No matter whether they are built on the streets or anywhere else, as long as they are pipes that play a role in drainage, they are classified as drainage pipes. The water supply and drainage system is extremely important in buildings. The water supply and drainage pipes are mainly used to supply water to the interior of the building or to discharge the wastewater produced in the building.

However, when the porous phenolic foam is damaged and the sound-absorbing effect is reduced, it is inconvenient to replace the porous phenolic foam. In order to maintain a good sound-absorbing effect, it is necessary to replace a new drainage pipe, which leads to waste.
