What are the solutions for high pressure in LNG cylinders?
2 Answers
Solutions for high pressure in LNG cylinders are as follows: 1. Maintenance: Do not expose the cylinder to high temperatures above 60 degrees Celsius for a long time. Especially for owners who place the cylinder in the truck bed and have installed an iron protective box, extra caution should be taken in summer to avoid exposing the vehicle to direct sunlight, avoid using it in high-static environments, prevent the cylinder from being impacted, and avoid contact with chemicals. 2. Daily inspection: Before starting the vehicle each time, the owner should inspect the cylinder. Particularly in winter when the vehicle is not used for a long time, the safety valve of the cylinder should be closed. The regular inspection cycle should not exceed 3 years. The first and second inspections for steel cylinders should be conducted every 3 years, and after the second inspection, inspections should be carried out every two years. For taxi steel cylinders, inspections should be conducted every two years, with the validity period of the second inspection being one year.
As an experienced driver operating LNG trucks, I've encountered high gas cylinder pressure issues several times. This is usually caused by hot weather or aging cylinder insulation, and must be addressed immediately to prevent explosions. Key solutions: First, park the vehicle in a shaded area to cool down, don't rush to open the valves; Then use professional tools to measure the pressure, if it's high, slowly release a small amount of gas to reach safe levels; Check valves and pipelines for leaks or blockages, replace components promptly if found; Also develop good habits, avoid prolonged exposure to sunlight, and maintain cylinder insulation regularly. Pay attention to the vehicle's overall condition - high pressure can affect the engine and gas supply system, which is particularly important during long-distance trips. Safe driving relies entirely on meticulous operation.
