Due to favourable integrated performance, they can be widely used in chemical industry, construction, water supply, drainage, oil industry, light and heavy industry, refrigeration station, water heating system, fire fighting system, electric power system, etc.
3. Suitable medium:
According to different material, acid resistance rubber joint, flameproof rubber joint, oil resistant rubber joint, thermostatic rubber joint, low temperature resistant rubber joint, wear resistance rubber joint can be made to suitable for various kinds of medium, and environment.
4. Flexible Rubber Joint Features and Benefits:
1. Absorbs Directional Movement
Thermal movements appear in any rigid pipe system due to temperature changes. The Single Sphere Rubber Expansion Joint low profile wide arch allows for axial compression or axial extension, lateral deflection as well as angular and torsional movements. (Note: Rated movements in this publication are based on one plane movements.Multiple movement conditions are based on a multiple movement calculation. Contact Ldflex for information when designing multiple pipe movements.)
2. Less Turbulence or Material Entrapment
Expansion joints are manufactured with the integral rubber flange joining the body at a true 90º angle. This ensures the product will install snug against the mating pipe flange free of voids creating less turbulence in the pipe system. The Single Sphere Rubber Expansion joint also has a self-flushing arch which eliminates media buildup and the need for a filled arch spool joint resulting in greater movement capability and lower spring rates.
3. Absorbs vibration, noise and Shock
The Single Sphere Rubber Expansion Joint joints effectively dampen and insulate downstream piping against the transmission of noise and vibration generated by mechanical equipment. Noise and vibrations caused by equipment can cause stress in pipe, pipe guides, anchors and other equipment downstream. The Single Sphere Rubber Expansion Joints will help relieve noise and vibration occurrences in a pipe system. Water hammer and pumping impulses can also cause strain, stress or shock to a piping system. Install Single Sphere Rubber Expansion Joint to help compensate for these system pressure spikes.
Rubber expansion joints are mainly manufactured by manual wrapping of rubber sheets and fabric reinforced rubber sheets around a bellow-shaped product mandrel. Besides rubber and fabric, reinforced rubber and/or also steel wires or metal rings are added for additional reinforcement. After the entire product is build up on the mandrel, it is covered with a winding of (nylon) peel ply to pressurize all layers together before pressurization.
