Made of pure white food-grade rubber, this joint is specifically designed for pipelines in the food, beverage, pharmaceutical, and pure water industries that come into direct contact with food or clean media. It combines displacement compensation, vibration reduction, sealing, and hygiene compliance.
Layered design, all components meet food hygiene requirements:
1. Inner Rubber Layer: Pure white food-grade rubber, smooth inner wall with no dead corners, preventing material buildup, easy to clean, and in direct contact with the medium.
2. Reinforcing Skeleton Layer: Multiple layers of high-strength polyester/nylon fabric, enhancing pressure resistance and tensile strength, preventing deformation and bulging.
3. Outer Rubber Layer: White rubber of the same material, resistant to aging, impact, and external contamination, with a uniform pure white appearance.
Hygiene Compliance: Entirely white, free of carbon black and other harmful additives, certified for food contact safety, suitable for direct contact with food media.
Easy to clean and antibacterial: The smooth inner wall prevents material adhesion and residue buildup, making it suitable for the high-frequency cleaning requirements of the food industry.
Multi-dimensional compensation: Absorbs axial expansion and contraction, lateral misalignment, and angular deflection of the pipeline, compensating for installation errors and thermal expansion and contraction.
Vibration reduction and noise reduction: The flexible structure blocks the transmission of vibration from water pumps and conveying equipment, protecting pipelines and related equipment.
Reliable Sealing: The rubber has good elasticity, ensuring a tight seal at flange/clamp connections with no leakage.
Easy Visual Inspection: The white exterior allows for easy identification of leaks, damage, and mold, facilitating daily inspection and maintenance.
1. Food Processing: Beverage production lines, dairy workshops, grain and oil conveying, sauce/pastry ingredient pipelines
2. Beverage Industry: Mineral water, purified water, juice, beer, tea beverage conveying pipelines
3. Pharmaceutical Industry: Purified water, water for injection, sterile pharmaceutical solutions, pharmaceutical equipment connection pipes
4. Water Purification Industry: Pure water equipment, reverse osmosis systems, commercial direct drinking water pipelines
5. Cleanliness: The smooth inner wall is easy to clean; the black rubber inner wall is prone to dirt accumulation and cannot meet hygiene standards.
