Pipeline flange installation information construction method

The invention discloses a pipeline flange installation information construction method, which adopts a management system with a built-in database for management, sets gasket and bolt data in the database, and comprises the following steps: firstly, acquiring a single-line diagram with a flange number and flange related information for pipeline construction, and storing the single-line diagram andthe flange related information in the database; calculating the fastening torque of a single bolt of each flange by the system, and obtaining the bolt and the gasket required by the connecting flangeand the corresponding bolt fastening torque from the database according to the flange number; after the flange is installed, inputting the installation information into the database; and after the pressure test is finished, generating airtight test data by the pipeline system with airtight test conditions to prepare an airtight test; the management system also comprises a system, which is developed based on the real-time d
