Key Features
Single axial movement capability allows the joint to compress and extend along the pipe axis, effectively absorbing thermal expansion, contraction, and installation tolerances. The flange connection design conforms to PN10 and PN16 pressure ratings, ensuring compatibility with standard European pipeline systems. Available in EPDM, NBR, and Hypalon rubber materials, the connector can be tailored to specific media and environmental conditions. The reinforced rubber body with integrated fabric or steel wire reinforcement provides excellent pressure resistance and dimensional stability. The smooth inner bore minimizes flow resistance and prevents sediment accumulation.
Material Options
EPDM (Ethylene Propylene Diene Monomer) offers outstanding resistance to aging, ozone, weathering, and UV exposure. It is ideal for hot water, steam, and outdoor applications, with excellent temperature tolerance from -40°C to 120°C. EPDM is suitable for HVAC systems, cooling water lines, and potable water applications.
NBR (Nitrile Butadiene Rubber) provides superior resistance to oils, fuels, lubricants, and hydrocarbon-based media. It is the preferred choice for petroleum-related pipelines, oil-laden wastewater, and industrial processes involving grease and hydraulic fluids. NBR operates effectively within a temperature range of -20°C to 100°C.
Hypalon (Chlorosulfonated Polyethylene) delivers exceptional resistance to chemicals, acids, alkalis, and oxidizing agents. It also offers excellent weather resistance and flame retardancy. Hypalon is well-suited for chemical processing plants, wastewater treatment facilities, and aggressive industrial environments, with a temperature range of -20°C to 100°C.
Technical Specifications
The connector is available in nominal diameters ranging from DN25 to DN1200 or larger upon request. Pressure ratings include PN10 and PN16 to meet different system requirements. The flange drilling standard can be customized to DIN, ANSI, BS, JIS, or other international standards. Axial compression and extension allowances vary by size, typically ranging from 10mm to 40mm depending on the nominal diameter. The rubber body is reinforced with high-tensile synthetic fabric or steel wire cord to withstand operating pressures and maintain structural integrity. The flanges are constructed from carbon steel, stainless steel, or ductile iron with anti-corrosion coatings as needed.
Applications
This rubber expansion joint connector is widely used in water supply and drainage systems, HVAC and cooling water circulation, chemical processing pipelines, oil and fuel transfer lines, wastewater treatment plants, marine and offshore piping systems, power generation facilities, and general industrial piping where vibration isolation and axial compensation are required.
Installation and Maintenance
The connector should be installed with proper alignment to avoid unnecessary angular or lateral displacement beyond the design limits. Flange bolts should be tightened evenly in a diagonal sequence to ensure uniform gasket compression. The joint requires no routine maintenance but should be inspected periodically for signs of rubber degradation, cracking, or leakage. When replacing, ensure the new connector matches the original specifications for material, pressure rating, and dimensions.
Quality Assurance
Each unit undergoes rigorous hydrostatic testing and dimensional inspection before shipment. Material certificates and pressure test reports are available upon request. The product is manufactured under a certified quality management system to ensure consistent performance and reliability.
