Products Description
Need a smooth, crevice-free 45° elbow for your sanitary piping system?
Guanjiang's Sanitary 45° Pipe Fittings are precision-engineered components specifically designed for hygienic process systems. These specialized connectors facilitate the assembly of sanitary piping networks while maintaining product purity and process integrity. Manufactured from 316L stainless steel with electropolished finishes (Ra ≤ 0.38 μm) and conforming to 3-A, ISO, and DIN specifications, they provide smooth, crevice-free surfaces that prevent bacterial adhesion and facilitate thorough cleaning — ideal for pharmaceutical, food, dairy, and biotech applications.
Key Advantages
Electropolished surfaces (Ra ≤ 0.38 μm) inhibit microbial growth. Zero dead leg construction eliminates product entrapment. CIP/SIP compatible for effective cleaning and sterilization.
316L stainless steel construction withstands aggressive chemicals. Electropolished finish resists oxidation and chemical attack — suitable for high-purity and corrosive media.
Quick-clamp designs enable tool-free assembly. Precision machining ensures perfect alignment. Reduced installation time and labor costs.
Meets 3-A, FDA, EHEDG, and cGMP requirements. Full material traceability and documentation. Certified for food, pharmaceutical, and biotech applications.
Available as 45° elbows, 90° elbows, tees, reducers, couplings, and crosses — complete sanitary fitting portfolio.
Quick-clamp (Tri-Clamp) / Threaded / Weld-end / Butt-weld — fits your installation requirements.
1/2" to 8" (DN15 to DN200) — standard sanitary tube dimensions.

Sanitary Design Features:
Crevice-free construction: Smooth internal radius (R = 1.5 × tube OD) ensures no sharp corners or dead zones.
Full drainability: Self-draining design prevents liquid hold-up — essential for CIP cleaning.
Material traceability: Mill certificates (EN 10204 3.1) available for all sanitary fittings.
Polished finish: Electropolishing removes surface impurities and creates passive oxide layer for corrosion resistance.

Frequently Asked Questions
Q1: Why choose a 45° elbow instead of a 90° elbow?
A: A 45° elbow provides a gentler directional change than a 90° elbow — resulting in lower pressure drop and reduced risk of product shear or particle damage. It is preferred for sensitive fluids, viscous products, or when minimizing energy loss is critical.
Q2: What is the difference between weld-end and quick-clamp connections?
A: Quick-clamp (Tri-Clamp) — tool-free assembly, easy disassembly for cleaning (CIP), ideal for frequent changeovers. Weld-end — permanent connection, smoother internal surface (no gaskets), preferred for high-purity systems that do not require disassembly. Both are available for 45° elbows.
Q3: What surface finish is required for pharmaceutical applications?
A: For pharmaceutical applications (WFI, API processing), we recommend electropolished finish with Ra ≤ 0.38 μm (15 Ra). This meets ASME BPE and cGMP requirements, prevents bacterial adhesion, and supports complete drainability. Mill finish (Ra > 0.8 μm) is not acceptable for sanitary applications.
Q4: Are these fittings compatible with CIP and SIP processes?
A: Yes. The smooth, crevice-free internal surface and self-draining design make these fittings fully CIP (Clean-in-Place) and SIP (Steam-in-Place) compatible. No disassembly is required for cleaning — the fittings are designed to be cleaned in place with the rest of the piping system.
Q5: What documentation is provided with sanitary fittings?
A: We provide mill certificates (EN 10204 3.1) with material traceability, surface finish test reports, and dimensional inspection reports upon request. For pharmaceutical applications, we can provide validation documentation to support your qualification process.
