Leak inspection<br />
• Bubble method<br />
The essential matter of the method is as follows:<br />
Registration of local leakages in an under-test item by appearing of indicator gas bubbles in indicator liquid<br />
(indicator cover). The method is used for <strong>testing</strong> the impermeability of reservoirs welded joint, fluid power and<br />
gas systems under the overpressure,(which can be created by vacuum pump).<br />
Foam-film indicator(Proof Check) is applied on the under-test joint weld and overpressure is generated. Air<br />
(check gas), penetrating through the joint weld microflaws, impacts mechanically on foam-film indicator,<br />
accumulating on the defective place, deforms it. In this case bubbles or foam swelling can be seen .<br />
