Sanitary ASTM A270 Tubing for Food, Beverage and Dairy Process Lines (40″ Precut)

Bright Annealed Polished Sanitary Tubing ASTM A270
Available in 316L Stainless Steel
Stamped with Heat Lot Number
Manufactured in accordance with 3A Standards for sanitary line process requirements

Engineered for Hygienic Excellence in Critical Industries

Our ASTM A270 stainless steel sanitary tubing is precision-crafted for industries where cleanliness and reliability are paramount. Made from seamless 316/316L stainless steel with a mirror electropolished finish (Ra ≤15 µin), this tubing meets rigorous standards for:

Food & Beverage: Dairy processing, brewery transfer lines, juice production.
Pharmaceutical: Sterile API manufacturing, vaccine production.
Biotech: Fermentation systems, cell culture media transfer.
Compliance: ASTM A270, 3-A Sanitary Standard

Solve These Industry Challenges

“Bacterial Buildup in Rough Surfaces”

→ Electropolished Finish: Smooth interior (Ra ≤15 µin) prevents biofilm formation, ensuring CIP/SIP efficiency.

“Corrosion in Acidic Environments”

→ 316L Grade: Resists nitric acid, caustic cleaners, and chloride solutions.

“Compliance Failures During Audits”

→ Full Documentation: Mill test reports (EN 10204 3.1) and 3-A certificates included.

“Long Lead Times for Custom Sizes”

→ Rapid Turnaround: Standard sizes ship in 24hrs; custom cuts (1/2" to 6") in 5 days.

The pressures shown in the table above are calculated using Barlow's Formula and the following properties:
• material: 304
• yield strength (PSI): 30,000
• tensile strength (PSI): 75,000
Working Pressure = ¼ of Burst Pressure, these calculate from -20°F to 100°F.
