How to check the internal pressure resistance of quartz glass tubes?
This specification regulates the sample, instrument, process and achievement identification of the internal pressure resistance inspection of quartz glass tube. This specification applies to the internal pressure resistance inspection of quartz glass tubes.
Internal pressure resistance: the hydraulic pressure received in the quartz glass tube.
Rising speed: the added value of pressure per unit time.
Test principle
Hydraulic pressure is applied to the quartz glass tube, and the internal pressure resistance of the quartz glass tube is obtained according to the value of the applied hydraulic pressure.
Sample requirements
The outer diameter of the sample to be tested is not more than 30mm, and the length is not more than 1000mm.
The two ends of the quartz glass tube to be tested should be free of cracks and avalanches, and the end face of the tube and the tube axis should be straight.
