DN2000-400MM Round Fabric Bellow Expansion Joint Structure of Fabric Layers
The number of layers or plies is dependent upon the design conditions and we usually limit fabric bellows expansion joints to five or more layers.
1st ------ 0.15mm stainless steel wire mesh (outer layer)
2nd ------1.2mm silicone fabric
3rd ------ 0.9mm*2ply thickness glass fiber
4rd ------ 0.12mm thickness PTFE cloth
5th------0.9mm*2ply thickness glass fiber
