Key Features
Floating Flange Design: Both ends feature loose, rotating flanges that allow 360° rotation. This eliminates bolt-hole alignment struggles, significantly reducing installation time and labor costs.
Wide Size Range: Available in nominal bore sizes from DN100 to DN150, accommodating standard pipeline specifications.
High Elasticity & Flexibility: The natural or synthetic rubber body provides exceptional flexibility, effectively dampening mechanical vibrations and absorbing pipe movements (axial, lateral, and angular).
Durable Construction: Reinforced with multiple layers of high-strength nylon cord fabric and a sturdy inner steel wire ring, ensuring high pressure resistance and structural integrity under demanding conditions.
Corrosion & Abrasion Resistance: The inner rubber layer offers excellent resistance to water, seawater, weak acids, alkalis, and abrasive particulate media, extending service life.
Temperature & Pressure Range: Suitable for operating temperatures from -10°C to +115°C (depending on rubber grade) and working pressures up to 1.6 MPa (16 bar), with higher pressure ratings available upon request.
Technical Specifications (DN100-DN150)
Nominal Diameter: DN100 (4") / DN125 (5") / DN150 (6")
Connection Type: Loose floating flanges (drilled to PN10, PN16, or ANSI 150 standards).
Flange Material: Carbon steel (electro-galvanized or painted) or stainless steel (optional).
Rubber Material: EPDM, NBR, Neoprene, or Natural Rubber (selected based on media compatibility).
Working Pressure: 1.0 MPa – 1.6 MPa (standard); customizable for vacuum or higher pressure.
Axial Extension/Compression: ±25mm to ±40mm (size-dependent).
Lateral Deflection: ±15mm to ±25mm.
Angular Deflection: 15° to 25°.
Installation Advantages
No Pipe Threading Required: The floating flanges rotate freely, allowing easy bolt insertion even when pipe flanges are misaligned.
Maintenance-Friendly: Serves as a removable spool piece, simplifying system maintenance and component replacement without cutting pipes.
Space-Efficient: Compact body length reduces space requirements compared to metal expansion joints.
Typical Applications
HVAC chilled water and hot water systems
Pump suction and discharge connections
Cooling towers and water treatment plants
Fire protection systems
Marine and shipbuilding pipelines
Chemical, food processing, and pharmaceutical fluid transfer
