Meta Description:
Need stainless steel tubes for sanitary use in food or pharmaceutical facilities across South America? Discover the best grades, surface finishes, and certifications for compliant, clean systems.
Introduction
In South America, the food & beverage and pharmaceutical industries are growing rapidly in countries like Chile, Peru, Colombia, and Argentina. Whether it’s a dairy processing plant, a brewery, or a pharmaceutical filling line, these industries require stainless steel piping systems that offer hygiene, corrosion resistance, and regulatory compliance.
DLSS supports clients in South America with sanitary-grade stainless steel seamless tubes that meet ASTM, DIN, and ISO standards—delivering precision, cleanability, and safety.
1. Key Industry Requirements for Sanitary Tubing
- Smooth inner surface finish (Ra ≤ 0.8μm)
- No dead ends or contamination risk
- Full traceability of material heat number
- Weldability without carbide precipitation
- Resistance to cleaning chemicals and sterilization (CIP/SIP)
Learn more from the 3-A Sanitary Standards and FDA CFR 21 regulations.
2. Preferred Grades & Surface Finishes
| Grade | Typical Application | Notes |
|---|---|---|
| TP316L (EN 1.4404) | Dairy, beer, cosmetics | Excellent corrosion resistance |
| TP304L (EN 1.4307) | Juice, food process water | Economical, easy to weld |
| TP316Ti | High-temperature cleaning systems | Prevents intergranular corrosion |
| 904L / AL-6XN | Ultra-pure water or aggressive CIP | Superior pitting & crevice resistance |
Finish Options:
- Bright Annealed (BA): Ra ≤ 0.8 μm
- Electropolished (EP): Ra ≤ 0.4 μm
- Pickled & Passivated: Standard for external surface
3. DLSS Certifications and Standards
We supply tubes according to:
- ASTM A270 / A269 / A632
- EN 10357 (formerly DIN 11850)
- ISO 2037
- 3-A certified surface treatment (if required)
- EN 10204 3.1 / 3.2 Mill Test Certificates
- ASME BPE standard available upon request
4. Applications in South America
| Country | Sector | Use Case Example |
|---|---|---|
| Chile | Wineries & breweries | CIP loops, fermenter jackets |
| Colombia | Pharmaceutical plants | Water for injection (WFI), clean steam |
| Argentina | Dairy & food factories | Pasteurizer tubes, filling lines |
| Peru | Cosmetic manufacturing | Cream & lotion piping, tank interconnects |
DLSS has provided tubing for sanitary projects across these regions with custom lengths, orbital weld ends, and protective ID sealing.
5. Sanitary Packaging and Delivery
Sanitary tubes must remain free from contamination. DLSS provides:
- Capped ends with nitrogen purge (for BA/EP finish)
- Double PE bagging or paper wrapping
- Packed in plywood boxes or clean racks
- Heat number and Ra value etched on tube surface (optional)
All shipments are export-compliant, with bilingual documents (English + Spanish or Portuguese) for customs.
Frequently Asked Questions (FAQ)
Q1: What’s the difference between A270 and A269 tubes?
A270 is specifically for sanitary use with stricter surface finish and inspection requirements. A269 is more general-purpose.
Q2: Do DLSS tubes meet 3-A or BPE standards?
We offer EP tubes that conform to 3-A 33-03 standards and ASME BPE SF1/SF4, with Ra certification available.
Q3: Can DLSS tubes be autoclaved or steam-sterilized?
Yes. TP316L and EP-finished tubes are compatible with both SIP and WFI systems.
Q4: What is the typical Ra value of DLSS tubes?
Bright Annealed (BA): ~0.6–0.8 μm; Electropolished (EP): ~0.3–0.4 μm. Certification can be included upon request.
Conclusion
Whether you’re building a new pharmaceutical plant in Bogotá or upgrading a brewery in Santiago, selecting the right hygienic stainless steel tube ensures safety, compliance, and long-term reliability.
DLSS is your trusted partner in precision sanitary tubing for South American markets.
