Gray UPVC plastic irrigation pipe
UPVC Plastic irrigation pipes have been widely used at home and abroad, because plastic irrigation pipes have many advantages over traditional irrigation pipes such as cast iron pipes, steel pipes and cement pipes:
1. Strength and rigidity
On the surface, the strength and rigidity of UPVC plastic irrigation pipes are not as good as that of cement pipes, especially reinforced concrete pipes. In fact, plastic buried pipes belong to “flexible pipes”. Under the correct design and laying construction, plastic buried pipes bear the load together with the surrounding soil. Therefore, plastic buried pipes do not need to reach the same strength and rigidity as “rigid pipes” such as concrete pipes, so they can meet the requirements of burying Mechanical property requirements in use.

2. Hydraulic characteristics
The inner wall of plastic irrigation pipe is smooth, the resistance is small, and the flow flux is large.
3. Tightness
The leakproofness of cement pipe is very poor. Only one circle of concrete is applied to the joint of domestic plain joint concrete pipe, so it is difficult to ensure that there is no leakage during construction. In addition, the rigid pipe of concrete pipe system can cause damage to the joint if it moves slightly (such as uneven settlement of soil). In addition, the cement pipe is sealed with vulcanized rubber ring, and the plastic irrigation pipe is sealed with thermoplastic elastomer ring, the former The service life is shorter than the latter, and there are a series of strict requirements for the connection and sealing of plastic pipes, which can ensure that no leakage will occur to the greatest extent.

4. Service life and corrosion resistance
The life of cement pipe is only 15 years, and that of plastic pipe is 50 years-
100 years. The domestic sewage and rainwater are usually corrosive, and the industrial sewage is more corrosive. The metal and cement buried drainage pipes are used for transportation, and the corrosion resistance is worse than plastic pipes.

5. Laying construction
Plastic irrigation pipe is light in weight, large in length, few in joints, low in requirements for pipe trench, convenient in connection, fast in construction, low in construction cost, and more prominent in urban and harsh natural conditions.

6. Comprehensive economy
In terms of comprehensive economy, the advantages of plastic irrigation pipes are being recognized by more and more users. Although the unit price of plastic irrigation pipe is slightly higher than that of cement pipe, the total project cost is not higher than that of cement pipe.PVC-U Pipe factory
