KST Molded Double Sphere Bellows
The KST molded double-sphere rubber expansion joint features a single arch and is molded, specifically designed to withstand the most demanding piping system configurations.It allows for axial compression or extension, lateral deflection, as well as angular movement. Its easy installation makes it the ideal choice for tackling challenging tasks.

What is the molded double sphere bellows?
The characteristics of the double-sphere rubber expansion joint include:
Strong Displacement Compensation: The double-sphere design effectively absorbs thermal expansion and contraction in the pipeline, providing significant displacement compensation.
Pressure Resistance: It can withstand high pressure, making it suitable for high-pressure pipeline systems and ensuring safe operation.
Vibration and Noise Reduction: The rubber material offers excellent vibration and noise reduction, effectively minimizing vibration and noise, enhancing system stability and comfort.
Corrosion Resistance: The materials possess good corrosion resistance, allowing for long-term use in acidic, alkaline, and salt spray environments, thereby extending service life.
Easy Installation: The reasonable design allows for quick and easy installation without the need for special tools, reducing construction time and costs.
Wide Applicability: It is suitable for various industries, including chemical, petroleum, food, pharmaceuticals, and HVAC, capable of transporting various media.

Designs
The rubber expansion joint mainly consists of two parts: the rubber body and the metal flange. The rubber body typically includes three layers: the inner rubber layer, the reinforcement layer, and the outer rubber layer. Different rubber materials can be customized based on the medium being used. The flange can also be customized to different standards and materials according to customer requirements.
