What factors affect the sealing of PE electrofusion fittings

As an important way to connect pipelines, the sealing of PE electrofusion pipe fittings directly affects the safe operation and use effect of the pipeline system. In the process of connecting PE electrofusion pipe fittings, sealing is a crucial indicator and is affected by many factors.
First, material selection is crucial. PE electrofusion pipe fittings are mainly made of polyethylene (PE) materials. Different types and grades of PE materials have different density, hardness, corrosion resistance and other properties, which directly affect the sealing performance. Selecting pipe fittings made of PE materials with good quality and stable performance can ensure the firmness and sealing of the connection.
Secondly, processing accuracy also has an important influence on sealing performance. When connecting, the ends of the pipe fittings and the pipeline must be kept flat and smooth, and the connection surface must be free of scratches, bumps and other defects, otherwise it will affect the sealing. Therefore, the level of processing accuracy directly determines the quality of the connection.
Connection pressure is another important factor affecting sealing. In the process of connecting PE electrofusion pipe fittings, applying appropriate pressure during connection can ensure that the connection surface of the pipe fittings and the pipeline is fully in contact, forming a uniform molten layer, and ensuring the firmness and sealing of the connection.
Control of the connection temperature is also crucial. When connecting, the ends of the pipe fittings and the pipe need to be heated to a certain temperature to melt and form an integrated connection. If the connection temperature is too high or too low, it will affect the formation of the molten layer, which will in turn affect the sealing performance.
In addition, the control of the connection time is also one of the key factors to ensure the sealing performance. The appropriate connection time can ensure the firmness and sealing of the connection. If the connection time is too short or too long, it will affect the sealing performance.
Finally, environmental conditions will also affect the sealing performance. Factors such as ambient temperature, humidity, and cleanliness during the connection process will affect the quality and sealing of the connection. Connecting in a dry and clean environment is conducive to ensuring the sealing of the connection.
