Is the buried part of the fire hydrant insulated?

Don't keep warm, do antiseptic.

Need to look at the place.

Building. Firefighting. Design Specifications.

Point 4 stipulates: fire water supply in severe cold and cold areas. Pipeline. And.

Outside. Fire hydrant.

should be taken. Anti-freeze measures.

The buried depth of the outdoor fire pipe can be referred to the water supply pipeline, and the buried depth of the water supply pipeline can be found in the "Outdoor Water Supply Design Code" (GB50013-2006) and the relevant provisions in the description of the provisions: (1) The buried depth of the pipeline in the specification shall be determined according to factors such as freezing conditions, external loads, pipe properties, anti-floating requirements and crossings with other pipelines.

The valve of the outdoor fire hydrant is underground, and the residual water after the valve can be cleaned before winter.

This definition of the north is a bit big, if the Northeast is estimated to need insulation, how to do it depends on the local standard atlas and common practices, you look at the regulations on the national standard atlas.

Generally, it is not needed, and some parts such as the door of the underground garage and the external unloading area will be needed in winter, and of course other measures can also be taken, such as electric heating.

No.

Fire hydrant, officially known as fire hydrant, is a fixed fire-fighting facility, the main function is to control the return of combustibles, isolate combustibles, and eliminate the source of ignition. It is divided into indoor fire hydrants and outdoor fire hydrants.

Article 28 of the Fire Protection Law stipulates that no unit or individual shall damage, embezzle, or dismantle or stop using fire-fighting facilities and equipment without authorization, shall not bury, occupy, or block fire hydrants or occupy fire spacing, and shall not occupy, block, or close evacuation channels, safety exits, and fire truck passages.

Fire hydrants should be placed in public shared spaces such as corridors or halls, and generally in the walls of the above-mentioned spaces"Fire hydrants"and shall not set up obstacles in front of it to avoid affecting the opening of the fire hydrant door. Fire hydrants are generally not located in rooms (such as boxes), which do not meet the regulations of fire protection and are not conducive to the timely rescue of firefighters.

The southern region does not need it, but the northern region needs it, and it should be combined with the actual local climate conditions.

It's all about keeping warm!

I don't know what the temperature in your thermal pipe is, if you don't do it, it will consume a lot of heat in the process of transmission.

That kind of insulation is set in, so you have to put it in before you can bury it, but there are some that are not sold underground, our school is to make a pipe ditch, covered, anyway, it should not be too exposed, which will make those insulation materials easy to age and then break.

(1) As long as the buried depth is below the permafrost, it is not needed, but if the permafrost is very deep, the buried depth cannot be reached, and it needs to be insulated. Generally, the effect of polyurethane is better.

2) In addition, even if the tap water is buried below the permafrost, the part that enters and exits the ground is to be out of the permafrost or even the ground, so it is necessary to do a good job of insulation.

There are special pipes, and the middle of the double-layer pipe is filled with insulation material.

If you bury it below the freezing line, you can do it without it.

Water pipes do not need to be insulated below the permafrost...

However, the cooling or heating pipeline, whether buried in **, needs to be insulated...
