Is the fresh water line of your installation above ground or buried? All the fresh water in our facility is on the ground; the weather is extremely cold in the north during winter, and dealing with freezing issues is a real headache!
The fresh water for our facility comes from underground
Generally, fresh water is on the ground! The circulating water and fire-fighting water are buried! This post was last edited by chengkang on 2009-4-13 22:01]
The fresh water in our installation, as I can see, is above ground, not buried. I think it should be fine; I’m not sure if there are any special requirements regarding the design
The fresh water lines of facilities located in the north take winter freezing into account, and they are usually buried underground before entering the facility.
The fresh water for the public systems within our plant facility comes from buried pipes; it reaches the boundary of the production units, where it then runs above ground on each unit. For anti-freezing measures, our general approach is as follows: in winter, for systems that require little fresh water, we close the main valve at the system boundary and drain the fluid through the flanges; the system is then cleaned with air, and demineralized water is used in place of fresh water (mainly for mixing purposes, in small quantities) ； If a large amount is used, more inspections are necessary to minimize the occurrence of freezing.
Primarily for anti-freezing purposes, in refineries located in the north, the water pipelines are buried deep beneath the permafrost layer, whereas in refineries in the south, where the lowest winter temperatures remain above zero degrees, it is possible to install the pipelines overhead.
Our plant is in the south, where the fresh water pipelines are underground; corrosion of these pipelines is severe, leading to frequent leaks that need to be dealt with. It seems that the fresh water pipelines in refineries in the south should be installed above ground.
Yes, our main water supply is underground, but the fresh water used in various facilities is supplied through overhead pipelines. In winter, to prevent condensation and freezing, we have to release this water, which is really a waste
Here, all the main pipelines are underground. In the past, the cooling water pipelines for pumps were also underground, but over time it became difficult to address leaks, so the pipelines inside the equipment were moved onto pipe racks; during winter, continuous flow of water is used at the terminals to prevent freezing.
Fresh water pipelines are all buried underground, but corrosion protection poses a challenge.
Our company’s utility systems consist of underground water pipelines, which become above ground once they enter the facility.
In the north, it is better to bury fresh water underground, and the valves should be placed in valve chambers to prevent them from freezing. Generally, the valves for fresh water and fire water in southern designs are located on the ground, making them extremely prone to freezing. Additionally, in the north, the backflow valve for pipelines must be installed above the backflow pipe, also for anti-freezing purposes.
In our fresh water supply system, the main pipeline runs underground, while some branches are above ground. The branches that are used frequently in winter have end fixtures with continuous water flow to prevent freezing; those branches that are not used often in winter have valves located in underground valve chambers, which are closed when not in use and opened when needed.
The main fresh water supply line of our installation is buried underground, while the branch lines are above ground. For those branches that are used frequently in winter, a continuous flow of water at the end is used to prevent freezing; for those branches that are not used often in winter, the valves are closed to drain the water from the end, and the valves are opened when they need to be used. :handshake
We also bury them underground, which is quite troublesome; personally, I think it’s better to use pipe racks
In cold regions, fresh water lines should be buried below the permafrost layer.
We, the North. Fresh water, circulating water, and fire-fighting water are all buried underground. In some areas, the structures are on stilts due to severe underground corrosion, but this is very rare. For anti-freezing and condensation prevention, I usually use insulation.
When the facility was built, it was buried underground; later, some parts of it were constructed above ground. Due to poor corrosion protection, there were multiple instances of perforations. The insulation around the service points above ground is of good quality, so they are sealed off in winter.

Before entering the device, it is buried underground; once inside the device, it is installed above ground. In winter, some water always has to be drained.
