Description

Key Features & Material Specifications

316L Stainless Steel Construction

• Superior corrosion resistance, especially against chlorides and organic acids
• Low‑carbon formulation minimizes carbide precipitation during welding
• Ideal for high‑purity and welded systems

Hygienic Surface Finishes

Mechanical Polish (MP): Ra ≤ 0.8 µm  

• Suitable for food, dairy, beverage, and general sanitary applications

Electropolish (EP): Ra ≤ 0.4 µm  

Ultra‑smooth, mirror‑like finish for pharmaceutical and biotech systems

• Reduces microbial adhesion and enhances cleanability

Industry‑Standard Compliance

Sanitary fittings are manufactured to meet major global standards, including:

• ASME BPE (Bioprocessing Equipment)
• ISO 2852
• DIN sanitary standards
• 3‑A Sanitary Standards

These standards ensure dimensional accuracy, traceability, and hygienic design.

Connection Types

• Tri‑Clamp (Tri‑Clover) — quick‑release, leak‑proof, industry standard
• Butt Weld — ideal for permanent, high‑purity systems
• Bevel Seat — common in dairy and beverage applications
• Other sanitary connection formats available upon request

Frequently Asked Questions

Why is 316L stainless steel preferred for sanitary fittings?

316L offers superior resistance to pitting and crevice corrosion, especially in environments containing chlorides or acidic cleaning agents. The low‑carbon grade prevents weld decay, ensuring long‑term integrity in welded systems.

Should I choose Mechanical Polish or Electropolish?

Mechanical Polish (Ra ≤ 0.8 µm):  

• Ideal for food, beverage, and general sanitary applications.

Electropolish (Ra ≤ 0.4 µm):  

Recommended for pharmaceutical, biotech, and high‑purity water systems.

• Provides enhanced corrosion resistance and reduced microbial retention.

How important is gasket selection?

Critical. Gaskets are part of the wetted surface and must match your process conditions.

• EPDM: Hot water, steam, mild acids
• Silicone: High‑temperature applications

PTFE: Aggressive chemicals and ultra‑pure systems

• Always ensure FDA or EC compliance for food and pharmaceutical use.

Are these fittings suitable for WFI or purified water systems?

Yes. For high‑purity water systems, specify:

• Electropolished finish (Ra ≤ 0.4–0.5 µm)
• ASME BPE compliance
• Full material traceability
• Orbital‑weld butt‑weld connections

These requirements help maintain low microbial counts and prevent particle shedding.

What documentation is provided?

Sanitary fittings can be supplied with:

• Material Test Certificates (MTCs) verifying chemical composition
• Certificates of Conformance (CoC)
• Traceability documentation for pharmaceutical and biotech validation

Documentation packages are available upon request.
