Flexible Stainless Steel Metal Expansion Bellows

1.Specifications

 metal bellows 
1)Stainless steel or copper 
2)High flexibility 
3)High&low

2.Discription

Universal type expansion joint is a joint capable of absorbing not only displacementin the axial movement, but also displacement in the lateral deflection. The number of corrugation of two bellows determines displacement in the axial movement and angular rotation of two bellows and length of the intermediate pipe determines displacement in the lateral deflection. This joint can absorb displacement in the lateral deflection in 360 direction. in case of pipe without displacement in the axial movement, as internal pressure thrust is restricted by the tie rod does not act on the anchor.

3.Features

1)Shock absorption
2)Easy installment and keep up
3)Resistant to medium and temperature, pressure
4)This product can greatly reduce vibration and noise, pipeline system but can not solve all kinds of pipe interface displacement, degree of axial stretching problems.
5)The material can be made according to different acid, alkali, corrosion, oil heat and other kinds of species to adapt to various of media and the environment.
6)Material is a polar rubber, sealing, light weight, easy installation and maintenance, long life, but to avoid contact with sharp metal instruments, so as not to puncture the sphere.
7)Without supporting bracket should use flexible stent, installation bolt tightened to use the diagonal method
Such as the pipeline pressure is too high, the application of limit bolts to both ends of the flange together.
Flange connection standard adapt GB standard as to other standards, can be explain. Level of the product working pressure 0.1-6.0Mpa. 

4.Advantages:

1)Reduce vibration
2)Dampen sound transmission
3)Compensate lateral, torsional & angular movements
4)Compensate axial movements
5)Minimal face-to-face dimensions
6)Lightweight
7)Low movement forces required
8)Reduced fatigue factor
9)Reduced heat loss
10)Corrosion, erosion resistant
11)No gaskets
12)Easy cleaning and maintenance

 
5.Structures:

 1). Bellows+Outside braid+Interlock liner+Collars
 
2). Outside braid,middle double bellows,lined with inside braid and lined with inside interlock or nothing inside;
 
3). Main material: Bellows:Stainless steel 304/316 and so on(thickless:0.25-0.30mm)

 
6.An Overview of Liwei Factory:

We have more than 25 years' experience of manufacturing. We import high quality rubber from Japan and USA as raw materials of the expansion joints. Moreover, we have the largest vulcanizing boiler(5m*15m) in Asian.
