Dalian Petrochemical Co., Ltd. 10 Million Tons of Atmospheric and Vacuum Distillation Plant

On March 28th, China's largest combined annual atmospheric and vacuum distillation unit with a capacity of 10 million tons was successfully driven by Dalian Petrochemical Company once and produced qualified products. This enabled Dalian Petrochemical to reach a capacity of 20,500,000 tons per year, indicating that PetroChina has The largest refinery base in China.
The 10 million tons atmospheric-vacuum distillation combined unit is the leading device for Dalian Petrochemical Corporation's processing of Russian crude oil technological transformation projects. It is currently the largest single distillation unit in China, and is also a key project for China's oil refining business “10th Five-year Plan” restructuring. One of the landmark projects. This set of equipment introduces international advanced design concepts for process integration and optimization. It integrates with other devices on light hydrocarbon recovery production units, and uses advanced international technologies such as decompression deep drawing and heating furnace auto-ignition for the first time in China. High in content and difficult to build.
This set was placed on groundbreaking on February 22, 2005. It was completed on November 18, 2005 and realized China Communications. At the same time, it completed the construction of related system supporting projects. The device entered the construction process on March 15 this year.

These fittings are used in lines that might require a quick-disconnect system. They are also used to
facilitate lining up the bolt holes of flanges when there flanges are now welded or fastened to the pipe.
Normally, stub ends are installed in pairs, the paired fittings mating with two lap joint flanges. This allows wasy opening of the line for future cleaning and inspection and if the line requires replacement, the flanges can be reused because they are not fastened to the system. They ride freely in the outside of the pipe. Lap joint stub ends are made with serrated gasket surfaces for improved sealing of the connection and prevention of leakage at the joint. This surface has replaced the raised gasket surface of a flange.
