Are there any regulations stating that pipelines for flammable and explosive substances should not be installed adjacent to water pipes, air pipes, etc., in the same pipeline tray?

Relevant regulations require that pipelines carrying flammable and explosive materials should be installed separately from those carrying non-flammable and non-explosive materials, avoiding placement adjacent to each other on the same floor, in order to reduce the risk of accidents. The specific requirements will vary according to the relevant standards and regulations of **and the region. In some cases, if they are arranged in upper and lower layers, corresponding safety measures also need to be taken to ensure isolation and protection. When designing and arranging pipelines, specific industry standards and safety regulations should be followed. .

There seems to be no requirement in this regard. For specific details, refer to the standard \"Code for Design of Layout of Metal Piping in Petrochemical Industries\" SH3012-2011

Chapter 7 of the “Fire Protection Code for Petrochemical Enterprises” specifies the requirements

I encountered a similar problem years ago; the overall layout was determined before construction began. Gas pipes are on the top floor, acid and alkali pipes are on the bottom floor, while water pipes and compressed air pipes are in the middle, with specified spacing requirements. I haven’t checked the specific standards.

In chemical process design, there are indeed relevant regulations regarding the layout of pipelines for flammable and explosive media alongside other types of pipelines. In accordance with standards such as the \"Code for Fire Protection Design of Petrochemical Enterprises\" (GB 50160), there are certain principles regarding the layout of pipelines carrying flammable and explosive materials alongside pipelines carrying non-hazardous or low-hazard materials such as water or air. Within the same pipeline tray, it is necessary to avoid placing pipelines carrying flammable and explosive materials directly next to those carrying non-hazardous materials, in order to reduce the risk of mutual interference in case of a leak, as well as the risk of fire and explosion. If adjacent placement is necessary, sufficient safety distances must be maintained, and appropriate isolation measures should be taken. Pipelines carrying flammable and explosive media can be installed in upper and lower pipe trays alongside pipelines carrying non-hazardous media, but it is still necessary to maintain an appropriate vertical distance to prevent liquid leaks from the upper pipelines from falling onto the flammable and explosive media pipelines below and causing accidents. Within the same pipe rack or ductwork, various types of pipes should be divided into zones based on their level of hazard, and fire separation measures should be implemented. Factors such as emergency shutdown and pressure relief also need to be taken into account to ensure that risks can be controlled promptly in case of abnormalities. Therefore, it is not absolutely impossible to install pipelines for flammable and explosive media in the same pipeline tray as water pipes, air pipes, etc.; the key is to strictly adhere to relevant design codes and standards to ensure that all necessary safety measures are properly implemented. It is generally permissible to arrange upper and lower layers as long as the code requirements are met, but careful design is still required to ensure safety
