Water well drilling PVC Pipe casing and borehole pvc casing tube screen for well drilling with thread connection

PVC drainage pipes have been increasingly used in various industries. The main material of PVC drainage pipes is polyvinyl chloride. PVC has strong heat resistance and corrosion resistance.

PVC slotted (bored) characteristics

1. Resistant erode

PVC pipe has stable chemical property, which can resistant most of acid and alkali,

2. Service life long

Traditional pipe service life is 20-30 years. PVC pipe service life is at least 50 years at a set temperature and pressure.

3. Excellent sanitary performance

PVC pipe is produced by used Tin or Ca/Zn stabilizer, its sanitary performance is full according to GB/T17219 standard and Ministry of Health of the People’s Republic of China related water criterion.

4. PVC pipe has better slotted (bored) rate, strong resistant pressure, larger cross flowing, and is the best choice replace steel and concrete slotted (bored) pipe in many fields.

5. Easy installing

PVC slotted (bored) pipe joint form: elastic seal ring joint, cement joint, also crew joint and flange joint. In additional, PVC-M pipe is density low, weight light, lower requirements for worker and construction equipment, construction cost also is lower compared concrete pipe, steel pipe.

6. Inside wall smooth, no furring, flowing easier, no block(n=0.008---0.009),excellent resistant bacteria. It can effectively guarantee pipes long time straightway. For turning over swash field, PVC-M pipes also easily wash clear.

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.
