Shijian Zhongke's ethylene "leading" steam cracker construction progresses steadily

The 800,000-ton/year ethylene steam cracking unit of Zhongke Refinery and Chemical Integration Project was installed and started on August 20 last ye.

The "faucet" device is divided into six blocks: cracking furnace, quenching, compression, cold zone, hot zone, and low temperature ta.

Strive to build underground pipes

On August 20, 2018, the installation of the underground pipes of the steam cracking unit beg.

The ten construction plans are carefully arranged and implemented in strict accordance with the "labor competition" control pl.

Especially in the installation of a thick underground pipeline with a length of 360 meters and a diameter of 2 meters, a wide underground pipe trench with a length of 200 meters, a width of 22 meters at the top, a width of 11 meters and a depth of 4 meters was excavated, and two thick pipelines can be plac.

By August 31, the installation of underground pipes was 93% complete, and the first-time welding pass rate was 94

Second, the module installation tree image

From the end of November last year to the end of April this year, under the careful organization and implementation of the contractors of the engineering construction company, after 5 months of hard work by the tenth construction company to install and transport the company's large-scale hoisting and construction of soldiers, 18 large towers of the steam cracking unit were installed in April this ye.

The total weight of these 18 towers is more than 7,000 to.

In 5 months, more than 600 installation and hoisting workers set off a climax of modular construction "labor competition" in the steam cracking unit ar.

•, create conditions on the structure

The total amount of steel structure installed in the steam cracking plant is 13,124 to.

Fourth, force tailor-made pipe welding

The total number of welding process pipelines of the steam cracking unit is 896,561 inches in diamet.

Shijian Company held several promotion meetings and human resources docking and coordination meetings, and decided to adopt the organizational model of "overhaul and transformation" to gather the strength of the company to build the Zhongke project, especially the tough battle for the pipeline installation of the "leading" steam crack.

        Shijian fully opened the pipeline processing plant in Zhongke for pipeline prefabricati.

        Each block will send a special person to plan on a daily basis to compare and assess the pipeline welding dynamics of each construction team and te.

        As of August 31, the cumulative welding of pipeline prefabrication of the device was 307,792 inches, accounting for 35% of the total pipeline weldi.

        It is understood that the pipeline installation of Shijian in the steam cracking unit is in full swi.
