Description

Technical Field

[0001] This utility model relates to the field of safety protection equipment technology, specifically to a convenient safety railing. Background Technology

[0002] Oil and gas storage and transportation companies typically set up large-scale storage tanks in storage areas to store oil products for oil and gas storage operations. The oil products generally include crude oil and refined oil. At the same time, in order to facilitate oil and gas transportation operations, the storage tanks are often located in coastal areas to facilitate long-distance shipping by ships.

[0003] Due to the constant influence of monsoons in coastal areas, the air is highly humid and saline, causing significant corrosion to equipment. The safety railings around the top of storage tanks are particularly vulnerable to this corrosion, which poses a constant risk of breakage and collapse, severely impacting the safe operation of the storage area. Repairing safety railings typically requires hot work such as welding. However, due to the flammable and explosive nature of oil storage, hot work necessitates emptying and thoroughly cleaning the tanks before hot work can commence. This process is generally lengthy, leaving tanks with corroded safety railings unprotected for extended periods, increasing the risk to personnel and ultimately affecting the normal operation of the storage area.

[0004] In view of the above-mentioned defects, the creator of this utility model has finally obtained this utility model after a long period of research and practice. Summary of the Invention
