China Construction machinery information

Guide: as of February 25, the machining workshop of Daqing Petrochemical Machinery Plant has successfully completed the processing of four pressure test rings for two evaporators and the processing of 4387 pipe heads. In order to ensure the normal operation of the company's production units and the production needs of LNG equipment in Wuhan, Hubei, Provides a strong guarantee. Facing the equipment manufacturing business

as of February 25, the machining workshop of Daqing Petrochemical Machinery Plant has successfully completed the processing of four pressure test rings of two evaporators and the processing of 4387 pipe heads, providing a strong guarantee for the normal operation of the company's production units and the production needs of LNG equipment in Wuhan, Hubei Province

in the face of new opportunities for the development of equipment manufacturing business, the petrochemical machinery plant has implemented a high-end, high-quality and efficient development strategy. In view of the bottleneck problems that have brought confidence to extruder enterprises, production efficiency and manufacturing quality, it has carried out process improvement research and application activities, and has established 18 process improvement topics in more than 30 projects reported, including heat exchanger manufacturing, welding method improvement, blanking process improvement New technology application and new product development

up to now, the petrochemical machinery plant has effectively improved 12 processes and promoted the refinement and strengthening of equipment manufacturing by increasing technological innovation and the transformation of tooling according to the overall dimensions of samples. Among them, the design and manufacture of fixed tanks for LNG storage and transportation equipment and the development and innovation of surface evaporative air coolers have been applied to manufacturing, which has improved production efficiency and product quality; After changing the saw welding process of stainless steel sheet when measuring hardness, the welding efficiency has been increased by times. It has been applied to the development project of LNG tanker (C2), tank container (C3) and fixed tank equipment. The longitudinal seam weld bead of 135 joint plates has been radiographic tested to be class I, meeting the requirements of the technical standard

moreover, in the process improvement project that has been concluded, the three achievements of in-situ stripping preparation of polymer/graphene composite heat pipe for improving the manufacturing quality of heat exchanger, such as cutting to length, derusting efficiency improvement of heat exchange pipe head, and manufacturing process improvement of spiral baffle heat exchanger, have been successfully applied to the manufacturing of heat exchanger equipment in Yulin coal chemical project of Shaanxi Zhongmei, Shandong Tai'an and Wuhan LNG equipment localization project of Hubei

at present, there are still six process improvements in petrochemical machinery plant, which are being carried out in an intense and orderly manner
