Sound insulation and sealing of the risers of the heating system and water supply

In accordance with building codes, the risers of the water supply and heating pipelines should be laid through the interfloor ceilings using vibration-proof sleeves. To do this in the ceiling, you must install a metal pipe, the diameter of which is larger than that of the riser. The gap between the pipes is filled with non-flammable sound-absorbing material, additionally conducting sealing non-hardening sealant.

But in reality, these works are sometimes not done - the use of mineral wool or shells is simply forgotten. As a result of this, after several years of operation, gaps are formed between the floor slab and the riser pipe, which are sources of not only extraneous noise, but also unpleasant odors.

To solve this problem, you can use two methods. In the event that the riser passes through the coating in the liner, then you need to carefully seal the gap between the riser and the liner with a heat-resistant silicone sealant. If the riser passes directly through the overlap, then next to the pipe should be thoroughly cleaned and remove the damaged layer of cement mortar to the maximum depth, preventing ingress into someone else's apartment.

After that, the base of the pipe is wrapped with sound-insulating material and cementing the damaged area. The excess sound insulation is removed, and then the joint is sealed with silicone sealant.

FIRE FIGHTING BOX FOR DRAINAGE

In addition to soundproofing and sealing, sewage plastic risers should be mounted with fire fighting couplings.

Fire seals on sewers are designed to prevent the spread of fire as a result of deformation of the polymer pipe under the influence of open fire. The melting point of the material is 180 ° C. At higher temperatures, the pipe simply burns out and provides free access to the fire in the neighboring rooms.

Installing fire couplings on sewage pipes helps to prevent the spread of fire. In PPM is a substance that when heated increases in volume up to 10 times. The expansion is directed both inwards and outwards of the pipe. Thus, the fire sewer coupling closes the opening in the floor slabs, limiting the additional access of oxygen to the room, which is the epicenter of the fire.
