sanitary pipe & tube
TeCarve’s Stainless Steel Sanitary Pipe & Tube products are designed to meet the highest hygiene standards required in food, beverage, pharmaceutical, and biotech industries.
Manufactured from premium-grade stainless steel such as 304 and 316L, these tubes feature ultra-smooth internal surfaces, ensuring minimal residue buildup and easy cleaning. All sanitary pipes are produced under strict quality control, including surface roughness testing, to prevent contamination and support clean-in-place (CIP) systems.
Offered in both welded and seamless types, our sanitary tubes are ideal for systems where cleanliness, corrosion resistance, and pressure integrity are critical.

CUSTOMIZATION
& DELIVERY
Flexible Custom Manufacturing
We customize stainless steel sanitary pipe and tube by diameter, wall thickness, length, seamless or welded construction, and mirror-polished, bright-annealed, or electro-polished surface requirements, including specified internal roughness.
Low MOQ & Rapid Prototyping
Small batch customization and sample production are supported, helping you shorten your development cycle and market entry.
Optimized Lead Time
Most orders ship within 10–25 days after deposit. Exact timing depends on product specification, required documentation, and order volume.
Global Logistics & On-Time Delivery
For sanitary tube exports to over 50 countries, we prioritize PVC wrapping and end caps plus anti-corrosion and moisture protection to maintain clean finished surfaces.
Frequently Asked Questions
What surface finish is required for sanitary stainless steel tube?
Food-grade sanitary service requires Ra ≤ 0.8 µm (32 µin) internal surface roughness; pharmaceutical/biotech service requires Ra ≤ 0.4 µm (16 µin). TeCarve confirms surface finish values on inspection reports supplied with each order.
Which stainless steel grades are used for sanitary tubing?
Grade 316L is the preferred material for sanitary tubing due to its superior resistance to CIP cleaning chemicals, hot water, and chlorides. Grade 304 is used where chemical exposure is minimal. Both are suitable for food-contact use under applicable regulations (e.g., EU Regulation 1935/2004); specific certification requirements should be confirmed per project.
What standards do TeCarve sanitary stainless steel tubes conform to?
Our sanitary tubes meet DIN 11850 (European dairy), 3-A Sanitary Standards (USA), SMS (Scandinavian), ISO 2037, and ASTM A270. Tri-clamp, butt-weld, and plain ends are available in standard and custom sizes.
What industries require sanitary stainless steel pipe?
Sanitary stainless steel pipe is essential in dairy and milk processing, food and beverage manufacturing, pharmaceutical and biotech production, cosmetics, and any hygienic process using CIP (Clean-In-Place) or SIP (Steam-In-Place) systems.
Can TeCarve supply sanitary fittings and clamps to match the tubes?
Yes. Matching tri-clamp fittings, elbows, tees, reducers, end caps, and gaskets in 316L stainless steel are available. Complete hygienic tube systems with matched fittings can be supplied for one-stop hygienic piping procurement.
