ASME SA312 TP310S Stainless Steel Petrochemical Piping
ASME SA312 TP310S is a high-quality stainless steel pipe used in the petrochemical industry, possessing excellent high-temperature resistance (up to 1150°C or 2100°F) and corrosion resistance. It is renowned for its high strength, suitable for high-pressure and high-temperature environments, and its low carbon content makes it suitable for a variety of industrial applications. "TP" indicates the pipe type, and "310S" indicates that the material composition is low-carbon austenitic stainless steel.


What is the maximum operating temperature of 310 stainless steel?
The temperature limits of 310 stainless steel depend on the application: according to data from AZoM and Dongshang Stainless Steel Co., Ltd., the maximum temperature is 1050°C (1922°F) for continuous use in air and 1150°C (2102°F) for intermittent use. However, the maximum recommended operating temperature for its non-pressure-bearing components is 816°C (1500°F). It is also suitable for cryogenic environments down to -450°F (-268°C).
Standards and Specifications
ASME SA312: Standard for seamless and welded austenitic stainless steel tubes.

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.
