Single Sphere EPDM NBR CR Expand Joint Flange Type Expansion Compensators
Single Sphere EPDM NBR CR Expand Joint Flange Type Expansion Compensators
Product Description
Single Sphere EPDM NBR CR Expand Joint Flange Type Expansion Compensators are designed to provide excellent flexibility, vibration absorption, and movement compensation in various industrial piping systems. The single sphere structure offers superior elasticity and effectively absorbs thermal expansion, axial compression, lateral displacement, and angular deflection, helping protect pumps, valves, and pipelines from mechanical stress and vibration damage. Manufactured with high-quality EPDM, NBR, or CR rubber materials, these expansion compensators can be selected according to different working environments and media conditions. EPDM is ideal for hot water, steam, and chemical resistance applications; NBR provides outstanding resistance to oils and petroleum-based media; while CR (Neoprene) offers excellent weather, ozone, seawater, and abrasion resistance. The flange type connection ensures easy installation and compatibility with international standards such as ANSI, DIN, JIS, and BS. Widely used in water treatment systems, HVAC projects, chemical plants, marine engineering, power stations, and industrial pipelines, these flexible expansion compensators deliver reliable sealing performance, durability, and long-term operational stability under demanding working conditions.
Performance characteristics
