Design standard for fire and explosion protection of toluene transport tanker?

Toluene transport tanker fire and explosion design standards: to ensure chemical transport safety key factors

In the modern chemical industry, toluene as an important organic compound, because of its flammable and explosive characteristics, there is a high security risk in the process of transportation. Therefore, the fire and explosion-proof design of toluene transport tanker is particularly important. This paper will discuss in detail the design standards of fire and explosion-proof of toluene transport tanker from many aspects to ensure the safety and reliability of the transportation process.

1. Importance of Toluene Transport Tank Car Fire and Explosion-proof Design

Toluene is a highly volatile organic compound that is highly flammable and explosive. In the process of transportation, due to the complexity of the external environment and transportation conditions, the tanker may face a variety of risk factors such as high temperature, impact, and electrostatic accumulation. In the event of a fire or explosion, it will pose a serious threat to personnel and the environment. Therefore, the development and compliance of strict design standards is the basis for ensuring the safety of toluene transportation.

2. toluene transport tanker design standard requirements

1. Structural design standards

The design of the toluene transport tanker must comply with the relevant national and industry standards, such as GB 18565-2016 "Road transport of liquid dangerous goods tank vehicle design and manufacturing requirements". The tank structure of the tank car should be made of high-strength materials, and have good pressure resistance and impact resistance to prevent leakage or rupture caused by external forces during transportation.

2. Tank car accessories safety design

The attachment configuration of the toluene transport tanker is also critical. For example, the design of accessories such as level gauges, vents, and emergency shut-off valves should take full account of fire and explosion protection requirements. The vent should be equipped with a flame arrester to prevent external fire from entering the tank through the vent; the emergency shut-off valve should be able to close quickly in an emergency to avoid toluene leakage.

3. Pipeline system design

The piping system of the tank car shall be made of high-quality pressure-resistant and corrosion-resistant materials, and the sealing of the joints shall be ensured. All valves and flanged connections shall be rigorously tested to prevent leakage of toluene. The piping system shall be provided with a pressure relief valve to prevent the internal pressure of the tank from being too high.

3. material selection and anti-corrosion treatment

The material selection of toluene transport tanker directly affects its fire and explosion-proof performance. The tank body shall be made of high-quality stainless steel or aluminum alloy that meets the standard to ensure the strength and corrosion resistance of the material. The tank car surface should be anti-corrosion treatment, such as anti-rust paint or electroplating treatment, to extend the service life of the tank car and prevent leakage caused by corrosion.

4. safety accessories and monitoring systems

In order to further improve the fire and explosion-proof performance of the toluene transport tanker, the tanker should be equipped with a variety of safety accessories and monitoring systems. For example, the flame arrester can effectively prevent the flame from spreading through the vent; the bursting disc can quickly relieve pressure in an emergency to prevent the tank from rupturing. Tank car should also be installed temperature monitoring system, real-time monitoring of temperature changes in the tank, to prevent the temperature caused by high risk.

5. summary and prospect

The fire and explosion-proof design standard of toluene transport tanker is an important guarantee for the safety of chemical transportation. In the future, with the progress of science and technology and the continuous improvement of industry standards, the design and material selection of tank cars will pay more attention to fire and explosion-proof performance. Relevant enterprises should strengthen staff training, improve the safety awareness and emergency handling ability of operators, and ensure the safety and reliability of toluene transportation process.
