This standard specifies the differential pressure test (hereinafter referred to as the test) method for confirming the airtightness of titanium welded pipes (hereinafter referred to as the welded pipe). Remarks: The differential pressure test method refers to the air pressure difference that occurs between the A system and B system shown in Figure 1 [hereinafter referred to as differential pressure]. ) to test for the presence or absence of leakage from welded pipes.
