The advantages of pvc water pipe

It has good tensile and compressive strength.

Low fluid resistance: the wall of PVC water pipe is very smooth, the resistance to fluid is very small, its roughness coefficient is only 0.009, its water transfer capacity is 20% higher than that of cast iron pipe of the same diameter, and 40% higher than that of concrete pipe.

Excellent corrosion resistance and drug resistance: PVC water pipe has excellent acid resistance, alkali resistance, corrosion resistance, is not affected by moisture and soil pH, pipeline laying does not need any anti-corrosion treatment.

With good water tightness: the installation of PVC water pipe, whether using adhesive or rubber ring connection, has good water tightness.

Bite proof: PVC water pipes are not a source of nutrients, so they are not susceptible to erosion by rodents. Rats won't gnaw on PVC water pipes, according to a study conducted by the National Foundation of Health in Michigan.

Application
PVC drainage pipes have been more and more widely used in various industries. The main material of PVC drainage pipes is polyvinyl chloride. PVC has strong heat resistance and corrosion resistance. This is why PVC drainage pipes have strong heat resistance and corrosion resistance. One reason for its widespread use.
In order to make the facade of the building more beautiful, indoor rainwater drainage systems are more and more widely used. Indoor rainwater pipes are generally designed according to unpressurized flow, but because the rainwater flow is sometimes large and concentrated, at the same time in the pipes There are two states of gravity flow and pressure flow, so indoor rainwater pipes are required to have stronger pressure resistance than other drainage pipes.
PVC drainage pipe is a substitute for traditional drainage pipes and has better physical and chemical properties. Its inner wall is smooth and has less friction resistance than conventional drainage materials. Therefore, the installation slope of the horizontal pipe is smaller, which can increase the indoor clear height of the building. At the same time, PVC drainage pipes are lighter in weight, one-fifth of cast iron pipes, and are easy to transport and operate; they are adhesively connected for easy installation and maintenance; they are cheaper than conventional drainage pipes, greatly reducing project costs; they have strong corrosion resistance and are used in construction Sewage, wastewater and rainwater pipe systems are widely used. In addition, the widespread use of PVC drainage pipes is conducive to saving steel and is of great significance for alleviating the shortage of steel in our country. Compared with cast iron pipes and steel pipes, PVC-U drainage pipes have the ability to withstand It has the disadvantages of low pressure and weak impact resistance. In addition, although PVC-U drainage pipes are flame-retardant materials, for indoor exposed pipes, there is a possibility of fire spreading upward along the drainage riser.
