Pipe spacing
Thread Content
Are there any specific requirements for the spacing between pipeline casings passing through fire breakers?
Just determine the distance between main pipes and the distance between casings as long as they can ensure installation.
Look at the construction method of firewall perforations: 1. If all the perforations use a large waist-shaped hole, ordinary pipe spacing can be installed. 2. If each perforation is required to use a separate round hole, the spacing must be arranged according to the civil construction requirements.
In which specification did you find the above content?
Encountered in actual work, haha: lol
Generally it should be 1-2 levels older so it is easier to do this! ! ! ! In addition, the effect is not bad! ! ! :handshake:victory:
As long as the casing is not touched and the construction is not affected.
Generally, the casing is one or two levels larger than the pipe.
What is the fluid medium in your pipeline? It is necessary to confirm whether there are specific requirements for the spacing between pipeline casings crossing the fire embankment according to the fluid pipeline fluid medium and the corresponding specifications! (For example, if it is a drainage pipe, the requirements are not so strict. If it is a gas pipe, the requirements are still the same. * * Current norms and standards) Hahaha:) :lol :lol :)
Considering the center distance according to the pipeline, the buried pipe is one level larger than the process pipe.
There should be no requirements in terms of craftsmanship, as long as it can be easily installed! I don’t know what the requirements are for other majors.
Combustible gas and liquid pipelines shall be spaced according to the standard spacing or the casing spacing, whichever is greater. Ordinary fluids do not touch the casing, making it easier to control during construction.
The distance between pipelines, whether they are bare pipes or insulated pipes, is 100-150mm based on the outermost layer to facilitate construction and maintenance. The distance between pipelines, equipment, and buildings is related to the medium transported by the pipeline, as well as the pressure and temperature levels, and is stipulated in relevant specifications.
