Roles of Rrubber Expansion Joints in Our Daily Life-Product knowledge

Rubber expansion joints are a critical part in any pump piping system as they provide the flexibility necessary to absorb system dynamics associated with vibration and temperature and pressure changes within piping. Careful selection of expansion joint design and material for a given application, as well as properly engineered installation, are important factors for determining performance. When designed, applied and installed properly, it is not unusual to achieve useful service life for 15 to 20 years in most industrial applications.

Unlike metal expansion joints, the majority of failures related to rubber expansion joints are not catastrophic in nature. During routine inspections, signs of fatigue and/or premature failure can be easily detected in rubber expansion joints, long before the actual failure occurs.

As a main accessory for long-distance transit pipeline, the rubber expansion joint is inevitable ageing and corroding. Therefore, the maintenance is important when using rubber expansion joint. Even though we do not use rubber expansion joint, it will wear out with the time. When preserve the joints, we should put them under cool and dry environment, and let them far away from strong acid, strong alkaline and heat source. Except natural ageing, if we pay attention to the proper maintenance of expansion joints, their service life will effectively increase.
