Single Sphere EPDM NBR CR Expand Joint Flange Type

Single Sphere EPDM NBR CR Expand Joint Flange Type

Product Description

Single Sphere EPDM NBR CR Expand Joint Flange Type is a highly flexible and durable piping component designed to absorb vibration, reduce noise, and compensate for axial, lateral, and angular movements in various pipeline systems. Featuring a single sphere structure, this type of expansion joint provides superior elasticity and movement capability compared to traditional designs, effectively minimizing stress on connected equipment such as pumps and valves. It is manufactured using high-quality rubber materials including EPDM for excellent resistance to heat, ozone, and weathering, NBR for strong oil and fuel resistance, and CR (Neoprene) for balanced mechanical properties and moderate chemical resistance, allowing it to adapt to different working media and environments. Reinforced with multiple layers of high-strength synthetic fabric and optionally internal steel wire or retaining rings, it ensures reliable performance under pressure and long service life. The flanged connection, available in standards such as ANSI, DIN, and JIS, enables easy installation, secure sealing, and convenient maintenance. Widely used in water supply systems, HVAC installations, chemical processing pipelines, and marine applications, this single sphere rubber expansion joint offers a cost-effective, customizable solution that enhances pipeline safety, reduces maintenance costs, and improves overall operational efficiency.
