Yangzi Petrochemical “three defenses” security device stability summer

In the summer season, Yangzi Petrochemical Company extensively carried out “leakage prevention, flood control, and lightning protection” in order to ensure the stability of the installation. It also performed various operations safety supervision and maintenance of operating equipment.
Summer heat is a test for the safe and stable production of petrochemical companies. Due to the thermal expansion of gas, some pipelines and equipment can easily leak at high temperatures, causing explosions and other accidents. At the same time, heavy rainfall and thunderstorms in summer have also threatened petrochemical production. To this end, Yangzi Petrochemical has taken stringent safety measures in various aspects: Before entering the summer, some pipelines and large-scale equipment were inspected, and the leakage points were handled. The project that was included in the hidden danger management plan was implemented swiftly to prevent the production process. The hydrogen gas, nitrogen gas, and liquefied gas leaked in a continuous high-temperature environment; after the summer, the monitoring of possible leaks was intensified. In particular, regular inspections of high, remote, and dangerous spots on the pipe gallery revealed signs of leakage. Timely notification and rectification; timely adoption of clean water and sewage diversion measures to prevent pollution caused by the entrainment of large amounts of wastewater in the plant area; to strengthen the inspection of grounding points for lightning protection to ensure the safety of the device; and to conduct regular inspections of electrical equipment to avoid The conditions of grounding, discharging, and tripping of electrical equipment and electrical switches that are prone to occur in the summer with heavy air humidity ensure the safe operation of production.
