常见问题

?What is the difference between a rubber joint and a rubber expansion joint?

The terms are often used to describe similar flexible rubber pipeline connectors. However, the actual sphere design, connection type, materials, movement capability and operating conditions may differ, so the approved drawing and technical specification should be checked.

?What movements can a rubber expansion joint accommodate?

Depending on its design, a rubber expansion joint may accommodate limited axial compression, axial extension, lateral movement and angular deflection. Combined movement capabilities should be confirmed against the specific product data.

?Can a rubber expansion joint support pipe or valve weight?

No. Pipes, valves, pumps 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.

?Are control rods required for every rubber expansion joint?

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

?How should the elastomer material be selected?

The elastomer should be selected according to the operating medium, concentration, temperature, installation environment and project requirements. Material names alone do not replace a compatibility review.\n\nFAQ 6\n\nQuestion:\nWhat information is required for a quotation?\n\nAnswer:\nPlease provide the nominal size, medium, temperature, operating and design pressure, possible vacuum, connection type, flange standard, installation length, movement requirements, restraint conditions, material requirements, quantity and project drawings.

?询价橡胶接头需要提供哪些资料?

建议提供公称直径、介质、工作温度、工作压力、可能的负压、连接方式、法兰标准、安装长度、位移要求、限位条件、材料要求、采购数量及项目图纸。
