Product Description
EPDM DN25-DN300 Twin Sphere Carbon Steel Rubber Expansion Joint For Pump Pipe
Double Flange Vulcanized Carbon Steel Rubber Expansion Pipe Joint, also known as flexible single-ball rubber joints, rubber flexible joints, soft joints, shock absorbers, pipe shock absorbers, and shock absorber throats, is a highly flexible, airtight, medium-resistant, and weatherproof pipe joint solution.
Double ball rubber joints are available in various configurations including single ball, double ball, different diameter body, curved ball, and wind pressure coil. These tubular rubber pieces consist of inner and outer rubber layers, cord layers, and traveller components that are vulcanized and formed, then loosely combined with metal flanges or parallel joints.
Key Features
- Compact design with small size and light weight for easy installation and maintenance
- Excellent elasticity allowing lateral, axial, and angular displacement without restrictions from non-parallel flanges
- Superior noise reduction and vibration absorption capabilities during operation
- High-pressure resistance with balanced pipeline deviation, large displacement capacity, and convenient installation
Product Advantages
- Maintains airtightness under high pressure to ensure complete pipeline system sealing
- Compatible with various media including seawater, fresh water, hot/cold water, drinking water, sewage, crude oil, fuel oil, lubricating oil, finished oil, air, gas, steam, and granular powders
- Effective shock reduction and noise absorption with lightweight design for easy installation and maintenance
Selection Guide: 4-Step Quality Check
- Visual Inspection: Check for depressions in the inner wall - absence indicates proper expansion capability
- Odor Test: High-quality rubber joints should not have any pungent smell
- Weight Assessment: Premium joints are heavier, indicating sufficient material usage
- Durability Check: Small joints should support adult weight without collapsing when stepped on
