Which types of drainage pipes are included
1, PP, formerly known as polypropylene, is a special type of drainpipe material. Its main characteristics are high hardness, heat resistance, non-aging, and relatively small density.
2, PVC, commonly known as polyethylene, is a polymer material. It is also the most unique of the drainpipe materials.
3, PE, commonly known as polyethylene, is specially used for building water supply, drainage, trachea, heating, electrical, agricultural and industrial materials.
4, plastics, in fact, is a kind of resin based on the addition of various Auxiliaries, fillers and reinforced materials, etc., under a certain technical process to process and mold a solid material.
Stainless steel, as its name implies, is a kind of steel pipeline that does not rust. It is mainly used to transport fluids such as water, oil, neat, natural gas, and so on.
6, PBCs:(1) Good durability, non-toxic and harmless: because it is a high-density polymer, the molecular structure is stable, the service life can reach 50-100 years, and non-toxic and harmless, no chemical reaction occurs; (2) Good thermal resistance: At -20 °C, it has a good low-temperature impact resistance, and the pipe will not freeze and crack. After thawing, the pipe can be restored to its original state and can withstand high temperatures below 100 °C.
7, PPR tube: the current relatively perfect water pipe, non-toxic, corrosion resistance, hot melting seamless connection, can be used for hot and cold water pipes, but also can be buried. PP-R tubes are also commonly referred to as heat melt tubes because they use bonding technology in construction.
What are the conditions for using outdoor drains
1, the inner wall is smooth, with corrosion resistance, erosion resistance.
2, a certain degree of mechanical strength, withstand the ability of the soil and ground load.
3, anti-seepage ability. Outdoor drainage pipes commonly used include: concrete pipes, reinforced coagulation upper pipes, drainage cast iron pipes, rigid polyvinyl pipes, glazed cylinder tile pipes, etc.. More than 400 reinforced concrete pipes are used for concrete pipes, often used in rain. Sewage system.
