Method for the capacitive detection of flaws in polymer tubes, and device |
摘要 |
A method for detecting flaws in polymer tubes, especially tubes made of crosslinked polyethylene. The tube that is to be tested is exposed to the electric field of a capacitive triple electrode in a housing including a central housing part and housing flanges. The respective flaw generates test signals which are used for marking or eliminating the flaw.
