Issues with the installation of gas pipelines within the factory premises?
Thread Content
Can the gas pipelines within the factory area be buried? Which standards should be referred to for the design and construction requirements of buried installations? Thank you
Check out the standards GB 50251 \"Code for Design of Gas Pipeline Engineering\", GB 50369 \"Code for Construction and Acceptance of Long-Distance Oil and Gas Pipelines\", and GB/T 21448 \"Technical Code for Cathodic Protection of Buried Steel Pipelines\", and then look into other standards as well. Additionally, the pipelines within your factory area may also need to comply with the standards for urban gas pipelines.
No problem; our company is converting its coal boilers to natural gas, and the pipelines will be buried underground
The primary standard for selection is GB/T 50183, with GB 50251 and GB 50369 serving as supplementary standards
Of course it can be buried. Off-site areas are classified as long-distance pipelines, while industrial pipelines of type GC are considered for installation on-site. Comply with GB/T50183, GB/T50160, GB/T50016, etc.
It is best to lay it overhead inside the factory; there is no problem with long-distance transmission
The plant area can be buried; everything specified in the guidelines applies. It is also possible to combine burial with an elevated design
In general, pipelines in factories are installed on pipe racks or pipe tunnels. When buried, the pipes are prone to corrosion; moreover, repairs become difficult in case of leaks. From a safety perspective, if the pipes are accidentally damaged during construction, it could lead to serious problems, so it is safer to install them above ground
