According to Article 14.1.5 of the GB 50074-2002 Code for Design of Oil Depots, the power distribution cables in the main production areas of oil depots should be copper-core cables, and it is advisable to lay them by direct burial or in cable trenches filled with sand. Cables within the tank area must be laid underground in accordance with the specifications. Must the fire sprinkler pipes in the tank area be installed underground?
The cable he mentioned. Can the spray pipeline be placed in a pipe tray?
The spray pipelines should be laid underground; it’s not suitable to run them in ducts, as they can be damaged by heat in the event of a fire
Why are all the ones here ductwork?:D
There is no fixed requirement regarding whether the fire sprinkler pipes in the tank area should be buried or laid in ducts. The advantage of burying them is that it saves space and provides better insulation, reducing the risk of freezing. However, the downside is that maintenance is more difficult, and proper anti-corrosion measures are necessary; otherwise, leaks are likely to occur. The advantages of laying ducts are their simplicity and ease of maintenance; the disadvantages, of course, are the large amount of space they occupy. In the north, where temperatures are low, freezing can occur easily, so proper insulation is necessary. It is up to each factory to decide based on its own needs
Does the x fire pipeline still need maintenance? No need; it is usually buried directly inside the fire dike
Inspection is definitely necessary; Chapter 14 of the GB50974-2014 Technical Code for Fire Water Supply and Fire Hydrants is dedicated to maintenance and management. Not to mention anything else, the annual system interlock test is essential
