Single Sphere Expansion Joints Fabric

 

1. Single Sphere Expansion Joints Fabric Introduction: 
1). This product can greatly reduce pipeline system shock and noise. And can fundamentally resolve pipe joints displacement, axial stretch and non-concentricity.


2). By using different materials, it can be made many kinds to cater for different medium and environment. Such as acid resistance, alkali resistance, corrosion resistance, oil resistance and heat resistance etc.

 

3). The material is pure rubber, sealing is very good. It is in light weight, very easy for installation . This product has long life performance, but must be not contact with sharp metal instruments to avoid piercing the sphere. 

 

4). The product can be used for lift and transportation of raw water and sewage, transportation of water supply cooling cycle water thermal power ,condensate water of metallurgy industry and chemical industry

3. Single Sphere Expansion Joints Fabric 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 271 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.

Note:

1.Flexible Rubber joints supply range can be up to DN3000, detailed data can be offered upon request.
2. Control units must be used when piping is not properly anchored.
3. The rated pressure 2.5MPa products will only be sold with control units.
4. Flexible Rubber joints pressure rating is based on 30°C operating temperature. The pressure rating is reduced at higher temperatures.
5. Flexible Rubber joints weights in the above table are joints with DIN PN16 drilling retaining ring flanges.
6. Movements shown in the above table are non-concurrent.
7. Rated pressure in the above table is the maximum "working pressure". Test pressure is 1.5 times "working pressure", Burst pressure is 4 times " work pressure".
8. Normally, the flange drilling is based on DIN PN16, ANSI 150/250/300 lbs, BS PN10, JIS 10K are also available upon request.
