May Class A liquids such as methanol, as well as flammable gases and Class A strong oxidizers, be conveyed through gutters? Are there any regulations that explicitly prohibit using ducts in trenches? Can they be placed in trenches together with other pipes (that are not of Category A)? ? ? If it’s not possible to walk, is it necessary to use the pipe rack instead? . . . . ? What are the layout principles for such pipelines? ? Thank you!
You don’t need to worry about these issues; the design institute will follow strict standards in carrying out the work.
May I ask why it’s not allowed, and which provision does this refer to? ? Thank you!
;P aren’t things like this difficult to monitor when they end up in sewers?
Try to install the piping at a high level; for pipelines carrying flammable liquids or gases that must run underground, measures should be in place to prevent accumulation
The poster can refer to page P463 of \"Design of Pressure Pipelines and Engineering Examples\" (2nd edition); the layout of pipes in trenches must meet the following conditions: 1. The medium transported is non-corrosive, non-toxic, and not flammable or explosive. Class A liquids are not suitable for laying in pipe trenches.
It is not recommended, but it’s not forbidden just because it’s not mandatory; safety concerns are the main factor, such as the leakage and explosion incidents of buried pipes in Qingdao
