Chemical resistance made of high quality semi-finished products
Because of thegreat mechanical demands which may be required in individual cases, and the chemical resistance necessary, PTFE bellows are manufactured from special high-grade semi-finished products with total impermeability.
The shape of bellows depends on the intendedapplication and is based on the operating pressure, operating temperature, requiredelongationand radial misalignment.
The followingbellowtypeshaveprovensuitable in practice:
prickpointed, type S:
cuttinground, type R:
cutting angular, type E:
Please provide the following technical information when enquiring:
1. Installation length
2. Elongation, +/-
3. Misalignment, parallel and angular
4. Medium
5. Operating pressure
6. Operating temperature
In many cases, these aling conefrom a corresponding PTFE composition is sinteredon to bellows for fittings without stuffing boxes.
