ASTM A270 TP304 austenitic stainless steel seamless sanitary grade food industry tubing
ASTM A270 TP304 austenitic stainless steel seamless sanitary grade food industry tubing
ASTM A270 TP304 seamless sanitary stainless steel tubing is a high-quality stainless steel product designed specifically for the food industry due to its high cleanliness, corrosion resistance, and smooth surface finish. Key characteristics include the TP304 austenitic stainless steel material, which provides excellent machinability and durability, as well as tight dimensional and surface finish tolerances to ensure hygienic performance. This tubing undergoes rigorous quality control, including mechanical property, chemical composition, and surface finish testing, to meet the demanding requirements of industries such as food and beverage processing, pharmaceutical systems, and water treatment.
What is the ASTM standard for 304 stainless steel pipe?
ASTM A312 TP304 pipe is used in high pressure and high temperature applications due to its high operating temperature and strength of 870 degrees Celsius. SS UNS S30400 ERW pipe has a minimum yield strength of 205MPa and a minimum tensile strength of 515MPa.

Global project experience
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.
