A 270 / BPE
Standard Specification for Seamless and Welded Austenitic Stainless Steel Sanitary Tubing

Overview

1.1 This specification covers grades of seamless and welded austenitic stainless steel sanitary tubing intended for use in the dairy and food industry and having special surface finishes. Pharmaceutical quality and finishes may be requested, as a supplementary requirement.

1.2 This specification covers tubes in sizes up to and including 4 in. (101.6 mm) in outside diameter.

1.3 The values stated in inch-pound units are to be regarded as the standard.

1.4 Optional supplementary requirements are provided, and when one or more of these are desired, each shall be so stated in the order.

Key Features:

• Corrosion Resistance: Excellent resistance to a wide range of corrosive environments, including acids, alkalis, and chloride-containing environments.
• Sanitary Properties: Smooth interior surfaces to minimize the risk of contamination and facilitate easy cleaning and sterilization.
• Dual Grades: TP304 and TP304L represent two grades of stainless steel, with TP304L having a lower carbon content to enhance weldability and reduce the risk of carbide precipitation.
• Mechanical Properties: Good strength and ductility, making it suitable for forming and fabrication.
• Welded Construction: Manufactured using a welding process, which is then polished to achieve a smooth and clean surface finish.

Benefits:

• Hygienic and Sanitary: Smooth interior surfaces prevent the buildup of contaminants and facilitate easy cleaning and sterilization.

• Corrosion Resistant: Excellent resistance to a wide range of corrosive environments, ensuring long service life.

• Good Weldability: TP304L’s lower carbon content minimizes the risk of carbide precipitation during welding, enhancing weld quality.

• Versatility: Suitable for a wide range of applications in various industries due to its excellent mechanical and corrosion-resistant properties.

• Compliance with Standards: Manufactured to meet the stringent requirements of ASTM A270, ensuring high quality and reliability.

Applications:

• Food and Beverage Industry:Used in the processing, handling, and transportation of food and beverages due to their sanitary properties and resistance to corrosion.
• Dairy Industry:Ideal for milk processing, cheese production, and other dairy applications where cleanliness and hygiene are paramount.
• Pharmaceutical Industry:Used in the manufacturing of pharmaceuticals, including the production of drugs and medical devices, where contamination control is critical.
• Biotechnology:Suitable for bioprocessing applications, including the production of biologics and other biopharmaceutical products.
• Brewing Industry:Employed in breweries for the production and transportation of beer and other alcoholic beverages, ensuring sanitary conditions.
• Cosmetic Industry:Used in the production and processing of cosmetics and personal care products, where purity and cleanliness are essential.
