PVC-U pipes are made of sanitary polyvinyl chloride (PVC) resin as the main raw material, with appropriate amounts of stabilizers, lubricants, fillers, color enhancers, etc., extruded by a plastic extruder and injection molded by an injection molding machine. , curing, shaping, inspection, packaging and other processes to complete the production of pipes and fittings.

Compared with traditional pipes, PVC-U pipes have the advantages of light weight, corrosion resistance, small water flow resistance, energy saving, quick installation, and low cost. They have been vigorously promoted and applied, and the benefits are significant. Widely used in: urban tap water supply projects, building internal and external water supply projects, industrial and mining enterprise water supply projects, underground fire water supply projects, farmland water conservancy and irrigation projects, gardening and greening water supply projects, aquaculture water supply and drainage projects, etc., and have obtained Good economic and social benefits.

FREQUENTLY ASKED QUESTIONS



What are the common specifications of PVC pipe drainage pipes?

The conventional specifications of commonly used PVC pipe drainage pipes are as follows: nominal outer diameters are: 32mm, 40mm, 50mm, 75mm, 90mm, 110mm, 125mm, 160mm, 180, 200mm, 250mm, 315mm, 400mm, 500mm, 630mm, etc. PVC-U The length of the pipe is generally 4m or 6m, and customization is supported



How to solve the expansion and contraction problem of PVC drainage pipe?

The linear expansion coefficient of PVC drainage pipes is large, and expansion joints need to be installed during construction to solve the expansion and contraction problem. According to the calculation formula for the expansion and contraction of PVC-U drainage pipes caused by changes in ambient temperature:

△L=L·a·At

In the formula, △L-pipe expansion and contraction amount (m);

L-pipe length (mk)

a-Linear expansion coefficient, adopt 6×10-5～8X10-5-m/(m·℃);

△t-Temperature difference (℃)



What is the main use of PVC drain pipe?

Collect and remove wastewater, rainwater and sewage generated within the building. In urban infrastructure, drain pipes are used to collect drainage from roads, bridges, and other buildings. Drain pipes can also be used to vent gases, such as smoke exhaust ducts in kitchens and bathrooms.



What material is PVC drainage pipe made of?

PVC drainage pipe is a pipe material made of polyvinyl chloride resin as the main raw material. PVC pipes are easy to install, have a long service life and are simple to maintain, making them an ideal choice for modern building drainage systems.



What are the advantages of PVC drain pipes?

1. The surface hardness and tensile strength of the pipe are excellent, and the pipeline safety factor is high.

2. PVC drainage pipes have good aging resistance and their normal service life can reach more than 50 years.

3. The pipeline has excellent corrosion resistance to inorganic acids, alkali and salts, and is suitable for industrial sewage discharge and transportation.

4. PVC drainage pipes have a small friction coefficient, smooth water flow, are not easy to block, and require less maintenance work.

5. PVC drainage pipe material has a high oxygen index and is self-extinguishing.

6. The linear expansion coefficient of the pipeline is small, 0.07mm/℃, and the deformation affected by temperature is small. The thermal conductivity and elastic modulus are small, and compared with cast iron drainage pipes, they have excellent freezing resistance.

7. Bonding can be used to connect pipes and pipe fittings. The construction method is simple, the operation is convenient, and the installation efficiency is high.
