Hygienic, Corrosion-Resistant & FDA-Compliant Solutions
Our sanitary stainless steel piping systems are engineered for industries where purity and safety are non-negotiable. Made from 316L/304 stainless steel with electropolished surfaces (Ra ≤0.8µm), these pipes and fittings meet rigorous standards for:
- Food & Beverage: Dairy processing, brewery transfer lines, juice production.
- Pharmaceutical: Sterile API manufacturing, vaccine production.
- Cosmetics: Fragrance blending, essential oil pipelines.
- Beverage & Beer: CIP/SIP-compatible systems for wort, syrup, and carbonated drinks.
Why Choose Our Piping Systems?
Zero Contamination Risk
→ Seamless Design: Eliminates crevices where bacteria or product residues hide.
→ Electropolished Finish: Reduces adhesion and simplifies cleaning (CIP/SIP cycles).
Corrosion Resistance
→ 316L Grade: Withstands acidic cleaners (nitric acid), caustic solutions, and chlorinated sanitizers.
Regulatory Compliance
→ Full documentation for audits.
Easy Installation
→ Tri-Clamp, Weld, or Threaded connections for fast assembly.
Customer Success Stories

FAQs
Q: Are these pipes compatible with steam sterilization?
→ Yes! Rated for 250°F steam (400°F intermittent). Use PTFE gaskets for best results.
Q: Can I get custom diameters for niche applications?
→ Custom sizes (1/2" to 12") available with 10-day lead time.
Q: How do you ensure weld integrity?
→ Orbital TIG welding + 100% X-ray inspection for critical pharma/cosmetic lines.
