WuGB/T3131—1998
This standard is formulated based on the start-up of domestic paddle dryers, the establishment of verification test equipment for dryers, the subsequent research on drying mechanism and the successful development of a series of products. The series specified in this standard have jacket volumes less than 450L. However, from the perspective of strength design, the paddle shaft and jacket components are subject to multiple loads. Therefore, in the requirements for material selection, inspection and testing, some clauses directly quote the provisions of GB150, while others directly put forward specific requirements.
This standard is proposed by China National Chemical Equipment Corporation. This standard is under the jurisdiction of the Chemical Machinery and Equipment Standardization Technical Committee of the Ministry of Chemical Industry. The drafting units of this standard are: Sanmenxia Chemical Machinery Factory, Chemical Machinery Research Institute of the Ministry of Chemical Industry. The main drafters of this standard are: Hao Jianlin, Xie Zhen, Yuan Fuxing, Sun Zhongxin, Xu Jianzhuang, Wang Yi. 1 Scope
