Product Description:End Cap

I. End cap size standard

End cap is a common pipeline connectors, used to close the pipeline to prevent media leakage and prevent pollutants from entering the pipeline. Common end cap size standards are as follows:

1. Pipe diameter: this is the most basic end cap size standard, usually used to indicate the applicable pipe diameter range of the end cap. Common pipe diameters are DN15, DN20, DN25, etc., corresponding to different end cap sizes.

2. Inch size: in some countries or regions, end cap size standards usually use inch units. Commonly used inch size 1/2 inch, 3/4 inch, 1 inch and so on.

3. Nominal pressure: the nominal pressure of the end cap usually refers to the highest working pressure it can withstand. Common nominal pressure PN10, PN16, PN25, etc., corresponding to different end cap materials and applicable scenes.

Second, the end cap selection guide

Choosing the right end cap size is an important factor to ensure the normal operation of the pipeline. The following are some selection suggestions to help readers choose end caps more convenient:

1. Selection according to pipe diameter: this is the most common selection method, but it requires accurate measurement of pipe diameter. Usually, the size of the end cap should be the same as the pipe diameter.

2. Consider the applicable pressure: If the pipe is subjected to higher pressure, you need to select the appropriate nominal pressure. In general, the nominal pressure should be greater than the maximum working pressure of the pipeline.

3. Consider the characteristics of the medium: If the medium has a strong corrosive or high temperature, you need to choose the end cap material that can withstand these characteristics. Different end cap materials have different corrosion and temperature resistance.

4. Consider the use of the environment: If the end cap needs to be used indoors or outdoors, you need to consider its high temperature resistance, low temperature resistance, corrosion resistance and other properties.

C. Precautions

When selecting and using the end cap, you need to pay attention to the following points:

1. Do not exceed the maximum torque of the end cap: the end cap needs to control the size of the torque when installing, so as not to damage the pipeline or lead to leakage.

2. Use a suitable gasket: the material of the gasket should be the same as the applicable medium, which can effectively prevent leakage.

3. Regular inspection: End caps need to be inspected regularly to ensure their normal operation and prevent leakage.
