Propylene rectifying tower, the heaviest equipment in ethylene project

On February 24, the propylene rectifying tower, the heaviest and heaviest ethylene plant in one million tons / year ethylene plant of Yantai Wanhua polyurethane industrial chain integrated ethylene project undertaken by Shijian Construction Group Co., Ltd., was successfully hoisted in place, marking that the ethylene plant equipment installation of the project entered the "fast lane". The diameter of the column is 8.5m, the wall thickness is 54mm, the height is 114.3m, the weight of the equipment body is 1460t, and the total lifting weight is 1970 tons. The tower is not only the highest and heaviest equipment in the 1 million T / a ethylene plant, but also one of the key lines in the construction of the whole ethylene plant. The 10th Construction Company attached great importance to the hoisting of large-scale equipment, strengthened the close cooperation with various cooperation units, planned in advance and organized scientifically before the propylene rectifying tower entered the site, and put all efforts into the prefabrication of equipment attached tower platform and process pipeline.

After the equipment is transported to the designated position on the construction site, the project Department of the tenth construction of the people's Republic of China mobilizes professional construction forces such as riveters, plumbers, cranes and welders to work overtime, light up the lights and fight at night, and organizes a battle of "wearing clothes and hats". Especially when the Spring Festival comes, the leaders of the project department unite and lead the party members and cadres to command, solve the problems on the site at the first time, and on the one hand, stabilize the ideology of the staff On the one hand, we took the lead in demonstration and did a good job in logistics. In the first 20 days of this year, we successfully completed the construction tasks such as the installation of the 20 storey attached tower platform and the welding of the 970 inch diameter process pipeline. In the last 10 days of this year, we improved the equipment insulation work. After this year, we stepped up to improve the construction tasks such as the 700 meter conduit and 110 lamps. The modular construction has a considerable depth The installation target that the tower light is on is realized, which creates favorable conditions for subsequent hoisting work. The 4000 ton crawler crane, the largest in China, is used for the hoisting of propylene rectification tower, and the 1000 ton crawler crane is used for the hoisting. Through the joint efforts of all participants in the tenth construction, the hoisting task was finally completed safely, with high quality and efficiency, which was highly praised by the owner, the supervisor and other participants.
