Rubber Joint FAQ
What is the typical lifespan of a rubber joint?
The lifespan of a rubber joint depends on several factors including operating conditions, media being transported, pressure, and temperature. Under normal conditions, our standard rubber joints typically last 5-7 years. High-quality EPDM rubber joints in moderate conditions can last up to 10 years. Regular inspections are recommended to monitor for signs of wear, cracking, or deformation.
How do I select the right rubber material for my rubber joint?
Material selection for your rubber joint depends on the media, temperature, and environmental conditions:
- EPDM: Best for hot water, steam, and mild chemicals
- NBR: Excellent for oils and petroleum products
- CR: Good for weather resistance and moderate chemicals
- NR: Provides superior flexibility for vibration absorption
- FKM: For aggressive chemicals and high temperatures
Our technical team can help specify the ideal material for your specific application.
Can rubber joints be used for high-pressure applications?
Yes, our rubber joints are available in reinforced designs that can handle pressures up to PN40 (Class 300). For high-pressure applications, we recommend:
- Multiple fabric reinforcement layers
- Steel ring reinforcement for flanges
- Special high-pressure design configurations
All high-pressure rubber joints undergo rigorous testing to ensure safety and performance at rated pressures.
Installation and Maintenance Guidelines
Proper installation extends the service life of your rubber joint:
- Never exceed the stated movement capacities
- Install without torsion or twisting
- Ensure proper alignment of piping systems
- Use appropriate gaskets and fasteners
- Periodically inspect for signs of wear or deterioration
