The most professional single sphere flexible rubber expansion joint:

1. Rubber Joint reasonable structure; High flexibility
2. Rubber: EPDM NBR NR CR IIR
3. Pressure: 0, 6-1.6MPa
4. Good quanlity&cheap

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

The Style 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
