Pipe Flange Static Jumper: Principle, Function And Correct Operation Guide

Pipe flange static jumper is a measure to connect the pipe flange through metal wires to eliminate static electricity accumulation and ensure the safe operation of the pipeline system.

In the pipeline system, static electricity is a common physical phenomenon. Due to the flow and friction of the medium in the pipeline, static electricity may accumulate at the pipe flange. If it is not eliminated in time, it may cause dangerous situations such as fire and explosion. Therefore, the use of pipe flange static jumper technology is of great significance for preventing static electricity problems.

Principle of pipe flange static jumper

Pipe flange static jumper is to install metal wires between the pipe flanges to form an equipotential body between them, thereby eliminating static electricity accumulation. When the medium flows in the pipeline, the static charge generated by friction will be quickly transferred to the earth through the metal wire to avoid accumulation at the flange. In this way, even if there is static electricity in the pipeline, it will not pose a threat to the pipeline system.

Static jumper standard setting

1. Set the ground wire

Before connecting the pipe flange, the ground wire must be set. Under the condition that the grounding resistance is less than 1 ohm, a suitable location should be selected for reliable grounding. The ground wire must be connected to the electrostatic grounding device to ensure that the potential of the entire system is equal.

2. Electrostatic grounding

The electrostatic grounding of the pipe flange should meet the following requirements:

The electrostatic grounding resistance should be less than 10 ohms;

The pipe flange and the electrostatic grounding body are connected by copper wire;

The electrostatic jumper line should be directly connected to the earth, and the grounding wire should be well laid to ensure safety and reliability;

The electrostatic jumper line should be parallel to the pipeline and no more than 10 meters away from the pipeline;

When setting up the electrostatic jumper, avoid using the same grounding line as other electrical systems to ensure electrostatic safety.

3. Detect the effectiveness of the electrostatic jumper

After completing the electrostatic jumper, it is necessary to test to ensure the effectiveness of the jumper. The method is to use a multimeter to test the test point. If the resistance is less than 10 ohms, it means that the electrostatic jumper line is effective.

Implementation steps of electrostatic jumper

1. Determine the jumper point

Select appropriate jumper points on both sides of the flange connection to ensure that the jumper wire can be firmly connected.

2. Choose the right jumper wire

The jumper wire should have good electrical conductivity, and corrosion resistance and wear resistance should be considered.

3. Perform the jumper operation

Connect the two ends of the jumper wire to the selected jumper points to ensure that the connection is firm and reliable.

4. Inspection and testing

After completing the jumper, necessary inspections and tests are required to ensure that the jumper effect is good and there is no potential difference.

The role of static jumper on pipe flange

1. Prevent fire and explosion

Static jumper can eliminate static electricity accumulation at the pipe flange and reduce the risk of fire and explosion.

2. Protect equipment

Static jumper can reduce the damage of static electricity to pipeline system equipment and extend the service life of equipment.

3. Improve work efficiency

By eliminating static electricity problems, the pipeline system can be ensured to operate stably and work efficiency can be improved.

How to correctly perform static jumper on flange

1. First, you need to select the right tools and grounding wire materials.

2. Select the flange position and remove the surface dirt on the flange.

3. Use tools to remove the protective elements on the flange to expose the metal surface.

4. Connect the grounding wire port to the flange.

5. Connect the grounding wire at the other end to the ground or grounding rod.

6. Tighten the flange gently by hand to tightly combine the flange and the grounding wire.

Summary

In short, the static jumper of the pipe flange is an important measure to ensure the safe and stable operation of the pipeline system. By understanding its principles and functions and taking correct operating guidelines and precautions, static electricity problems can be effectively prevented and solved, providing strong guarantees for the safe operation of the pipeline system. In practical applications, a reliable flange supplier, suitable metal wire, installation method and maintenance cycle should be selected according to the specific situation to ensure the effectiveness and reliability of the static jumper facilities.
