Why Choose Food Grade EPDM Rubber Expansion Joints with PTFE Lining?
Food-grade EPDM rubber expansion joints with PTFE linings combine the flexibility of rubber with the excellent chemical resistance of PTFE.
This structure offers several advantages for industrial piping applications.
1. Excellent Chemical Resistance
The PTFE lining acts as a protective barrier between the conveyed fluid and the rubber body.
PTFE offers excellent resistance to a wide range of chemicals, including many acids, alkalis, and industrial fluids.
This makes PTFE lined rubber expansion joints suitable for applications where conventional rubber materials may not provide sufficient chemical resistance.
2. Food Grade EPDM Rubber Body
The expansion joint uses a food-grade EPDM rubber body, offering good flexibility, elasticity, and resistance to aging.
EPDM is commonly used in water treatment, food processing, and other industrial pipeline applications.
For applications involving direct food contact, material compliance and relevant certifications should be verified according to the customer’s specific requirements.
3. PTFE Inner Lining Protection
Unlike conventional rubber expansion joints, these products incorporate an internal PTFE lining.
The PTFE lining helps protect the rubber body from direct exposure to the conveyed medium and improves compatibility with various industrial fluids.
The lining design is particularly useful for pipeline systems requiring both flexibility and chemical resistance.
4. SS304 Stainless Steel Flanges
Each rubber expansion joint is equipped with SS304 stainless steel flanges manufactured according to the JIS B 2220 10K standard.
SS304 offers good corrosion resistance and is widely used in industrial piping systems.
The JIS 10K flange configuration allows connection to compatible Japanese-standard pipeline systems commonly found in Asian markets, including Indonesia.
5. Vibration and Noise Reduction
The single-arch rubber structure helps absorb vibration, reduce pipeline noise, and accommodate limited axial, lateral, and angular movements within the product’s rated design limits.
This can help reduce mechanical stress on connected piping equipment.
Customized Production for the Indonesian Market
For this order, the Indonesian customer required a customized rubber expansion joint combining food-grade EPDM material with an internal PTFE lining.
HONGZE PIPE supplied 50 pieces of DN50 PTFE lined rubber expansion joints, each featuring a face-to-face length of 105 mm and SS304 flanges with JIS 10K connections.
