Due to the cold weather and the principle of thermal expansion and contraction, the welds and valves of the trachea are easy to freeze and crack, resulting in gas leakage.

Due to the principle of cold weather and expansion with heat and contraction with cold, the welds and valves of the trachea are prone to freeze cracking, and the measures that can be taken in case of gas leakage are as follows:

1. Adding insulation layer

Adding insulation layer to the trachea, welds and valves to reduce the influence of temperature change on metal parts. The insulation layer can be made of insulation materials such as asbestos and glass fiber, and can also be coated with insulation coating.

second, select high-quality materials

when manufacturing metal parts such as gas pipes, welds and valves, high-quality materials should be selected to improve their cold resistance and fatigue resistance. At the same time, the quality inspection and acceptance of materials should be carried out to ensure that they meet the requirements of relevant standards and specifications.

Third, control the gas velocity and pressure

In the process of gas flow, the velocity and pressure should be controlled to avoid excessive impact on the pipeline. The pipeline should be inspected and maintained regularly, and possible damages and defects should be found and repaired in time.

iv. installing safety accessories

install safety accessories, such as thermometers, pressure gauges, safety valves, etc. in the trachea, welds and valves, so as to find and eliminate possible hidden dangers in time. At the same time, the safety accessories should be inspected and maintained regularly to ensure their normal work and effectiveness.

safety of gas storage and application

1. storage and transportation conditions

due to the special properties of gas, its storage and transportation need to meet certain conditions. The storage temperature of gas should be kept within a reasonable range to avoid pressure fluctuation and potential gas leakage caused by temperature change. Gas storage containers and pipelines should be regularly pressure tested and integrity checked to ensure their structural integrity and sealing performance.

second, the application safety of gas

1. Safety operation procedures

When using gas, you should follow the safety operation procedures. Operators should receive relevant training to understand the nature, danger and emergency measures of gas. During use, the parameters such as gas pressure, temperature and flow rate, as well as the sealing performance of pipelines and equipment should be checked regularly. If there is any abnormality, measures should be taken immediately and reported.

2. Emergency treatment measures

In view of possible gas leakage accidents, emergency treatment measures should be formulated. These measures include, but are not limited to, quickly cutting off the gas source, starting the emergency discharge system, notifying relevant departments and personnel, and evacuating the site personnel. Emergency drills should be conducted regularly to improve the ability to deal with gas leakage accidents.
