Product Features
Key Advantages & Technical Highlights
- Superior Corrosion Resistance: The PTFE lining features non-stick, acid and alkali resistant properties, effectively isolating corrosive sewage from the rubber body, extending product service life compared to ordinary Rubber Joints.
- Excellent Vibration Reduction: As a Vibration Reducing PTFE Rubber Expansion Joint, it utilizes the elastic properties of rubber to absorb vibration from pumps, valves, and other equipment, reducing noise and protecting pipeline connections.
- Strong Sealing Performance: Adopts integrated molding technology, ensuring tight connection between PTFE lining and rubber body, no leakage even under high pressure and frequent displacement.
- Durable Construction: High-quality rubber material resists aging, wear, and hydrolysis, while the reinforced flange design enhances load-bearing capacity, suitable for long-term heavy-duty operation.
- Easy Installation & Maintenance: Lightweight design and standard flange connection allow quick installation, no special tools required; low maintenance cost with long service cycle.
Difference from Competitors
Unlike ordinary rubber joints without PTFE lining, our product is specifically engineered for sewage treatment environments, solving corrosion problems that plague traditional products. We use high-purity PTFE lining instead of recycled materials, ensuring consistent performance. Additionally, our
PTFE Lined Rubber Expansion Joints undergo strict pressure testing and aging tests, with a 10-year mechanical warranty, which is longer than the industry average of 5-7 years.
How to Use the Product
Installation Steps
- Prepare the pipeline sections to be connected, ensuring flange surfaces are clean, flat, and free of burrs or debris.
- Align the product with the pipeline flanges, ensuring the PTFE lining is not twisted or folded; insert bolts through flange holes symmetrically.
- Tighten the bolts gradually in a crisscross pattern to ensure uniform pressure, avoiding over-tightening which may damage the rubber body or PTFE lining.
- Check the alignment and sealing performance after installation; conduct a pressure test (1.5 times the working pressure) to confirm no leakage.
- Regularly inspect the joint for signs of aging, deformation, or leakage during use; replace if any damage is found.
Application Scenarios
Our PTFE Rubber Joint for Sewage Treatment Plant is widely applied in various links of sewage treatment systems, including:
- Sewage Collection Pipes: Compensates for thermal expansion and vibration in municipal sewage collection pipelines, resisting corrosion from domestic and industrial sewage.
- Treatment Tanks & Pumps: Installed between pumps, aerators, and treatment tanks to reduce equipment vibration and protect tank connections.
- Chemical Sewage Treatment: Suitable for industrial sewage treatment (e.g., printing, dyeing, chemical plants) with strong corrosive components.
- Sludge Disposal Systems: Adapts to the harsh environment of sludge transportation, resisting abrasion and corrosion from sludge impurities.
- Water Recycling Equipment: Used in reclaimed water treatment pipelines, ensuring water quality safety with food-grade PTFE lining.
Customer Value: This product reduces pipeline maintenance frequency by 40%, lowers replacement costs, and improves the stability of sewage treatment systems. Its corrosion resistance avoids pipeline leaks, preventing environmental pollution and potential fines, while vibration reduction extends the lifespan of associated equipment (e.g., pumps, valves) by 30%.
