Some PVC sleeves are produced in the market by mixing them with other materials. Typically, composite pipes combine metal materials and pigments reasonably to fully utilize the good mechanical properties of metals and the anti-corrosion properties of plastics, thereby ensuring that PVC pipes have double-layer properties and product quality is further strengthened. The development of PVC pipes needs to limit and gradually eliminate old pipes that do not meet development requirements. Developing new types of pipes with excellent performance and good corrosion resistance, selecting appropriate metal or non-metallic pipes according to actual requirements, and producing products that meet the environmental requirements of the European Union, in order to be competitive in the international market. With the development of the economy, decoration of houses is also increasingly valued for aesthetics. Previously, it was OK to directly install points on walls, but later it developed to use pipes to connect wires in series, Nowadays, it is generally used to buy wire and bury it in the wall, which requires the use of PVC casing. In the early stages of house construction, the wires are threaded into the casing, and then the installed casing is buried in the wall, which is more conducive to the beautiful decoration of the house.

A home theater will inevitably have a TV, DVD+amplifier, and audio system, which will definitely require a lot of wires when splicing. If PVC conduit is not used for layout, it will have a significant impact on the aesthetics of the house. Before starting to build a home theater, there are many factors to consider, such as the positioning of the space used, whether it is the living room or study, such as the size of the area, using a projector for larger ones, and using a flat screen TV for smaller ones, In addition, furniture selection, background wall design, and building a perfect home theater require not only financial investment, but also energy preparation that is not afraid of trouble.
