There are normally no tooling costs so that small quantities can also be favourably quoted and quickly delivered.
For difficult and demanding applications with regard to operation and safety, Ceetak uses the knowledge and facilities in its Bietighiem development department.
Finite element analysis (FEA) enables configuration of the best possible shape, selection of suitable material and advance calculation of the service life.
PTFE is a material that is resistant to nearly 260C.
Applications for diaphragms and bellows in this material include: chemicals, pharmaceuticals and foodstuffs industries; medical engineering; and offshore installations.
PTFE diaphragms control, separate, convey and seal aggressive media in valves and pumps.
But in some causes the user without hesitation decides in favour of this material because, with small quantities, other materials would be expensive on account of tooling costs.
Bellows provide a flexible connection for the compensation of elongation in piping systems.
They also serve as a protection for glass tubes in materials processing plants or for universal joints.
The bellows themselves can be produced in a pliant PTFE and the connecting flange in glass-fibre-reinforced PTFE.
Polar seals offer them with external diameters from 10 to 2000mm and for pressure up to 10bar.
