Generally speaking, what kind of pipe is used only refers to the main material, and then usually the accessories with the same material are used. According to the actual market situation, it is not a big problem to adopt general materials.
Unless it is industrial or special water supply, it will be indicated that certain materials must be used.
PPR SW pipe is a new type of high temperature and oxygen resistant composite pipe.
The product consists of two layers of materials, the inner lining material is PPSU, PES and other high-temperature polymerized raw materials, and the outer layer material is trackless polypropylene (PPR), which meets the technical requirements of GB/T 1874.2-2002.
materials performance
The outer material of this product is composed of random polypropylene (PP_R). PP-R material has been widely recognized in the world, and is widely used in water supply system. The inner layer material is composed of patented composite material. This composite material has a stable structure, which improves the physical temperature resistance and pressure resistance of a single material, and is characterized by no pollution to water quality (at present, there are many plastic materials used in the water supply system, and the water quality will be diluted by plastic materials in long-term contact with water molecules, including heavy metals and other substances harmful to human health, which will cause secondary pollution. Because of high-temperature polymerization, the inner layer material has compact intermolecular composition, very stable physical properties, no pollution to water quality, and can reach the level of pure water, which is more in line with modern health concepts and is the ideal first choice material for water supply system.

At present, there are not many manufacturers and nothing special. Why use such a special material? I can't find any accessories.
I don't know if you are a contractor or a budget. It's best to call the designer directly to ask.
