The Hygienic Stainless Steel B-Type Clamp Joint is a premium pipe fitting designed for quick, sanitary connections in food, beverage, and pharmaceutical systems. Constructed from 316L stainless steel, this clamp joint features a tri-clamp (tri-lobe) design (ISO 2852 compliant), enabling tool-free assembly/disassembly while maintaining aseptic conditions.
Aseptic Design & Construction:
316L stainless steel (extra low carbon) with electropolished surface (Ra ≤0.4μm), eliminating crevices and particle traps, compliant with 3-A Sanitary Standards and FDA 21 CFR Part 177.
B-type clamp (conical seat) ensures bubble-tight seals without dead legs, critical for clean-in-place (CIP) and steam-in-place (SIP) processes.
Tool-Free Installation:
Tri-clamp connection (ISO 2852) allows assembly/disassembly in seconds using a single clamp, reducing downtime by 70% during maintenance and product changeovers.
Compatible with O-ring or flat gaskets (EPDM, silicone, PTFE), with gasket grooves designed to prevent extrusion under pressure (up to 10 bar).
Hygienic Performance:
Smooth internal surface (Ra ≤0.8μm) minimizes product residue buildup, ideal for viscous fluids like dairy, sauces, and pharmaceutical slurries.
Temperature range: -40°C to 200°C (with PTFE gaskets), suitable for hot water sanitization and cryogenic ingredient handling.
Compliance & Certification:
Meet ISO 22000, cGMP, and EU GMP guidelines, with material traceability and surface roughness reports available for audit purposes.
Available in sizes 1/2" to 12" (DN15-DN300), with optional FDA-compliant lubricants for gasket installation in food-grade systems.
Perfect for sanitary fluid handling in critical industries:
Food & Beverage: Connecting pasteurizers, mixers, and filling machines in breweries, dairies, and juice processing plants, ensuring no product contamination.
Pharmaceutical Manufacturing: Aseptic connections in bioreactors, filtration systems, and sterile filling lines, compliant with USP Class VI and EP 3.1.2 standards.
Cosmetics & Personal Care: Transferring lotions, creams, and fragrances, with electropolished surfaces preventing ingredient degradation and bacterial growth.
Biotech Research: Laboratory-scale bioprocessing systems, where quick disassembly is essential for frequent cleaning and component replacement.
Q: What is the difference between A-type and B-type clamp joints?
A: B-type (conical seat) is ideal for high-purity systems with CIP/SIP, while A-type (flat seat) is used for general industrial applications without strict aseptic requirements.
Q: Can the clamp joint be used with non-stainless steel pipes?
A: Yes, but use a dielectric gasket to prevent galvanic corrosion when connecting to carbon steel or aluminum pipes.
Q: How often should the gasket be replaced in CIP systems?
A: Replace gaskets every 6-12 months or after 100 SIP cycles, depending on media aggressiveness and temperature exposure.
Q: Is the clamp joint suitable for vacuum applications?
A: Yes, the conical seat provides reliable sealing down to 29" Hg vacuum; use a metal-reinforced gasket for extreme vacuum conditions.
