A. W. Schultze PTFE-bellows
Chemical resistance made of high quality semi-finished products
PTFE-Bellows
Because of the great 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 intended application and is based on the operating pressure, operating temperature, required elongation and radial misalignment.
Forms of PTFE Bellows
The following bellow types have proven suitable in practice:
prickpointed, type S:
- mostelongation
- low pressures
cuttinground, type R:
- moderate elongation,
- medium pressures
cutting angular, type E:
- least elongation
- high pressures
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 cone from a corresponding PTFE composition is sintered on to bellows for fittings without stuffing boxes.
