[Haichuan New Energy] 12 towers for the Xinjiang Hesheng Silicon Industry project have entered the hoisting phase

Thread Content

Recently, with the successful closure of the vertical gap in the first-stage crude distillation tower, the 12 tower-type equipment units for Xinjiang Central Hesheng Silicon Industry Co., Ltd.’s 200,000 tons per year polysilicon production project, which were manufactured by Lanshi Heavy Equipment Mobile Factory Branch, have been completed on-site. The project has now entered the phase of equipment lifting and alignment of the vertical gaps. The first distillation column of Stage 1 has a diameter of 6,100 millimeters, a maximum wall thickness of 34 millimeters, and a height of over 100 meters. High requirements are placed on its verticality and alignment, making its assembly and installation quite challenging. The Hesheng Silicon Industry project team at Lanshi Heavy Equipment’s mobile factory maintained strict controls over safety and quality, organized production in a scientific manner, and strengthened coordination with construction and supervision units. Welding work was carried out continuously, from the initial lifting of the tower structure to its complete installation; this was accomplished 4 hours ahead of the timeline specified by the client. The assembly process was ultimately completed successfully, earning high praise from all the construction parties on site.
