What are Plastic pipes and fittings?
Plastic pipes and fittings refer to pipes and related connecting parts made of plastic materials, which usually include polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), ABS, polybutylene (PB), etc. Plastic pipe fittings are favored in pipeline engineering because of their light weight, corrosion resistance, sanitation and safety, low water flow resistance, energy saving, and metal properties. Plastic pipes are widely used in many fields, including water supply, drainage, gas, floor heating, power communication, agriculture, and other fields.
The accessories of plastic pipes mainly include various types of joints, valves, flanges, etc. These accessories are used to connect, control, or change the direction and flow of pipes. The selection and use of accessories are essential to ensure the safety and efficiency of the system. Plastic pipe systems occupy an important position in modern buildings and infrastructure because of their easy installation and maintenance, as well as good corrosion resistance. In addition, the use of plastic pipes can also reduce dependence on metal resources, which is conducive to environmental protection and sustainable development.
What are the differences between Plastic pipes and fittings of different materials?
PVC (polyvinyl chloride) : PVC is the most used plastic in construction, mainly used in electrical wiring and plumbing, and sewage pipes. It has good acid and alkali resistance, wear resistance, and electrical insulation, but does not burn, has poor thermal stability and light resistance, low softening temperature, limited to use below 80 ° C. PVC pipe is commonly used in non-pressure piping systems such as drainage and electrical piping .
PE (polyethylene): PE pipes have good chemical corrosion resistance and are widely used in various pressure piping systems. It is odorless, tasteless, non-toxic, has excellent mechanical properties, and good heat resistance, and the continuous use temperature can reach 110-120°C. PE pipes are suitable for various industrial and civil piping systems due to their excellent heat resistance and chemical stability.
PP (polypropylene): PP pipes are odorless, tasteless, non-toxic, have good heat resistance and chemical stability, and do not react with most chemicals except strong oxidants. It has good water resistance and electrical insulation, but is easy to age and has poor impact strength at low temperatures. PP pipes are widely used in drinking water supply systems, chemical industry pipelines, etc.
ABS (Acrylonitrile-Butadiene-Styrene Copolymer): ABS pipes have excellent comprehensive properties, including good rigidity, hardness and processing fluidity, as well as high toughness. ABS pipes are easy to process, have excellent dimensional stability and surface gloss, and are suitable for the field of electronics and electrical appliances, including the housings of various office and consumer electronics/electrical appliances.
Advantages
1. Environmental protection: Plastic pipes and fittings are environmentally friendly and non-toxic, meet modern environmental protection requirements, do not release harmful substances, and are suitable for application scenarios that require high safety such as water supply.
2. Durability: With excellent anti-aging and corrosion resistance, it can be used in various harsh environments, ensuring long-term stability and long service life.
3. Economy: The production cost of Plastic pipes and fittings is relatively low, the price is economical, and it can meet the needs of large-scale engineering construction.
4. Easy installation: Compared with traditional metal pipes, plastic pipes are lighter, easier to install, do not require professional skills, and reduce the difficulty of construction.
5. Wide application fields : widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, power and optical cable sheathing, industrial fluid transport, agricultural irrigation and other fields .
6. Good appearance effect: plastic pipe fittings have a smooth, neat appearance and rich colors, which can enhance the beauty of buildings and are favored by designers.
