What is upvc pipe?

UPVC pipe, full name of hard polyvinyl chloride pipe, is a plastic pipe widely used in modern construction and engineering fields. It is a new type of pipe made of polyvinyl chloride (PVC) resin as the main raw material and processed by special technology. UPVC pipe not only has the advantages of being lightweight, corrosion resistance, and easy installation, but also has significant advantages in service life and environmental protection, so it is known as a “green building material”.

Difference between PVC and UPVC pipe

UPVC pipe: the full name of hard PVC pipe, is the upgrade of PVC pipe products. No plasticizer is added to UPVC, so its material is more stable and has higher hardness and strength.

PVC pipe: Full name polyvinyl chloride pipe, is a widely used plastic pipe. Plasticizers are added to PVC raw materials, and these plasticizers may not be fully volatilized during processing, which may have a certain impact on the performance and safety of the pipe.

upvc pipe features applications

1. The main raw material of UPVC pipe is polyvinyl chloride resin, which does not contain plasticizers during processing, so it has extremely high stability and corrosion resistance. It can effectively resist the erosion of acid, alkali, salt, and other chemical substances, will not rust, will not scale, so as to protect the water quality from secondary pollution. This characteristic makes UPVC pipe widely used in tap water distribution engineering, building water supply and drainage system, water-saving irrigation system and other fields.

2. Another notable feature of the UPVC tube is its smooth inner wall and low fluid resistance. Because the inner wall of the pipeline is smooth, the liquid will not form scale when flowing in the pipeline, thus ensuring the smooth transmission of the fluid. This feature makes the UPVC pipe transport of the same liquid, as traditional pipe such as galvanized pipe, cast iron pipe resistance is about 30% less, and water transmission capacity increased by more than 20%. In addition, UPVC tube also has good insulation properties and electrical resistance properties, making it widely used in electrical wiring tubes, post and telecommunications cable conduits, and other fields.

3. UPVC tube installation and maintenance is also very convenient. Because of its lightweight, easy handling, and installation, it can greatly reduce the labor intensity of workers and shorten the construction period. At the same time, UPVC tubes have excellent aging resistance and can be used for 20 to 50 years between -15 ° C and 60 ° C, with long service life and low maintenance costs. This makes UPVC pipe widely used in construction projects, especially in the need for rapid construction and long-term use.

4. In addition to the above advantages, UPVC tubes also have environmental performance. In the production process, the UPVC tube does not produce harmful substances and will not pollute the environment. At the same time, due to its excellent corrosion resistance and long service life, the frequency of tube replacement is reduced, thus reducing resource consumption and waste emissions. This makes UPVC pipe an ideal green building material in today’s vigorously promoting the production of environmentally friendly products.

Limitations of the upvc pipe

UPVC tubes also have some limitations. For example, its heat resistance is poor, suitable for continuous discharge temperature does not exceed 40 ° C, and instantaneous discharge temperature does not exceed 80 ° C domestic sewage. In addition, the toughness of the UPVC tube is low, and the coefficient of linear expansion is large, which needs to be considered in the design and use.

In summary, UPVC pipe has been widely used in modern construction and engineering fields due to its excellent corrosion resistance, smooth inner wall, easy installation, environmental protection performance, and other advantages. With the continuous development of chemical industry technology, the performance of UPVC tubes will be further improved, and the application field will be more extensive.
