Applications and connection method of PVC pipes

PVC pipe is one of the most familiar pipes,Do you know its application and connection method?

Performance characteristics of PVC pipes

1. Lightweight, convenient for handling and loading/unloading

PVC plastic pipes are lightweight, with a specific gravity of only 1/5 of iron pipes. They are easy to handle, load and unload, and can save construction costs;

2. Excellent corrosion resistance and drug resistance

PVC plastic pipes have excellent acid resistance, alkali resistance, and corrosion resistance, and are widely used in chemical industry, wastewater drainage, sanitary sewer and other fields;

3. Low fluid resistance

PVC plastic pipes have smooth inner walls and low fluid resistance, with a roughness coefficient of only 0.009, which is lower than other pipes. Under the same diameter, the flow rate is larger and there is no scale attached;

4. High mechanical strength

PVC plastic pipes have good performance in water pressure resistance, impact resistance, etc., and are suitable for various piping engineering conditions at room temperature;

5. Excellent electrical insulation

PVC plastic pipes have superior electrical insulation properties and are suitable for wire and cable sleeves. They can be widely used in telecommunications, power piping, and wire piping in buildings;

6. Not affecting water quality

The results of the dissolution test confirm that PVC plastic pipes do not affect water quality and have no problem of producing "red water", making them the best pipe material for water pipes at present;
7. Easy construction

The connection methods for PVC pipes mainly include the following:

Hot melt connection. This method is suitable for situations where the diameter of the pipes matches. Firstly, heat the two pipes to a softened state, then quickly connect them together. After cooling, the pipes will be firmly connected together.

Socket connection. Suitable for situations where the pipe diameter matches. Firstly, the connecting end of the pipe needs to be polished smooth to remove burrs, and then a section of the pipe needs to be inserted into the socket of the other end of the pipe. This connection method is simple and fast.

Sealing rubber ring connection. Suitable for PVC pipes with larger diameters. Place a rubber ring at the connection and apply some lubricant to the edge, then insert the water pipe into the pipe opening.

Glue connection. Suitable for PVC pipes with smaller diameters. Apply PVC adhesive to the connection, then connect the two sections of pipes together and wait for the adhesive to dry. The pipes will be firmly connected together.

Flange connection. Suitable for connecting metal pipes and PVC pipes. Connect metal pipes and PVC pipes through flange connectors, which is suitable for connecting pipes of different materials.

Each connection method has its own applicable scenarios and operational steps. When selecting the appropriate connection method, it is necessary to consider the diameter, material, and connection requirements of the pipe.
