How to connect PVC water pipe

In home decoration or engineering construction, the connection of PVC water pipes is a common and important link. The correct connection method not only ensures the sealing of the water pipe system, but also extends its service life. This article will introduce in detail the connection method of PVC water pipes, and attach relevant data for reference.

1. Preparation work before connecting PVC water pipes

Before connecting the PVC water pipe, you need to make the following preparations:

1.Check materials: Ensure that the specifications and models of PVC pipes and fittings match and are not damaged or deformed.

2.Clean pipes: Use a clean cloth to wipe the connection parts of pipes and fittings to avoid dust or impurities from affecting the sealing effect.

3.Preparation tools: Including PVC glue, cutting tools, measuring tools, etc.

2. Connection method of PVC water pipes

There are mainly the following ways to connect PVC water pipes:

1.Glue bonding method: This is the most commonly used connection method and is suitable for PVC pipes with smaller diameters. The specific steps are as follows:

- Apply PVC glue to the joints of pipes and fittings.

- Quickly insert the tubing into the fitting and rotate 90 degrees to ensure even distribution of glue.

- Keep it fixed for a few seconds until the glue sets.

2.Flange connection: Suitable for PVC pipes with larger diameters, usually used for connection with valves or other equipment. The specific steps are as follows:

- Secure the flanges to both ends of the pipe.

- Bolt the two flanges together.

3. Precautions after connection

1.Check tightness: After the connection is completed, a water pressure test is required to ensure there is no leakage.

2.Avoid external impact: Avoid applying gravity or external force to the pipe until the glue has completely cured.

3.Regular maintenance: Regularly check the pipe connection parts and deal with them promptly if any looseness or leakage is found.

4. Common problems and solutions

5. Summary

The connection of PVC water pipes is a technical job and needs to be strictly followed. Only by choosing appropriate connection methods, using high-quality materials, and conducting follow-up inspections can the safety and stability of the pipeline system be ensured. I hope this article can provide you with a practical reference.
