ASME SA312 TP310S stainless steel bright annealed seamless pipe
ASME SA312 TP310S stainless steel bright annealed seamless pipe
ASME SA312 TP310S is a bright annealed seamless stainless steel tube with excellent high-temperature and corrosion resistance, suitable for demanding applications such as furnaces and petrochemical plants. Key features include high chromium and nickel content, durability at temperatures up to 1149°C (2100°F), and good toughness at low temperatures. Its seamless construction and bright annealing process provide increased strength, a superior surface finish, enhanced pressure resistance, and the ability to withstand harsh environments.

Construction and Surface Treatment
Seamless: Manufactured using an extrusion process, it has no welds, making it stronger than welded pipe and more suitable for high-pressure applications.
Bright Annealed: The finishing process includes annealing in a controlled atmosphere furnace to clean the surface, providing a smooth, bright finish without the need for pickling or grit blasting.
Applications and Industry Uses
High-Temperature Applications: Commonly used in furnaces, heat exchangers, and other high-temperature environments.
Chemical and Petrochemical: Its corrosion resistance makes it an ideal choice for the chemical, pharmaceutical, and petrochemical industries.
Other Uses: It is also used in food and beverage processing, and some models are used in specialized applications such as urea production.
Gnee Steel specializes in the production of a wide range of stainless steel products. Gnee Steel's product packaging includes: Steel Strapping: Pipes with an outer diameter of 3 inches or less are typically strapped together with polypropylene film to prevent rust during ocean shipping, and then secured with steel strapping. Wooden Cases/Crates: Pipes are typically packaged in wooden cases or crates to protect the pipes during transportation, especially those that are longer or have larger diameters. Seaworthy Export Packaging: Suppliers typically use standard seaworthy export packaging methods, which may include a variety of materials and techniques to protect the pipes during transportation. Tarpaulin Packaging: This prevents rain, seawater, and other external factors from penetrating the export crates during transportation. Gnee Steel specializes in the production and sale of alloy materials. Gnee Steel's products are widely used in the aerospace, chemical, power, automotive, and nuclear energy sectors, and we can provide customized alloy material solutions based on customer needs.
