Double Sphere EPDM Rubber Flexible Joint with Floating Flanges for Maximum Pipeline Performance in Borneo

The Superior Solution for Complex Piping Movements

RUBASIA RUBBERTECH INDUSTRIES provides advanced pipeline protection solutions for the challenging environments of Borneo. Our Double Sphere Rubber Flexible Joint with Floating Flanges is engineered to offer unparalleled movement absorption and vibration dampening, far exceeding the capabilities of standard single sphere joints. Designed for the rigorous demands of industrial, marine, and municipal applications across Sabah, Sarawak, and Brunei, this joint is the definitive choice for ensuring the longevity and reliability of your piping systems.

Detailed Product Specifications & Technical Data

• Product Name: Double Sphere Rubber Flexible Joint (Double Arch Expansion Joint)
• Connection Type: 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) - Ideal for hot water, steam, and weather resistance.
• Flange Standards: Table E, JIS 10K, ANSI 150, and PN16.
• Flange Material Options:
  • Mild Steel (Electroplated): A cost-effective choice for standard industrial and plumbing applications with good corrosion protection.
  • Stainless Steel 304: Highly recommended for corrosive environments, including marine applications, chemical plants, and coastal areas like Labuan, Muara, and Sandakan.

In-Depth Engineering & Design Advantages

1. Dual-Sphere Architecture for Enhanced Performance
The two-arch design is not just an incremental improvement; it's a fundamental enhancement that provides critical benefits for Borneo's infrastructure:

• Increased Movement Capacity: Offers approximately double the axial compression and extension and significantly greater lateral and angular movement compared to a single sphere joint. This is crucial for long-distance pipelines and structures in areas prone to minor settlement.
• Lower Spring Rate: The dual-sphere design provides greater flexibility with less force, resulting in markedly reduced stress transmission to pumps, valves, and adjacent pipe supports. This is vital for protecting sensitive equipment in water treatment plants from Kuching to Kota Kinabalu.
• Superior Flow Dynamics & Self-Cleaning Action: The smooth, continuous double-arch profile minimizes turbulence, reduces pressure drop, and prevents the accumulation of sediments and debris. This "scouring" action is essential for maintaining efficiency in raw water and wastewater systems.

2. Robust, Multi-Layer Reinforced Construction
The joint's durability is built from the inside out:

• High-Tensile Nylon Cord Fabric: Multiple layers of cord are embedded circumferentially within the EPDM, providing exceptional resistance to internal pressure and preventing ballooning under load.
• Internal Steel Reinforcement Ring: A critical component embedded at the flange interface that provides mechanical strength, prevents joint pull-off, and ensures a secure seal under vacuum conditions and high pressure surges.
• Full-Arch Steel Wire: A continuous steel wire is molded into each arch of the sphere, reinforcing the structure and defining its shape under negative pressure, ensuring it does not collapse.

3. Advanced Floating Flange System with Material Choice
The flange is as engineered as the rubber body itself:

• 360-Degree Rotating Flanges: The "floating" or "vanstone" design allows independent rotation of each flange, making bolt hole alignment effortless during installation. This feature is a significant time-saver for contractors working on complex pipe racks in industrial plants in Bintulu or tight mechanical rooms in Bandar Seri Begawan.
• Material Selection for Specific Environments:
  • Mild Steel Flanges: Coated with an electroplated layer (e.g., zinc), these are suitable for general use in internal plumbing, HVAC, and non-corrosive industrial applications.
  • Stainless Steel 304 Flanges: The premium choice for coastal and marine projects in Labuan and Brunei Bay, as well as for chemical plants and water treatment facilities where corrosion resistance is paramount. SS304 provides exceptional longevity against the humid, saline atmosphere of Borneo.

Detailed Application Scenarios in Borneo

1. Water & Wastewater Infrastructure

• Use Case: Installed on the suction and discharge sides of pumps to absorb vibration and compensate for thermal expansion in pipelines.
• Borneo Locations: Municipal water projects in Kuching, sewage treatment plants in Kota Kinabalu, and drainage systems in Sibu and Miri.

2. Heavy Industry & Manufacturing

• Use Case: Protecting piping in chemical processing, palm oil mills, and power generation facilities from stress induced by equipment vibration and thermal cycling.
• Borneo Locations: Industrial zones in Samalaju, Bintulu, Lahad Datu, and Seria.

3. Marine, Offshore & Coastal Applications

• Use Case: Used for shipboard piping, dock-side loading arms, and seawater intake lines where corrosion and wave-induced movement are constant challenges.
• Borneo Locations: Ports in Sandakan, Kuala Belait, and Muara, as well as offshore platforms. (SS304 Flanges are strongly recommended for these applications.)

4. Commercial HVAC Systems

• Use Case: Isolating vibration from large chillers, cooling towers, and pumps in high-rise buildings, hotels, and hospitals.
• Borneo Locations: Major commercial developments in Bandar Seri Begawan, Kota Kinabalu, and Kuching.
