TUBING, FILMS, TILES
Cleaning and reuse of tubing
In general, cleaned fluoroplastic tubing should only be reused if the transported product is known and rated with “+” in the chemical resistance chart (page 347).
It is not recommended to reuse the tubing with unknown products and mixtures of chemicals. For all water-soluble substances (e.g. salts, acids, bases etc) you can use water as cleaning agent.
Volatile solvents such as alcohols, esters, ketones, low-boiling hydrocarbons, chlorinated hydrocarbons are given off reversibly by storing under aeration (only if they have not been absorbed by the interior surface of the tubing).
If you are using substances which can only be eliminated by organic solvents or if you are using toxic and dangerous products, the tubing should be disposed appropriately after use. A visual inspection or,
in case of unclarity an inspection according to EN 12115, has to be made before reusing cleaned tubing.

We would be glad to send you a quotation. For quick proces-

Do you need special tolerances for outer or inner diameter (e.g. Ø 10 mm +/- 0,1 mm; this means tubing can vary between 9,9 mm and 10,1 mm)?
Shall the tubing be deformable, for example for making flanges? Up to which temperature will the tubing be used?
Which pressure shall the tubing resist?
Shall the tubing be electroconductive? Shallthetubingbetransparent?
Shall the tubing have a special surface quality?
Do you need certificates? (e.g. test certificates, certificates of compliance or FDA certificates)
