Galvanized Rubber Joint Flanges

Galvanized Rubber Joint with Flanges is engineered for industrial applications requiring vibration absorption, noise reduction, and flexibility in piping systems. Manufactured using high-grade EPDM or NBR rubber, the joint is externally coated or clamped with hot-dip galvanized steel flanges, ensuring superior corrosion resistance, especially in outdoor and marine environments.

These expansion joints are ideal for use in HVAC systems, water treatment plants, power generation facilities, and fire-fighting pipelines, where they accommodate thermal expansion, lateral movement, and angular misalignment between pipes. The dual-flange construction provides a secure, leak-proof connection while simplifying installation and replacement.

The galvanized steel flanges conform to ANSI, DIN, or JIS standards and are available in various pressure ratings such as PN10, PN16, or 150LB, depending on project specifications. Internally, the rubber body is reinforced with nylon fabric and steel rings for enhanced tensile strength and longevity under pressure.

All joints are tested according to ISO 4633 and BS EN 681-1 to ensure quality performance under varying temperatures and pressures. Optional third-party inspection and 3.1 MTCs are available upon request for project compliance.

The flanges are made from hot-dip galvanized carbon steel, offering excellent corrosion resistance and mechanical stability. This makes them highly suitable for water distribution, HVAC systems, desalination plants, fire protection networks, and various industrial fluid-handling applications.

Each joint is constructed with precision to allow for axial compression/elongation, lateral deflection, and angular movement, helping protect equipment from stress caused by misalignment, vibration, or pressure surges. The rubber body resists wear, ozone, and aging, while the galvanized flanges conform to international standards such as ANSI B16.5, DIN 2501, or JIS 10K, making them compatible with global project requirements. click here pipes

These joints are commonly used in pipeline systems to:

• Absorb pump and valve-induced vibrations

• Prevent water hammer

• Compensate for minor alignment errors

• Allow easy installation in tight or uneven systems

We offer a wide range of sizes from 1” to 24” and pressure ratings up to PN16 / 150LB. All units undergo rigorous testing as per ISO 4633, BS EN 681-1, and other applicable standards. Full traceability, EN 10204 3.1 MTC, and third-party inspection can be provided upon request. Click for valves
