펌프장과 급수 배관용 단구형 고무 익스팬션 조인트

It can be considered, but the minimum pressure, vacuum condition and resistance to inward collapse must be confirmed. A joint selected only for positive-pressure service should not automatically be used on the suction side.

No. A rubber joint provides flexibility and vibration isolation but is not a stand-alone water-hammer protection device. Surge risks require appropriate valve control, pressure-management equipment, air management and system design.

Not always. Their need depends on working pressure, axial thrust, pipe anchors, allowable equipment loads, expected movement and pullout risk.

No. Pipes, valves and equipment must be supported independently by suitable supports, hangers or foundations. A rubber expansion joint should not be used as a load-bearing component.

The elastomer should be selected according to the operating medium, concentration, temperature, environment and project requirements. Water, oil, chemicals and mixed industrial fluids may require different rubber compounds.

Please provide the nominal size, medium, temperature, pressure, possible vacuum, flange standard, installation length, movement, restraint requirement, material requirements, quantity and project drawings.
