As an important energy and chemical raw material, liquefied petroleum gas (LPG) plays an indispensable role in daily life and industrial production. The safety and efficiency of the filling and conveying process is directly related to the safety of people's lives and property and the normal operation of the enterprise. Therefore, the correct and safe use of liquefied petroleum gas filling and conveying equipment is essential. This paper will elaborate the use of liquefied petroleum gas filling and conveying equipment from four aspects: equipment selection, operation specification, daily maintenance and emergency treatment.

Selection and installation of 1. equipment

1.1 equipment selection

When selecting LPG filling and conveying equipment, factors such as production scale, process flow, and safety standards should be fully considered. Ensure that the selected equipment complies with national and industry-related safety regulations, with certificates and test reports. At the same time, the material of the equipment should be corrosion resistant, high pressure resistant, good sealing performance, in order to reduce the risk of leakage.

1.2 installation requirements

Equipment installation shall be carried out in strict accordance with the design drawings and manufacturer's instructions to ensure stable equipment foundation, reasonable pipeline layout and avoid cross interference. During the installation process, special attention should be paid to anti-static and lightning protection measures, as well as the improvement of ventilation and exhaust systems to ensure the safety of the operating environment.

2. Operation Specification

2.1 Operator training

All personnel involved in liquefied petroleum gas filling and conveying operations must undergo professional training, master equipment operating procedures, safety knowledge and emergency response skills, and hold corresponding induction certificates.

Inspection before 2.2 operation

Before each operation, the equipment should be fully checked, including the effectiveness of pressure gauges, thermometers, safety valves and other safety accessories, as well as the tightness of pipelines, valves and flange connections. The operation can be started after confirmation.

2.3 operation process

Preparation before filling: ensure that the pressure and temperature in the storage tank are appropriate, empty the residual gas in the pipeline, connect the filling hose and confirm the seal.

Filling operation: slowly open the filling valve, control the filling speed, avoid too fast flow rate caused by static electricity accumulation or pipeline vibration. At the same time, closely monitor the tank level and pressure changes to prevent overloading.

Closing and inspection: After filling is completed, close the valve in time, disconnect the filling hose, and check for signs of leakage around the equipment.

Routine maintenance of 3.

3.1 regular maintenance

According to the requirements of the equipment manual, regularly maintain the equipment, including replacing wear parts, cleaning filters, checking seals, etc., to ensure that the equipment is in good working condition.

3.2 safety accessory calibration

Safety accessories such as safety valves and pressure gauges shall be regularly sent to professional institutions for verification to ensure their accuracy and reliability. The calibration cycle shall comply with relevant national regulations.

3.3 leak detection

Use leak detection instruments to conduct regular leak detection of equipment and pipelines to detect and deal with potential safety hazards in a timely manner.
