Key Points of Anti-static Design for Pipeline Transportation of Methyl Methacrylate

pipeline transportation of methyl methacrylate (MMA) is a high-risk operation, because of its flammable and explosive characteristics, static electricity accumulation may lead to serious accidents. This article will discuss in detail the anti-static design points of pipeline transportation MMA to ensure the safety of the transportation process.

1. Electrostatic generation and harm

During pipeline transportation, MMA is prone to generate static electricity due to flow friction, pumping operations, or chemical reactions. If the static electricity is not released in time, it may cause electrostatic discharge (ESD), which may cause fire or explosion in flammable and explosive environment, resulting in serious accidents.

2. Material selection

Use conductive materials or electrostatic dissipative materials to make pipes, such as conductive plastic or coated steel pipes, to ensure that static electricity can be effectively discharged. Conductive seals shall be used at pipe connections to avoid static accumulation due to excessive contact resistance.

3. System grounding and bridging

Ensure that the piping system has a reliable grounding device to introduce static electricity into the ground. Pipe flanges, valves and other components shall be bridged to eliminate potential differences and prevent accidents caused by electrostatic discharge.

4. Electrostatic Monitoring and Control

Install online electrostatic monitoring equipment to monitor the electrostatic level in the pipeline in real time. Control the delivery flow rate and pressure to avoid excessive friction to generate static electricity. If necessary, antistatic agents can be added to reduce the risk of static electricity.

5. pipeline design parameter optimization

Optimize pipe diameter and length, control flow rate and temperature, reduce stirring and turbulence, and reduce the possibility of static electricity generation. Check and maintain the pipeline regularly to ensure its integrity and prevent static electricity accumulation due to leakage.

6. Operation and Maintenance

Strictly implement the operating procedures to ensure that the conveying system is well grounded. Regular maintenance of monitoring equipment, timely detection and treatment of electrostatic problems, to ensure the safety of the conveying process.

Summary

anti-static design of pipeline transportation of methyl methacrylate is a key link to ensure production safety. By selecting appropriate materials, optimizing design parameters, and implementing electrostatic monitoring and control measures, electrostatic hazards can be effectively prevented and safe production in the chemical industry can be ensured. Following relevant standards and specifications, combined with the technical support of a professional team, can minimize the risk of static electricity and ensure the smooth progress of the transportation process.
