The configuration, design conditions, process, inspection, manufacturing and acceptance of the stirred tank shall be in accordance with the relevant technical standards to achieve the heating, evaporation, cooling and low-speed mixing reaction functions required by the process. Pressure vessels must comply with GB150 {Steel Pressure Vessels} and atmospheric vessels must comply with NB/T47003.1-2009 {Steel Welded Atmospheric Vessels}. The pressure requirements in the reaction process also have different design requirements for the vessels. Jinchangtai Machinery Manufacturing Co., Ltd. processes, tests and runs in strict accordance with the corresponding standards. According to different production processes and operating conditions, the design structure and parameters of the stirring kettle are different, that is, the structural style of the stirring kettle is different, which belongs to non-standard container equipment.
