The connection methods between them and pipe fittings are varied and each has its own characteristics. In this article, you will learn about the connection methods between pipes and hoses and pipe fittings, which will help you make better choices for your transmission system.

Connection Methods of Pipes and Pipe Fittings

There are several main ways to connect pipes and fittings, including glue bonding, socket connection, threaded connection and flange connection. The following is an analysis of the advantages and disadvantages of these connection methods and applicable scenarios.

Glue Bonding

Operation Method: Apply the corresponding glue on the outer surface of the pipe interface and the inner surface of the pipe fitting interface, quickly align the pipe with the pipe fitting and insert it. By rotating the two, the glue can be evenly distributed at the connection between the two, and after the glue solidifies, a firm and reliable connection is formed.

Advantages

  • Easy to Operate: Just apply the glue and rotate it to make it evenly distributed, and wait for it to solidify. It is very convenient to operate.

How to Choose the Appropriate Connection Method?

When choosing a connection method, you need to carefully consider the material type of the pipe or hose, the type of medium being transmitted, and the temperature and pressure of the transmission system. You need to choose the most appropriate connection method based on these specific information and data. 

For example, in a high-temperature and high-pressure system that transmits corrosive substances, you cannot use glue to bond pipes and pipe fittings. This is because it is easy to cause the glue to fail, the connection to break, and eventually leakage.

Conclusion

It is very important to choose the right connection method for pipes or hoses and fittings. When you make the right choice, you will save a lot of costs and get a solution that can ensure the long-term stability of your system transmission.
