Pipeline declaration
Thread Content
I need to know which types of pipelines in the chemical industry are required to undergo inspection and testing. It’s urgent; thank you! The purpose of the application is for the supervision and inspection of pressure pipeline installation/for the project owner to handle the registration procedures for use.

I’m not quite sure what the LZ means – what is the purpose of conducting these tests? Is it the supervision and inspection of pressure pipeline installation, the handling of registration procedures by the project owner for use, or the online inspection of industrial pipelines? 1. In accordance with Article 88 of the Regulations on the Safety Supervision of Special Equipment, pipelines with a maximum working pressure of 0.1 MPa (gauge pressure) or higher for gas, liquefied gas, or steam media, or for liquid media that are flammable, combustible, toxic, corrosive, and have a maximum working temperature equal to or higher than their standard boiling point, and whose nominal diameter is greater than 25 mm, are considered pressure pipelines. 2. The design and installation of pressure pipelines within this range must be carried out with the appropriate qualifications and permits, and the user entity must go through the necessary procedures. For reference!
