尿素装置中压分解器分布管制造工艺

Manufacturing Process of the Medium Pressure Distributor of Urea Plant

结合生产实际,总结了尿素装置中压分解器制造工艺过程,重点介绍了切向开孔、配合端面加工等关键工序控制措施,提出使用工装,保证切向开孔的同尺寸、同高度、同精度,采用预装来检验配合端面互换性,对今后类似结构设备制造提供了参考与借鉴。

Based on the actual production,this paper summarizes the manufacturing process of the urea mid pressure decomposer,with the focuses on the tangential opening,fitting end processing and other key process control measures. It also suggests the use of tooling to ensure the cut to the same size,height and precision hole and the adoption of preload to test the interchangeability of the fitting ends. This research provides a reference for manufacturing the equipment with the similar structure in the future.
