ASTM A270 TP304 stainless steel pipe for sanitary applications
ASTM A270 TP304 stainless steel pipe is widely used in sanitary applications due to its high sanitation, corrosion resistance, and smooth surface. Key features include stringent surface finish requirements (low average roughness "Ra"), specialized manufacturing processes such as seamless or TIG welding with specific filler and purge requirements, and a wide selection of sizes and surface finishes to meet the requirements of industries such as food, beverage, and pharmaceuticals.
What is TP304 stainless steel?
ASTM A312 TP 304/304L stainless steel pipe is the most widely used and commonly used stainless steel on the market. These grades of stainless steel are austenitic chromium alloys, also known as "18/8" stainless steel due to their composition of 18% chromium and 8% nickel.

Applications
Food and beverage processing systems, Pharmaceutical manufacturing pipelines, Medical and healthcare processing equipment, Biotechnological plant piping, and Cleanroom and sterile environments.
Additional considerations
Size range:
The standard covers tubes in sizes up to and including 12 inches in outside diameter, but can vary depending on the specific manufacturer's product line.
Customization:
Optional supplementary requirements and custom sizes or lengths can be specified when ordering.
Sterilization:
The smooth, cleanable surface makes it suitable for frequent sterilization processes.
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.
