For pressure vessels that fall outside the category permitted to have no inspection holes, but for which it is not possible to install such holes due to special circumstances, what requirements are set forth in the \"Regulations on Safety Supervision of Pressure Vessels\"? ........................................................................... Answer: (Reference) The following requirements must be met simultaneously: (1) 100% non-destructive testing of each weld. (2) The calculated thickness shall be indicated on the design drawings, and thickness measurements should be carried out regularly during the vessel’s service life or during inspections. (3) The inspection interval should be reduced accordingly
1. Perform 100% non-destructive testing on each longitudinal and circumferential weld; 2. The calculated thickness shall be indicated on the design drawings, and thickness measurements should be carried out regularly during the service of the pressure vessel or during inspections ; 3. Correspondingly shorten the inspection cycle ;
⑴ 100% non-destructive testing (radiographic or ultrasonic) is performed on each longitudinal and circumferential weld. ⑵ The calculated thickness shall be indicated on the design drawings, and thickness measurements should be carried out regularly during the service of the pressure vessel or during inspections; ⑶ the inspection interval shall be correspondingly shortened.
1. Calculated thickness indicated on the drawings 2. 100% non-destructive testing 3. Regular thickness measurement
The design unit shall propose specific technical measures, such as increasing the number or proportion of inspection items during manufacturing, and specify the key inspection items and methods for regular inspections during the equipment’s operation.
This question is quite old and does not comply with the current provisions of the Code for Solid and Liquid Storage. It is recommended that the moderator make changes.
Increase the proportion of non-destructive testing of welds to 100%; it should be specified whether thickness testing should be given priority during the inspection of pressure vessels or what the inspection interval should be
(1) 100% non-destructive testing shall be conducted on each weld. (2) The calculated thickness shall be indicated on the design drawings, and thickness measurements should be carried out regularly during the vessel’s service life or during inspections. (3) The inspection interval shall be reduced accordingly
Requirements are put forward for regular inspections of the equipment during use
The following requirements must be met simultaneously: (1) 100% non-destructive testing shall be conducted on each weld. (2) The calculated thickness shall be indicated on the design drawings, and thickness measurements shall be carried out regularly during the vessel’s service life or during inspections. (3) The inspection interval shall be reduced accordingly (Article 47 of the Pressure Vessels Regulations)
