Product Features
Core Advantages
- Superior Corrosion Resistance: The PTFE lining ensures the joint resists most chemical media, including strong acids, alkalis, and oxidants, outperforming ordinary Rubber Joints in harsh chemical environments.
- High Structural Stability: SS304 Stainless Steel Flange enhances load-bearing capacity and rust resistance, extending service life compared to carbon steel flanged products.
- Excellent Flexibility: The rubber body provides good elasticity, effectively compensating for pipeline displacement caused by temperature changes and installation errors, reducing pipeline stress.
- Reliable Sealing: Integrated sealing structure with PTFE-rubber combination ensures zero leakage, avoiding media waste and safety hazards.
- Easy Installation: Lightweight design and standard flange connection simplify installation and maintenance, saving labor costs.
Product Principle
This
PTFE Lined Rubber Expansion Joint utilizes the elasticity of rubber to absorb pipeline displacements and vibrations, while the PTFE lining isolates the rubber from corrosive media, preventing rubber degradation. The SS304 flange ensures firm connection and structural stability, forming a comprehensive solution for chemical pipeline compensation and anti-corrosion.
How to Use the Product
Installation Steps
- Check the product appearance and dimensions to ensure they match the pipeline specifications, and confirm no damage during transportation.
- Clean the pipeline flange surface, removing oil, rust, and debris to ensure a tight seal.
- Align the joint flange with the pipeline flange, ensuring bolt holes are correctly positioned.
- Install bolts and nuts symmetrically, tightening them gradually with a torque wrench to ensure uniform force (avoid over-tightening to prevent flange deformation).
- After installation, conduct a pressure test to check for leakage; the joint can be put into use only if there is no leakage.
