Product Description
Product Overview
The double-ball rubber expansion joint utilizes high elasticity, superior airtightness, medium resistance, weather resistance, and radiation resistance properties of rubber to effectively reduce pipeline vibration and noise while compensating for thermal expansion and contraction caused by temperature variations.
Construction Components
- Inner Rubber Layer: Direct contact with pipeline for sealing and protection
- Reinforcement Layer: Multi-layer nylon cord fabric for enhanced strength and durability
- Cover Layer: Outer protection enhancing airtightness and durability
- Metal Flanges: Connection components ensuring proper installation and sealing
Installation Guidelines
- Never exceed displacement limits during installation
- Install bolts symmetrically with gradual pressure tightening
- For pressures above 0.6MPa, use elastic pressure pads on bolts
- Vertical installations require force support and anti-pull-off devices
- Keep away from heat sources, ozone areas, and strong radiation
- Avoid sharp instruments during handling and installation
