Flame arrester low pressure deflagration

The flame arrester is a device used to prevent the flame from spreading through the pipeline or equipment, which is widely used in flammable and explosive places such as petroleum, chemical industry and natural gas. According to the different use scenarios and pressure ranges, the flame arrester can be divided into a variety of types, of which the low pressure deflagration arrester is especially suitable for operating the pressure close to the normal pressure level of the system.

Cause of low pressure deflagration of flame arrester

Expiration of life: the flame arrester has a certain service life, and after a long time of use, its internal components may age, resulting in reduced performance.Pipeline Flame Arrester for tanks If the aging flame arrester continues to be used, it may cause deflagration.

Mechanical damage: In the daily use and storage process, the flame arrester may be subjected to mechanical damage such as falling, squeezing, collision, resulting in damage to the seal, resulting in uncontrolled pressure and deflagging.

High temperature environment: In a high temperature environment, the pressure of the flame arrester may gradually rise, resulting in an increase in temperature.Flame Arrester If exposed to the sun for a long time or stored in a high temperature environment, the pressure relief plug of the flame arrester may burst due to excessive pressure, or the pressure relief pump may overheat and cause the flame arrester to explode.

Improper design or installation: The design or installation of the flame arrester does not meet the requirements, such as unreasonable design of the fire resistance layer, improper installation position, etc., may also lead to deflagration at low pressure.

Xuanzong liked it very much, mainly because he was fascinated by the colorful jade. So he sent for the royal Treasury to search for objects made of five-colored jade. The royal family had its own storehouse to store treasures. The Tang Dynasty was the center of the world at that time, and many countries traveled thousands of miles to offer treasures, so the collection was very large. In addition, at the beginning of the Tang Dynasty, Taizong Li Shimin used imperial edicts to seek antiques and treasures scattered among the people since the Wei and Jin Dynasties. The calligraphy works of Wang Xizhi in the Eastern Jin Dynasty alone collected "thousands of papers", including the famous "Lanting Collection Preface". In the imperial house of the Tang Dynasty, there were many old things in the Sui room of the previous dynasty, some were liked by the emperor, and some were hated: "There is a jade ape with crossed arms in the inner library, and the two arms are intersected like a chain. He rode with his courtiers, hated their decorations, and crushed them with his whip." Also, "Ruizong tasted the library, and saw a whip, golden, four feet long, several sections with insects biting, like a disc dragon, hanging on the target, like ear skin, or Yan Sui Palace library old things also." The former, Li Shimin did not like the jade monkey's adornment, with a whip to break it;
