Union Type Rubber Flexible Joints Union Rubber Bellows – RUBASIA RUBBERTECH INDUSTRIES

At RUBASIA RUBBERTECH INDUSTRIES, our Union Type Rubber Flexible Joints (also known as Union Rubber Bellows or Rubber Expansion Joints) are designed with high-performance rubber materials and precision-engineered union ends to provide superior flexibility, vibration control, and durability.

They are widely used in industrial plants, HVAC systems, marine applications, water treatment plants, and building infrastructure across Sabah, Sarawak, and Brunei.

Detailed Product Features

1. High-Quality Rubber Body

• Made from premium elastomers such as EPDM, NBR, Neoprene, or Natural Rubber, tailored for specific applications (water, oil, chemical, seawater, or air systems).
• Resistant to aging, ozone, heat, and weathering, ensuring long-lasting performance even in tropical Borneo climates.

2. Reinforced Construction

• Built with multi-layer nylon cord fabric reinforcement for excellent strength and flexibility.
• Optionally reinforced with wire mesh for high-pressure or vacuum applications.
• Ensures resistance against bursting under sudden pressure surges (water hammer).

3. Threaded Union Ends

• Equipped with precision-machined threaded union ends (available in carbon steel, galvanized steel, stainless steel 304/316).
• Provides leak-proof, tight sealing for water, air, oil, or chemical pipelines.
• Easy connection and disconnection, especially for maintenance and replacement.

4. Vibration & Noise Reduction

• Effectively isolates vibration from pumps, compressors, chillers, and blowers.
• Reduces structure-borne noise, improving comfort in buildings, hotels, and hospitals.
• Extends equipment life by reducing operational stress.

5. Movement Compensation

• Absorbs axial movement, lateral displacement, and angular deflection caused by thermal expansion, contraction, or installation misalignment.
• Protects pipelines from cracks, leaks, and anchor damage.

6. Wide Temperature & Pressure Resistance

• Temperature Range: -20°C to +120°C (EPDM & NBR options).
• Pressure Rating: PN10 / PN16 (customized higher ratings available).
• Suitable for chilled water, hot water, compressed air, oil, seawater, and chemicals.

7. Compact & Space-Saving Design

• Short installation length, making it ideal for confined spaces such as machine rooms, basements, and ship engine compartments.
• Lightweight compared to flanged-type rubber expansion joints.

8. Corrosion & Chemical Resistance

• Stainless steel union ends provide corrosion protection for coastal and marine environments in Sabah, Sarawak, and Brunei.
• EPDM and Neoprene options resist acids, alkalis, ozone, and seawater.

9. Quick & Easy Installation

• Union type design allows fast installation without special tools.
• Perfect for small to medium pipe diameters (1/2” to 3”).
• Simplifies maintenance schedules by allowing quick disassembly.

10. Safety & Reliability

• Manufactured to international standards with rigorous testing for pressure, leakage, and vibration resistance.
• Protects entire piping systems by absorbing shocks and preventing costly breakdowns.
