Rubber slip on sleeve type rubber expansion joint Display video
Products Description
Rubber slip-on sleeve type rubber expansion joint (REJ) is
designed with lower spring rates for reduced reaction
forces and greater movement capabilities within a compact body.
This optimally designed slip-on and lightweight construction represents the most cost-effective arrangement for low pressure applications. Mating flanges and hardware are not required, adding to the cost-effectiveness of this arrangement.
Additionally, it is designed to absorb large all-directional movements,reduce noise and vibration, have a cycle life in the tens of millions, compensate for misalignments, provide access to ducting and equipment, and relieve duct and anchor stresses.
This slip-on sleeve type REJ is designed with minimal
reinforcement for ducting applications operating within ± 5 PSIG(0.3bar)
By using this type of expansion joint, the connection between pipelines can achieve elastic expansion, contraction, and deformation, avoiding safety issues such as rupture and water leakage during pipeline operation. This type of rubber expansion joint also plays a good role in reducing pipeline noise and preventing vibration transmission. Traditional metal expansion joints have problems such as high cost, high noise, and difficult maintenance, while the advantages of rubber expansion joints have been widely recognized.

advantage
Virtually eliminates sediment buildup：The product is designed to virtually eliminate sediment buildup, which ensures that the system operates optimally.
Easy to install：The sliding sleeve design eliminates the need for paired flanges and hardware, making it an economical solution. This means that organizations can save costs that were originally used for additional hardware and maintenance.
Extremely lightweight and flexible：Expansion joints are very lightweight and flexible, making them easy to install. Its flexibility enables the system to adapt to changes in temperature, pressure, and motion. It also compensates for minor misalignment and offset, providing additional flexibility for the system.
Absorbs noise, vibration and shock：One of the most significant advantages of a sliding expansion joint is its ability to absorb noise, vibration, and impact. This feature is beneficial for applications where noise reduction is crucial, such as in power plants. Expansion joints ensure that the noise generated by the system is minimized.
The sliding sleeve expansion joint is equipped with a variety of tube and cover elastomers, including EPDM rubber, chloroprene rubber, and nitrile. This ensures the universality of the product and its applicability to different applications.
