-magnetic in the annealed condition but may become slightly magnetic after welding.

317L Stainless Steel Pipes Vs 304L / 316L Stainless Steel Pipes
DIN 1.4438 stainless steel pipes alloy is similar in composition to 316L and 304L and is an austenitic molybdenum, chromium, nickel stainless steel alloy. Due to its higher molybdenum content, 317L provides increased resistance to pitting and stress corrosion cracking, especially in chloride or halide-rich environments. 317l stainless steel pipe has higher creep strength, breaking stress and tensile strength than its 316L and 304L counterparts, making it an excellent solution for demanding applications in offshore, pulp and paper mills, and chemical processing plants.

 

Application of ASME SA312 UNS S31703 Pipes

• Chemical reactors, heat exchangers, pipes and devices in the chemical industry.
•  Platform equipment, generator sets and refinery facilities in the oil and gas industry.
• Dyeing machines and textile equipment in the textile industry.
• Deinking devices and paper machines in the paper industry.
• Treatment equipment and pipelines in the sewage treatment industry.
• It is often used in the design of large-scale buildings, public buildings and urban furniture.
