Description

Technical Field

[0001] The utility model relates to the field of styrene pipelines, in particular to an anti-polymerization styrene pipeline. Background Technique

[0002] A styrene pipeline is a pipeline system specifically used for transporting styrene or other related chemicals. It adopts special materials and designs to ensure the stability and safety of styrene during transportation. The styrene pipeline has good corrosion resistance and can resist the erosion of chemicals such as styrene. At the same time, it also has excellent sealing and connection performance, which can effectively prevent leakage and pollution. In addition, the styrene pipeline also has high strength and durability, and can operate stably for a long time to meet the needs of industrial production.

[0003] For traditional styrene pipelines, such as the pipeline from the shell side outlet of TT-1239 to the inlet of GF-1242S, due to the overly long pipeline length and no fluid flow for a long time, polymer accumulation occurs inside the pipeline, which in turn leads to blockage problems. This not only affects the normal operation of the production line, but may also cause damage to the equipment and even threaten production safety. Content of the Utility Model
