Single Sphere Rubber Flexible Joint with Floating Flanges – Borneo Supply (Sabah, Sarawak, Brunei)

Supplier: RUBASIA RUBBERTECH INDUSTRIES

 

The Single Sphere Rubber Flexible Joint with Floating Flanges is one of the most important components in modern piping systems across Sabah, Sarawak, and Brunei. Engineered with a spherical EPDM rubber body reinforced with nylon cord and steel wire, and equipped with rotating floating flanges, this joint delivers maximum flexibility, reliability, and durability in industrial, marine, and building service applications.

 

Detailed Product Features

1. Single Sphere (Single Arch) Rubber Body

• Compact design: Unlike double-sphere joints, the single sphere joint requires less space, making it ideal for tight installations in HVAC rooms, pump stations, and ship engine rooms.
• High flexibility: Allows axial compression, axial extension, lateral displacement, and angular deflection.
• Uniform stress distribution: The spherical shape disperses pressure evenly, reducing risk of localized wear.

 

2. EPDM Rubber Construction

• Heat resistance: Handles temperatures from -20°C to +120°C, perfect for hot water, chilled water, and mild steam.
• Chemical resistance: EPDM withstands mild acids, alkalis, ozone, seawater, and weathering—making it suitable for coastal and offshore towns in Sabah (Kudat, Semporna, Sipitang, Kota Kinabalu) and Brunei (Kuala Belait, Seria, Bandar Seri Begawan).
• Long lifespan: Resistant to cracking, hardening, and UV degradation even in tropical Borneo climates.

 

3. Reinforced Internal Structure

• Nylon cord reinforcement strengthens the rubber body, preventing elongation under internal pressure.
• Steel wire reinforcement provides resistance to vacuum and high pressure, preventing the joint from collapsing or bursting.
• Pull-off protection: Withstands sudden pressure surges, protecting pumps and pipelines.

 

4. Floating (Vanstone) Flanges

• Rotatable design: Flanges can rotate freely, allowing perfect bolt alignment without rotating the entire joint.
• Material options: Available in Mild Steel (MS) for cost-effectiveness or Stainless Steel 304 (SS304) for marine, offshore, and chemical applications.
• Multiple standards supported: JIS 10K, ANSI 150, PN16, and Table E—ensuring compatibility with regional pipelines across Kuching, Miri, Sibu, Sandakan, Tawau, and Bandar Seri Begawan.

 

5. Vibration and Noise Absorption

• Reduces mechanical vibration from pumps, compressors, and motors in HVAC systems (Kota Kinabalu, Kuching, Bandar Seri Begawan).
• Prevents vibration transfer to building structures, reducing wear on pipelines and ensuring quieter operation.
• Ideal for residential water supply systems in Ranau, Tenom, Beaufort, Bau, Simunjan, and Gadong where low noise levels are critical.

 

6. Thermal Expansion & Misalignment Compensation

• Absorbs thermal expansion in hot and cold water systems, preventing cracks and leaks in industrial plants in Bintulu, Kapit, Sarikei, Lahad Datu.
• Compensates for installation misalignments, eliminating costly realignment of flanges and pipelines.
• Protects equipment such as pumps, boilers, and heat exchangers from stress damage.

 

7. High Pressure & Vacuum Capability

• Suitable for high-pressure pipelines up to 16 bar.
• Can handle vacuum conditions with proper installation, making it suitable for chemical plants and marine suction lines in Miri, Limbang, Lawas, and Kuala Belait.

 

8. Safety and Reliability

• Designed to withstand water hammer effects, protecting downstream valves and pumps.
• Fire-resistant outer rubber option available for oil & gas projects in Brunei and Sarawak.
• Meets international pipeline standards for industrial reliability.

 

Why These Features Matter for Borneo (Sabah, Sarawak, Brunei)

• Sabah: Coastal towns like Sandakan, Semporna, Kudat need EPDM joints resistant to seawater corrosion.
• Sarawak: Industrial hubs like Miri, Bintulu, Kapit require high-pressure reinforced joints for oil & gas and palm oil mills.
• Brunei: Urban centers like Bandar Seri Begawan, Seria, Kuala Belait demand vibration-damping joints for HVAC, petrochemical, and water infrastructure.
