PVC pipe performance and use
Features of PVC pipes:
1. The proportion of PVC material is 1/10 of that of iron, which is relatively simple in transportation and installation;
2. Low cost, excellent acid and alkali resistance, and good chemical properties;
3PVC is an anti-static material that can't conduct electricity, and is not subject to electrolysis and current corrosion;
4. PVC material has good anti-static properties and good flame-retardant properties. It is a double-resistant pipe;
5. It can be used for underground coal mine drainage and water supply, gas drainage and air exhaust;
6. Low resistance and high flow rate: smooth inner wall, low fluidity loss, and dirt is not easy to adhere to the smooth pipe wall.
7. Flame-retardant and anti-static: Polyethylene resin, which is a special material for coal mine pipes with flame-retardant and anti-static properties, is used as the main material, and steel belt is the reinforcement.
8. Good anti-aging and anti-cracking performance:
9. Corrosion resistance, not easy to scale: The comprehensive economic benefit is about 5-8 times that of steel pipes.
10. Lightweight and easy to install: the specific gravity of the pipeline is about 1/6 of that of steel pipe and 1/3 of that of glass steel pipe. Flanged connection is adopted for underground construction. PVC pipes can be used in the laying of underground coal mines, such as gas drainage, positive pressure ventilation, negative pressure ventilation, water supply and drainage, and shotcrete.
Precautions for use of threading pipe
| 1. |
can not without reason winding, this will not only cause dead wire, but also increase the input of electricity reform. |
| 2. |
Do not wear too much thread in a threading tube. After threading, you should drag it to see if it can be easily pulled. |
| 3. |
If the line has joints, it is necessary to leave the black box buckle panel at the joints, which is convenient for replacement and maintenance in the future. |
