Gas piping airtight inspection device, gas pipe airtight inspection system and program

摘要

The accuracy of air tightness inspection can be improved as compared with the case where gas tightness test is conducted without considering the volume by piping.In the control section 40 of the gas piping airtightness inspection apparatus 4, when the acquisition section 411 pressurizes the gas piping by pressurizing the gas piping by the supply of fluid, and when the gas pipe is tightly inspected, during the predetermined inspection time period from the start of pressurization A pressure value of a sensor for detecting a pressure value per unit time is obtained.Further, the determining portion (413, 414, 417) is a pressure change of at least a portion of the pressure change characteristic based on a pressure change characteristic determined by a plurality of pressure values acquired; The suitability of the inspection result is determined in accordance with the inspection conditions for determining the suitability of the inspection results showing a predetermined pressure change.Diagram
