Pipe sleeves are used in construction to keep a pipe hole open, fill the space between a pipe and another surface, or create a barrier between a pipe and the surrounding environment. They can be made from various materials and protect against odor, fire, and environmental damage.
A pipe sleeve is generally one of three things: a protective ring used to keep a pipe hole open, a ring used to fill the space between a pipe and another surface, or a cap to create a barrier between a pipe and the other surface. surrounding environment. These sleeves are used during the construction of a building or piping system. Almost all non-household piping systems have some sort of sleeve, and many of the household ones do too.
This first type is commonly used during the construction or renovation of a building. These sleeves are rings that are inserted into forms for a concrete wall. When the wall is poured, the form creates a hole large enough for a pipe to pass through. It is generally much larger than the pipe that will pass through it and creates a gap.
The second type of pipe sleeve is used during the construction of a building or after the building is finished. These types fill the spaces where the pipes enter the walls and create a barrier between the two sides through which air cannot pass. They can be made from many different materials, including polyvinyl chloride (PVC), sheet metal, or firestop material.
The two main reasons for using this type of sleeve are to protect against odor or fire. When the sleeve is around a water pipe, that pipe will eventually end up in the sewer. By placing an airtight seal around the opening in the floor around the pipe, the sewage smell will not recirculate around it. Firestops work on the same idea, except they stop the fire rather than the smell. When hot air from a fire tries to move up and out, it would naturally draw the fire through the spaces around the pipe, spreading the fire faster.
The latter type of pipe sleeve is often worn during construction, but its purpose is afterward. These sleeves protect the hose from the environment or vice versa. The most common varieties are protective and insulating. A protective case prevents damage from accidental bumps in high-traffic areas.
Some pipes carry very hot or cold materials. In some cases, it’s critical that these materials remain at their current temperature, so an insulating sleeve maintains the temperature inside the pipe. On the other hand, those same materials could affect the temperature of the surrounding environment or cause burns if touched. Pipe sleeves also protect against this.
