Does it fall under pressure pipelines? Is it subject to **regulation**, and which standards should be applied?

To answer this question, it is necessary to know the specific type of pipeline and the industry in which it is used. If it is a pressure pipeline, it usually needs to comply with relevant standards, such as the \"Regulations on Safety Inspection of Boilers and Pressure Vessels\" and the \"Technical Specifications for Urban Gas Pipeline Engineering\", among others. At the same time, under normal circumstances, pressure pipelines fall within the scope of regulation and must comply with relevant regulatory laws and standards. For specific details, you can consult the relevant departments or professional institutions for confirmation. .

According to the Catalogue of Special Equipment. Pressure pipelines refer to tubular devices that use a certain pressure to transport gases or liquids. They are defined as pipelines with a maximum operating pressure of 0.1 MPa (gauge pressure) or more, carrying gases, liquefied gases, steam, or liquids that are flammable, explosive, toxic, corrosive, and have a maximum operating temperature equal to or higher than their standard boiling point, and with a nominal diameter of 50 mm or more. Except for pipes with a nominal diameter of less than 150 mm and a maximum operating pressure of less than 1.6 MPa (gauge pressure), as well as the pipes that form part of the equipment used for transporting non-toxic, non-flammable, and non-corrosive gases. Among them, the safety supervision and management of oil and gas pipelines shall also be carried out in accordance with laws and regulations such as the Work Safety Law and the Oil and Gas Pipeline Protection Law.
