ASTM A270 TP304 Sanitary External Threaded End Stainless Steel Pipe
ASTM A270 TP304 Sanitary External Threaded End Stainless Steel Pipe
ASTM A270 TP304 Sanitary Stainless Steel Pipe is a type of pipe used in food, dairy and pharmaceutical applications that meets specific standards for hygiene and corrosion resistance. It is made from 304 stainless steel and comes in various finishes, with the "male end" specifying the type of connection it has. The standard focuses on special surface finish and high purity requirements for applications where cleanliness is critical.
What are the specifications of 304 stainless steel pipe?
304 stainless steel pipe specifications are defined by its chemical composition (18% chromium, 8% nickel), its corrosion resistance, and its mechanical properties such as a minimum tensile strength of 515 MPa and a yield strength of 205 MPa. lit are manufactured to standards such as ASTM A312 in sizes ranging from 1/8" to 30" NB and available in a variety of sizes (e.g. Schedule 40, 80) and types (seamless, welded).
ASTM A270 TP304 Sanitary External Threaded End Stainless Steel Pipe
ASTM A270 TP304 stainless steel pipe is the gold standard in the sanitation industry. With its excellent cleanliness, corrosion resistance and formability, it is widely used in high-demand fields such as food and medicine. Suitable for industries with extremely high requirements on cleanliness and corrosion resistance. When selecting, priority should be given to the surface treatment level (such as electrolytic polishing) and connection method to avoid use in strong corrosion or high temperature extreme environments.

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.
