On the afternoon of November 28th, Shijian Company used a 500-ton crawler crane main crane and an 80-ton crawler crane to walk the tail, after more than 3 hours of precise operation, the largest modularized Yantai Wanhua ethylene plant.
Pipeline - The cracked gas pipeline module was successfully hoisted into place, creating conditions for the full deployment of the cracking furnace process piping
.
The pyrolysis gas pipeline module of the project consists of one main pipeline and two branch pipelines.
The main pipeline has a diameter of 2 meters and a total length of 22 meters.
The branch pipeline has a diameter of 1.
8 meters and a total length of 25 meters.
The hoisting height is 28 meters and the weight is about 65 tons.
It is an ethylene plant.
The pipeline with the largest diameter is also the most critical pipeline of the cracked gas output quenching unit of the cracking furnace unit, and is the largest pipeline module in the entire ethylene project
.
The biggest difficulty of this cracked gas pipeline module is the asymmetric distribution of the two branch pipelines.
In addition, the pipe bracket and the thermal insulation are installed at the same time, and the overall center of gravity of the module needs to be calculated
.
