Sanitary Flexible Connector For Food And Beverage Systems
Food grade rubber expansion joints ensure hygienic, flexible connections in food and beverage piping, offering corrosion resistance and vibration control for sanitary applications.
Food Grade Rubber Expansion Joint, also known as a sanitary rubber joint or flexible connector, is a specialized component designed for food processing piping systems. These joints are crafted from FDA-approved elastomers such as silicone, white EPDM, or white NBR, reinforced with nylon cord or stainless steel (SS316) flanges, ensuring corrosion resistance and compliance with stringent hygiene standards. They are ideal for applications in food and beverage, pharmaceutical, and clean water systems, providing hygienic piping protection by absorbing vibration, reducing noise, and compensating for thermal expansion.
This rubber expansion joint is food safe, made of FDA approved EPDM rubber material and offers great resistance to oils and greases. The food safe rubber expansion joint is suitable for foodstuff, good for pulps, flour, juices and wines.. The base material for the food safe rubber expansion joint White Ethylene Propylene Diene Monomer.
The food grade rubber expansion joint features a flexible bellows design that accommodates axial, lateral, and angular movements, minimizing pipeline stress from temperature changes or mechanical vibrations. Available in sizes from 1” to 24” (DN25 to DN600) with pressure ratings up to 25 bar, these joints operate in temperatures from -15°C to 120°C, depending on the material. Their non-toxic, odorless construction ensures product purity, while PTFE linings or stainless steel flanges enhance corrosion resistance, making them suitable for handling foodstuff like juices, wines, pulps, and oil-containing products in sanitary pipeline solutions.
Manufactured through high-pressure vulcanization, food grade rubber expansion joints undergo rigorous testing, including pressure, burst, and hygiene compliance tests, to meet standards like FDA, RAL, and WRAS. Their high elasticity reduces noise by up to 20 decibels and mitigates pipeline wear, extending system lifespan. These joints support flanged or threaded connections, offering versatility for food processing plants, breweries, and pharmaceutical facilities. The use of food-grade silicone or EPDM ensures resistance to bacteria and chemicals, maintaining sanitary conditions.
Compared to standard rubber expansion joints, food grade rubber expansion joints are specifically engineered for hygienic applications, prioritizing non-toxic materials and ease of cleaning. Their lightweight design and simple installation reduce maintenance costs, while materials like white NBR provide excellent resistance to oils and greases, ideal for food processing environments. These joints are less suited for extreme high-temperature applications but excel in hygienic piping protection where cleanliness and flexibility are critical.
Food grade rubber expansion joints address challenges like pipeline stress, corrosion, and contamination in food and beverage systems. Their sanitary, corrosion-resistant design makes them a reliable choice for engineers seeking safe, durable food processing piping solutions, ensuring compliance with health standards and operational efficiency.
