承压设备焊后热处理工艺实施的控制

Control of Post-welding Heat Treatment Process of Pressure Equipment

为了满足承压类特种设备安全技术规程对焊后热处理工艺的要求,确保焊后热处理工艺正确实施,需要从以下6个方面进行控制:焊后热处理设备,热处理温度测量、控制和记录各环节所用仪器,绝热材料的选用和铺设,焊后热处理的升温过程、保温过程和降温过程,对升温过程、保温过程和降温过程中可能出现的偏离提出相应纠偏措施,对所有热处理操作人员进行培训。

In order to meet the requirements of post-weld heat treatment process in the safety technical specification for special pressure equipment and ensure the correct implementation of post-weld heat treatment process, the following six aspects needed to be controlled: post-weld heat treatment equipment, instruments used for measuring, controlling and recording the heat treatment temperature, selection and laying of thermal insulation materials, heating process, heat preservation process and cooling process of post-weld heat treatment, heating process Corresponding corrective measures shall be put forward for possible deviation in the process of heat preservation and cooling, and all heat treatment operators shall be trained.
