High Pressure Resistant Flange Rubber Flexible Joint Double Ball Expansion Joint Buckle Groove Rubber Joint
A Double Ball Expansion Joint with a Buckle Groove Rubber Joint typically refers to a type of flexible pipe fitting used to absorb movement and vibration in pipelines, ensuring minimal stress on the connected pipes.
The "double ball" design refers to the two rubber spheres that help the joint flex and accommodate movement in both axial and lateral directions, while the "buckle groove" feature allows for an easier connection between components, usually through grooves that lock the joint in place securely.
Here’s a breakdown of its key features:
1. Double Ball Design
Consists of two spherical rubber sections connected by a middle pipe, providing enhanced flexibility.
Allows for greater angular deflection and multi-directional movement compared to single-ball joints.
2. Buckle Groove (Flanged or Clamped Connection)
Features grooved ends for secure connection using clamps or flanges, ensuring a tight seal.
Common in HVAC, water supply, and industrial piping for easy installation and disassembly.
3. Rubber Material
Typically made of EPDM, NBR, or Neoprene for resistance to water, heat, chemicals, and abrasion.
Reinforced with fabric or steel wire for added pressure resistance.
Double Sphere Rubber Joint Advantages
1.High flexibility for complex movements.
2.Leak-proof with proper installation.
3.Durable under high pressure and temperature.
Common Standards
ISO 9001, ASTM, DIN, BS, or AWWA compliant, depending on the application.
