Fitting cover

Abstract

This article is a joint cover that covers the outer surface of a joint that connects pipes. As shown in the reference enlarged view of the AA part, this article is made by laminating and bonding a sound-absorbing foam layer, a sound-proof sheet layer, a nonwoven fabric sheet layer, and an aluminum sheet layer that forms the outer surface side of the joint. As shown in Reference Figure 1, which shows the usage state, this article has holes through which cylindrical protrusions that protrude outward from the outer surface of the joint can be inserted, and covers the outer surface of the joint with the protrusions of the joint inserted through the holes, as shown in Reference Figure 2, which shows the usage state, and Reference Figure 3, which shows the usage state.
