【Q&A Question 261】September 24, 2018: Briefly explain the purpose of conducting a leak test on hydrogenation units. After the unit is built or after maintenance, a leak test is carried out to check for any leaks at the flange connections of the equipment and pipelines. Additionally, during the process of starting up the unit, the entire system gradually experiences increases in temperature and pressure; especially in cases of high-temperature and high-pressure equipment, thermal expansion and contraction occur significantly, so leak tests must be conducted at each stage of pressure increase. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

Identify and address leaks in advance to prevent leaks while driving! Ensure successful driving
After the installation is completed or during maintenance, a gas-tightness test is required to check for any leaks at the flange connections of the equipment and pipelines. Additionally, as the system is brought online, its temperature and pressure increase gradually; especially in the case of high-temperature and high-pressure equipment, where thermal expansion and contraction are significant, gas-tightness tests must be conducted at each stage of pressure increase.
The purpose of airtightness testing is to verify the sealing performance of the system under operating pressure, reduce leaks during startup, and shorten the startup time. Happy Mid-Autumn Festival!
