It is not unnecessary to install "fire-retardant rings" on plastic drainage pipes. Fire-retardant ring manufacturers

The important role of installing fire-retardant rings on plastic drainage pipes, fire-resisting ring specifications, fire-resisting ring manufacturers, it is not unnecessary to install fire-resisting rings on plastic drainage pipes
- Our plastic drainage pipes in high-rise buildings You can often see a small metal component installed at the bottom of the floor slab. This small metal component is the fire-retardant ring.

- "Construction Quality Acceptance Code for Building Water Supply, Drainage and Heating Projects" Article.. Explicit drainage plastic pipes in high-rise buildings should be equipped with fire-retardant rings or fire-proof casings according to design requirements.
- In the explanation of this article, it is also stated that in high-rise buildings, there are exposed drainage pipes and fire-stop rings or fireproof casings under the floors to prevent the plastic pipes from being burned and the fire passing through the floors to spread the fire. to other layers.
- It can be seen from this that the fire-stop ring installed on the plastic drainage pipe is not unnecessary.
- The specification obviously provides options, but in actual operation, setting up a fire-retardant ring is the main option. So, what size of plastic drainage pipe does it need to be equipped with a fire-retardant ring or fire-proof casing? This specification does not explain it, so some installers are at a loss.
- In fact, the industry standard of the People's Republic of China - "Technical Regulations for Construction Drainage Rigid Polyvinyl Chloride Pipe Engineering" - has made more detailed provisions on this, and the two can corroborate each other.
- It is said in Article .. that when exposed pipes in high-rise buildings are designed to prevent fire penetration, they should comply with the following regulations:
- The riser diameter is larger than or equal to When equal to ㎜, a fire-retardant or fireproof casing with a length of not less than ㎜ should be installed at the penetration part of the floor
- This one is for the riser, and the second and third ones are for the horizontal pipe. There are also requirements for setting up fire-stop rings.
- When a cross-branch pipe with a pipe diameter greater than or equal to mm is connected to a concealed pipe, a fire-retardant ring or a fire-proof casing with a length of not less than 3 mm should be installed at the penetration part of the wall, and the exposed part of the fire-proof casing should be installed The length should not be less than mm.
- When the horizontal main pipe passes through the fire partition wall, fire-stop rings should be installed on both sides of the wall where the pipe passes or the length should be no less than mm.
- Through the study of the above specifications and standards, we know the function and installation location of fire-resisting rings. We know that not only fire-resisting rings are provided on the risers, but also on the horizontal pipes that penetrate the wall. In addition, some drainage risers are installed in pipe wells, so the horizontal pipes entering the pipe well must also be equipped with fire-retardant rings close to the wall.
- Some buildings also add fire-stop rings to outdoor plastic rainwater risers, which is obviously superfluous.
