工艺流程
涂覆说明
1、   喷涂方法:主要采用静电喷涂和热喷涂,也可采用流化床喷涂
2、   除油、干燥:一般采用灼烧管道表面,以除去油污及水分等
3、   抛丸或喷砂:表面处理质量应达到Sa2 1/2级,锚纹深度应在 40~ 100 um 范围内,处理后应清理干净并在8h内进行喷涂。
4、   预热:采用中频感应加热方式,应用于单层FBE时,温度应控制在210~ 250℃;应用于3PE时,温度控制在180-200℃。(注意:钢管加热温度不得超过260℃。)
5、   检漏:单层FBE,利用电火花检漏仪在涂膜温度低于100℃状态下,对每根管的全部涂层做漏点检测,电压为5V/um;检漏3PE时,电压为25KV。
