Description

Technical Field

[0001] The utility model relates to the technical field related to pipeline transportation, in particular to a safety cover for a chemical pipeline. Background Art

[0002] In chemical production, many chemical raw materials will produce toxic gases during preparation. For example, if ore contains sulfur, sulfur-containing gas will be produced during the extraction process. Usually, sulfur-containing gas is toxic gas, and many toxic gases are easily soluble in water. This makes it difficult to separate the toxic gas at the source. The only way is to transport this part of the solution containing toxic gas through pipelines.

[0003] Since pipelines need to be connected in multiple sections to form a complete transportation channel, leakage is very likely to occur in the connecting parts. Once leaked, toxic gases will accumulate around the connecting parts, which can easily affect the health of workers. Utility Model Content
