Clamping pipe coupling

quick-releasequick-coupling304 stainless steel

Product Overview
Precision-engineered hygienic Tri‑Clamp connection systems for pharmaceutical, biotech, and food processing. DIN 32676, ASME BPE, and 3‑A compliant assemblies delivering sterile, leak‑proof seals with rapid assembly/disassembly for CIP/SIP operations. Electropolished ferrule surfaces (Ra ≤ 0.8 µm) and external clamp compression eliminate crevices and enable full cleanability while meeting EU GMP and FDA hygienic design requirements.

Key Benefits

• Rapid connection/disconnection: Tool‑free clamp operation enables equipment disassembly in seconds for cleaning validation, maintenance, or process reconfiguration without specialized tools.
• Crevice‑free hygienic design: Smooth electropolished surfaces (Ra ≤ 0.8 µm) with no dead legs, threads, or gasket compression grooves eliminate bacterial entrapment sites and enable complete CIP/SIP efficacy.
• Validated seal integrity: Precisely controlled compression on FDA‑compliant gaskets creates reliable, leak‑free seals validated for process pressures, thermal cycles, and aggressive cleaning chemistries.
• Regulatory compliance and traceability: Heat numbers and EN 10204 3.1/3.2 material certificates; conformity to DIN 32676, ASME BPE, 3‑A Sanitary, and EHEDG.
