Single Sphere Ansi 150LB Flange Flexible Neoprene EPDM Rubber Expansion Joint

Single Sphere Ansi 150LB Flange Flexible Neoprene EPDM Rubber Expansion Joint

Single ball rubber expansion joint (also known as single ball rubber soft joint, single ball rubber compensator) is a flexible connection element used in pipeline systems to absorb vibration, reduce noise and compensate for displacement.

Structure and composition
1. Ball part: single ball design, composed of inner and outer rubber layers and reinforcement layers (such as polyester cord), with high flexibility and elasticity.

2. Flange interface: usually equipped with metal flange (carbon steel, stainless steel, etc.) or threaded interface for easy installation.

3. Internal reinforcement: may contain wire rings or skeleton layers to improve pressure bearing capacity.

Main functions
Displacement compensation: absorb axial, lateral and angular displacement of pipelines (such as thermal expansion and contraction).

Vibration reduction and noise reduction: relieve vibration and noise generated by pumps, valves and other equipment.

Sealing and leak prevention: prevent medium leakage and adapt to pipeline misalignment.

Corrosion resistance: rubber material can adapt to a variety of chemical media.

Applicable fields

Water supply and drainage pipeline system:

Used in urban water supply and drainage, building water supply and drainage and other pipelines, it can compensate for the axial and lateral displacement of the pipeline, relieve the stress caused by temperature changes, foundation settlement and other factors, protect the safe operation of the pipeline system, and reduce the transmission of pipeline vibration and noise.

HVAC system:
It is often used in the chilled water, cooling water pipes and ventilation pipes of air conditioners. It can effectively compensate for the displacement caused by thermal expansion and contraction of pipes, prevent damage to pipe joints due to stress concentration, ensure the stable operation of the system, and play a certain role in shock absorption and noise reduction, improving the comfort of the indoor environment.
