PVC (polyvinyl chloride) pipes are a common plastic pipe material, widely used in water supply and drainage, sewage, communications, electricity, gas, and other fields. There are many ways to connect PVC pipes, and different connection methods have their own characteristics and scope of application. The following is a detailed introduction to several How to connect PVC pipe methods.
How to connect PVC pipe?
1. Bonding: Bonding is the way to connect PVC pipe and pipe fittings through adhesive. This method is easy to operate and firmly connected and is suitable for PVC pipes and fittings of various specifications and shapes. When bonding, the surface of the pipe and pipe fittings should be clean and dry, and the adhesive should be evenly applied to ensure the bonding quality.
2. Socket connection: Socket connection is to insert one end of the PVC pipe into the socket of the pipe fitting, and realize the connection through the friction between the socket and the socket. This connection method is simple and fast and is suitable for PVC pipes with small diameters. However, the sealing performance of the socket connection is relatively poor, which may cause leakage, so it is necessary to ensure the tightness of the socket and the socket.
3. Elastic rubber sealing ring connection: Elastic rubber sealing ring connection is realized by installing a rubber sealing ring at the connection part of the PVC pipe and pipe fitting. This connection has good sealing performance and is suitable for pipeline systems with high sealing requirements. When installing, ensure that the specification of the rubber sealing ring matches the pipe and is correctly installed in the connection part.
4. Threaded connection: Threaded connection is achieved by tightening the thread parts of the PVC pipe and pipe fittings together. This connection method is firm and reliable, and is suitable for PVC pipe with large diameter and thick pipe wall. The integrity and accuracy of the thread should be ensured when threading, and the appropriate thread lubricant should be selected to ensure the quality of the connection.
5. Flange connection: Flange connection is through the PVC pipe and flange welded or glued together, and then connected with other equipment in the pipeline system, valves, etc., through the flange. This connection method is suitable for equipment, valves, and other parts in the pipeline system that need frequent maintenance and replacement. When connecting flanges, ensure the flatness and concentricity of the flanges to ensure the connection is firm.
Advantages of PVC pipes
1. Light weight: PVC pipes are light in weight, which can greatly reduce transportation costs and installation construction intensity.
2. No harm to water quality: The raw materials of PVC pipes are composed of carbon and hydrogen, and no toxic heavy metal salt stabilizers are added. It has good hygienic properties and is suitable as a tap water piping material.
3. Good heat resistance: PVC pipes remain stable when the working water temperature is 70 degrees, and the softening temperature reaches 140 degrees, with good heat resistance.
4. High mechanical strength: PVC pipes have high impact resistance, external pressure resistance and water pressure resistance, and are suitable for various standards.
5. Long service life: Underrated application temperature and pressure, the service life of PVC pipes can reach more than 50 years, and it has the function of blocking ultraviolet rays and radiation protection so that the product will never fade.
6. Good corrosion resistance: PVC pipes can withstand the corrosion of various chemical media, have good acid resistance, alkali resistance, and corrosion resistance, are not easy to rust, not easy to breed bacteria, have no electrochemical corrosion, and are suitable for the chemical industry.
