High-Performance Single Sphere Rubber Flexible Joints for Borneo's toughest Applications

Introduction: Engineering Resilience for Borneo's Climate and Industry

RUBASIA RUBBERTECH INDUSTRIES is the premier supplier of advanced pipeline solutions across Malaysia and Brunei. Our Single Sphere Rubber Flexible Joint with Ductile Iron Floating Flanges is engineered to meet the specific demands of Borneo's diverse climate and industrial landscape. From the high-humidity coastal regions of Labuan and Sandakan to the industrial heartlands of Bintulu and Kerteh, and the urban developments in Kota Kinabalu, Kuching, and Bandar Seri Begawan, our product ensures system integrity, reduces maintenance costs, and enhances operational longevity.

 

Detailed Product Overview & Specifications

This component is a precision-engineered pipe connector designed to absorb multiple forms of stress in piping systems.

Key Technical Data:

• Product Name: Single Sphere Flexible Rubber Joint (Also known as Rubber Expansion Joint, Vibration Absorber)
• Connection Type: Ductile Iron Floating Flanges (Vanstone Type)
• Size Range: 2” (DN50), 3” (DN80), 4” (DN100), 6” (DN150), 8” (DN200), 10” (DN250), 12” (DN300)
• Rubber Material: EPDM (Ethylene Propylene Diene Monomer)
• Flange Standards: Table E, JIS 10K, ANSI 150, and PN16
• Flange Material: Ductile Iron (Grade 500-7) with Electroplated Coating for corrosion resistance.

 

In-Depth Key Features & Engineering Benefits

 

1. Superior Spherical Design for Multi-Directional Movement

• Axial Compression/Extension: Compensates for thermal expansion and contraction in long pipeline runs, common in exposed industrial pipe bridges in Miri or Lahad Datu.
• Lateral Offset: Accommodates misalignment and settling in pipe supports, a critical feature for projects in areas with variable soil conditions.
• Angular Deflection: Absorbs directional changes at pipe connections, preventing stress concentration.

 

2. Ductile Iron Floating Flanges for Unmatched Installation Ease

• 360-Degree Rotation: The flanges rotate independently of the rubber body, eliminating the need for precise bolt hole alignment during installation. This drastically reduces labour time for contractors across Sabah and Sarawak.
• Vanstone Profile: The flanges are designed to match standard drilling patterns, ensuring compatibility with existing valves and pipes in plants from Sibu to Kuala Belait.

 

3. Advanced Vibration & Noise Absorption

• The natural damping properties of EPDM rubber isolate and dissipate energy from pumps, chillers, and compressors. This is essential for:
  • Hotel and Hospital HVAC systems in urban centres like Kota Kinabalu and Bandar Seri Begawan.
  • Industrial processing plants in Bintulu and Samalaju Industrial Park.

 

4. Robust, Reinforced Construction for Long Service Life

• Internal Steel Wire Reinforcement: Embodied within the rubber, it provides high pressure ratings and prevents the joint from over-extending and pulling apart.
• Nylon Cord Fabric Ply: Multiple layers of high-tensile nylon cord are bonded with the rubber, providing exceptional burst pressure resistance and dimensional stability under vacuum conditions.

 

5. EPDM Elastomer: The Ideal Material for Borneo

• Excellent Heat Resistance: Suitable for continuous operation with water up to 110°C, perfect for steam lines and hot water circuits.
• Weather & Ozone Resistance: EPDM offers superior performance against Borneo's intense sun, humidity, and tropical rainfall, making it ideal for outdoor installations from Tawau to Brunei-Muara.
• Good Chemical Resistance: Resists water, steam, alkalis, and mild acidic solutions, commonly found in water treatment and cooling systems.

 

Detailed Applications by Industry & Location

 

1. Water & Wastewater Treatment

• Use Case: Installed at pump inlets/outlets to dampen water hammer and isolate vibration.
• Borneo Locations: Kuching Water Treatment Plant, Labuan desalination facilities, Seria municipal water systems, and plants serving Sandakan and Sibu.

 

2. Heating, Ventilation & Air Conditioning (HVAC)

• Use Case: Connecting chillers, cooling towers, and air handling units (AHUs) in commercial buildings.
• Borneo Locations: Major shopping malls in Kota Kinabalu, government complexes in Bandar Seri Begawan, hospitals in Miri, and office towers across the region.

 

3. Industrial & Process Engineering

• Use Case: Handling chemicals, slurries, and process water in plants. Compensating for thermal growth in high-temperature pipelines.
• Borneo Locations: Oil & gas facilities in Kimanis and Kuala Belait, palm oil mills in Lahad Datu and Bintulu, and manufacturing plants in Samalaju.

 

4. Marine & Offshore

• Use Case: Used for seawater cooling lines, ballast systems, and engine room piping on vessels and offshore platforms.
• Borneo Locations: Shipyards in Labuan and Muara, supply vessels operating from Kota Kinabalu port, and offshore platforms in the South China Sea.
