1. It has good tensile and compressive strength, but its flexibility is not as good as other plastic pipes.
2. Low fluid resistance: the wall of PVC-U pipe is very smooth, and the resistance to fluid is very small, and the roughness coefficient is only 0.009. Its water delivery capacity can be increased by 20% compared with the same caliber cast iron pipe and 40% compared with the concrete pipe.
3. Excellent corrosion resistance and drug resistance: PVC-U pipe has excellent acid resistance, alkali resistance and corrosion resistance, and is not affected by moisture and soil pH, so there is no need for anti-corrosion treatment when laying pipes.
4. Good watertightness: The installation of PVC-U pipe has good watertightness whether it is connected by adhesive or rubber ring.
5. bite prevention: PVC-U tube is not a nutrient source, so it will not be eroded by rodents. According to the detection of relevant institutions, rats will not bite PVC-U tubes.
Shortcomings of pvc water pipes
Pvc water pipes are not as flexible as other plastic pipes.
Thermal stability and impact resistance are poor, and both rigid and soft PVC are prone to brittleness during use. It will do harm to the human body.
PVC water pipes can only be used for water supply and drainage, not for hot water.
The connection of PVC water pipes can't be made by hot melt process, only PVC glue can be used.
Application of PVC water pipes;
1: Application in the field of home improvement
Different from PPR, PPR is mainly used for water pipes, while PVC can only be used for water pipes. Unless the budget is limited, Laojin does not recommend using PVC water pipes in the field of home improvement, but suggests using PVC water pipes in some balcony faucets (washing machines) or bathrooms.
The specifications of PVC water pipes commonly used in home decoration are 20mm/25mm/32mm, and the most commonly used color is gray; In addition, electrical pipes are the most commonly used in home decoration. The most common specification is 16MM/20MM (to be discussed later). There are three colors: red, blue and white. In addition, the most commonly used accessories such as kitchen and toilet are PVC.

Friends must pay attention that PVC pipes or fittings can only be used in PVC materials and cannot be mixed with PPR. Because of the different materials, they can't be used universally. Remember! !
The knowledge of PVC water pipes is all here, so you don't have to worry about being fooled anymore.

2. The use of sewage buildings.
Large diameter PVC pipes are generally used for sewage discharge and rainwater drainage in rural houses or villas, because most of them are white when installed outdoors. The most commonly used specifications are 50 mm/75 mm/110 mm/160 mm, and the commonly used accessories are straight-through, tee, four-way, floor drain, S-shaped storage compartment and different straight-through.

How to distinguish the quality of PVC water pipes;
To distinguish the quality of PVC water pipes, follow the following five steps. Laojin guarantees that even Xiaobai can buy PVC water pipes with good quality and excellent price: one quantity, two looks, three balances, four falls and five tests.
