China Petrochemical News Network News Recently, the Maoming styrene project crude cracking gas plant undertaken by the Fifth Construction Company of the Refining and Chemical Engineering Group, the first set of cracking furnaces weighing 48.
6 tons in the last section of the chimney was hoisted in place as a whole, and the cracking furnace has achieved the goal of installing important nodes.
.
The cracking furnace is designed for a single unit of 80,000 tons per year, the main body elevation is 44.
4 meters, the highest elevation including the chimney frame is 60.
3 meters, the total weight of the external steel structure frame and platform is about 710 tons, and the total weight of the equipment is about 259 tons
.
The construction has the characteristics of large furnace body weight, complicated steel structure connection space, high safety risk and high quality requirements
The cracking furnace has a total of more than 55,000-inch diameter process pipeline installation works, including a variety of materials and high-pressure pipelines, and currently 10,000-inch diameter has been prefabricated and installed
.
In order to ensure the smooth progress of pipeline installation, the project department strictly compiles welding operation instructions, establishes a ledger for special welding consumables and welds, arranges special personnel to update the database in time, track the results of non-destructive testing and repair the welds
