Product Parameter Description for Stainless Steel Sanitary-Grade Bellows-flexible pipe
Tailored for high-purity industries such as food, pharmaceuticals, and biotechnology, the stainless steel sanitary-grade bellows are crafted from premium AISI 316L stainless steel, offering exceptional corrosion resistance, fatigue durability, and hygienic performance. Below are the core technical specifications:
——
Connection Methods
1. Quick-Install Clamp Connection (Tri-Clamp Style)
• Features a sanitary clamp with sealing gasket, compliant with DIN, SMS, ISO, and other standards, enabling rapid assembly/disassembly for easy cleaning and maintenance.
• Seal materials include silicone, EPDM, or PTFE, all FDA/EC-compliant, accommodating pipe diameters from DN15 to DN150.
2. Flange Connection
• Flange types include DIN, GB (Chinese Standard), ANSI (American Standard), etc., with 316L stainless steel flange bodies and optional mirror (Ra≤0.8μm) or brushed surface finishes.
• Suitable for high-pressure or large-diameter pipeline systems, with flat sealing surfaces and food-grade gaskets ensuring leak-proof performance.
3. Threaded Connection
• Offers internal (BSP, NPT, etc.) or external thread connections for small-diameter pipes (DN6-DN50), with simple installation.
• Conical seals or PTFE tape can be applied to threads for enhanced airtightness in tight spaces.
——
Performance Parameters
• Operating Pressure: Standard range 0.6–1.6 MPa, with customizable high-pressure models (up to 3.0 MPa).
• Operating Temperature: -50°C to +300°C (temperature limits vary by seal material):
• EPDM gasket: -20°C to +150°C
• Silicone gasket: -50°C to +200°C
• PTFE gasket: -50°C to +260°C
• Compatible Media:
• Liquids: Water, acid-base solutions, dairy products, pharmaceutical fluids, etc.
• Steam: Saturated or high-temperature steam (requires temperature-resistant seals).
• Viscous/Particulate Media: Jams, slurries, or fluids with minor solids; the smooth inner wall (Ra≤0.6μm) minimizes residue.
——
Structure & Sanitary Certifications
• Bellows Structure: Multi-layer stainless steel bands hydraulically formed into a flexible design, compensating for thermal expansion/contraction and vibrational displacement with a minimum bending radius of ≥3× pipe diameter.
• Certifications: Conforms to FDA 21 CFR, EHEDG, and 3-A Sanitary Standards, supporting CIP/SIP (Clean-In-Place/Sterilize-In-Place) processes.
——
Applications: Dairy processing, bioreactor connections, pharmaceutical fluid transfer, high-temperature steam pipelines, and other scenarios requiring hygiene and reliability. Users may select appropriate connection types and seal materials based on medium properties, pressure/temperature conditions, and installation requirements.

Key Translation Insights:
1. Industry-Specific Terminology:
•sanitary-grade” (emphasizing hygiene standards), “CIP/SIP” → “Clean-In-Place/Sterilize-In-Place” (retaining acronyms for technical precision).
2. Technical Precision:
•”hydraulically formed” (accurate mechanical process translation), ” “minimum bending radius of ≥3× pipe diameter” (quantitative clarity).
3. Regulatory Compliance:
• “FDA 21 CFR, EHEDG, 3-A” → listed as-is (global industry standards require direct citation for credibility).
4. Audience Adaptation:
• Maintained technical depth while avoiding jargon overload (e.g., “multi-layer stainless steel bands” instead of overly literal translations).
