鉴于导轨、体座组焊坡口及相邻区域、定位凸台的结构及尺寸，无法严格按照R

In view of the structure and size of guide rails, body seat assembly welding grooves and adjacent areas, and positioning bosses, it is impossible to carry out magnetic particle inspection in strict accordance with the requirements of RCC-M MC5000. Moreover, the use of electromagnetization method will inevitably cause more serious spark damage to the machined surface. <br>Therefore, we believe that: <br>1. It is unreasonable to only allow the flux magnetization method. We suggest to allow the flux magnetization method. <br>2. Except for the machined parts of the valve body end, we think that the use of PT for other machined parts is also applicable. It is recommended that other machined parts also allow the use of PT inspection methods

In view of the structure and size of assembly welding groove, adjacent area and positioning boss of guide rail and body base, magnetic particle inspection by electromagnetic method cannot be carried out in strict accordance with the requirements of RCC-M mc5000. Moreover, the electromagnetic method inevitably causes serious ignition damage to the machined surface.<br>Therefore, we believe that:<br>1； It is unreasonable to only allow the use of through electromagnetic method. We suggest that the use of through magnetic magnetization method is allowed<br>2. In addition to the machined parts at the end of the valve body, we believe that PT is also applicable for other machined parts, and we suggest that PT detection method is also allowed for other machined parts<br>

In view of the structure and size of guide rail, body seat assembly welding groove, adjacent area and positioning boss, it is impossible to carry out magnetic particle inspection by electrified magnetization method in strict accordance with RCC-M MC5000. Moreover, the electrified magnetization method inevitably causes serious ignition damage to the machined surface. Therefore, we believe: 1； It is unreasonable to allow only the energization magnetization method. We suggest that the energization magnetization method be allowed. 2. Apart from the machined parts at the end of the valve body, we think that it is also applicable to use PT for other machined parts, and we suggest that other machined parts are also allowed to use PT detection method.
