Description
**Sanitary Stainless Steel Union: Nut,male and liner components
**Components & Terminology**
A sanitary stainless steel union (commonly referred to as a *Tri-Clamp Union* or *Hygienic Union*) is a detachable fitting designed for fast assembly and disassembly in sterile piping systems. Key components include:
1. **Union Body**: Machined from 316L/304 stainless steel with a polished interior (Ra ≤ 0.8 µm).
2. **Tri-Clamp Ferrule**: A two-part collar (*Clamp Hub* and *Clamp Segment*) secured by a single bolt for leak-proof sealing.
3. **Gasket/Seal**: Positioned between ferrules, typically made of EPDM, silicone, or PTFE.
4. **Sealing Surfaces**: Precision-machined *face seal grooves* to ensure flush alignment.
**Sealing Materials**
– **EPDM**: Cost-effective, temperature-resistant (-20°C to 135°C), ideal for general-purpose applications.
– **Silicone**: High flexibility, withstands extreme temperatures (-50°C to 200°C), suitable for CIP/SIP processes.
– **PTFE**: Chemically inert, compatible with aggressive media, low friction for easy cleaning.
**Product Features**
1. **Hygienic Design**: Smooth, crevice-free surfaces prevent bacterial buildup, meeting EHEDG/3-A standards.
2. **Quick-Connect Mechanism**: Tri-Clamp (ISO 2852) or DIN 11851 connections enable tool-free installation.
3. **Corrosion Resistance**: 316L grade resists pitting in chloride-rich environments (e.g., dairy, pharma).
4. **Temperature Adaptability**: Compatible with steam sterilization (up to 150°C) and cryogenic processes.
5. **Versatility**: Available in *full-bore* or *reduced-bore* designs to match flow requirements.
**Common Sizes & Configurations**
– **Sizes**: 1/2″ (DN15), 1″ (DN25), 2″ (DN50), 3″ (DN80).
– **End Types**: Butt-weld, threaded (NPT/BSP), or flanged connections.
**Compatible System Components**
1. **Piping**: *Sanitary tubing* (ASTM A270) with matching Tri-Clamp ferrules.
2. **Valves**: *Sanitary butterfly valves*, *diaphragm valves*, or *ball valves* with Tri-Clamp ends.
3. **Pumps**: *Centrifugal pumps* or *positive displacement pumps* integrated with union adapters.
4. **Instrumentation**: *Pressure gauges*, *flow meters*, and *temperature sensors* with hygienic fittings.
5. **Accessories**: *Inline strainers*, *sight glasses*, and *spray balls* for CIP systems.
**Typical Applications**
– Fluid transfer in breweries, dairy processing, and biopharmaceutical reactors.
– Vacuum lines for food packaging or laboratory equipment.
– Modular systems requiring frequent disassembly for cleaning or reconfiguration.
**Advantages Over Traditional Fittings**
– Minimizes downtime with rapid assembly.
– Reduces contamination risk through seamless design.
– Compatible with automated cleaning systems (CIP/SIP).
Product Packaging Instructions：
Each product is first individually packaged in a foam bag, then carefully placed into a designated carton. Finally, it is palletized or packed in an export wooden crate. The entire packaging process is rigorously executed to prevent any damage during transportation.
