  2.1 防腐热缩带或缠绕带的质量检验补口外观应逐个检查,防腐热缩带或缠绕带表面应光滑平整 无皱折 无气泡.两端坡角处与热缩套 贴合紧密.无空隙.表面没有碳化现象。热缩带周向应有热熔胶粘剂均匀溢出。补口处应用火花检漏仪逐个进行针孔检查.检漏电压15Kv。如出现针孔.应重新补口。防腐热缩带的粘接力应符合要求.在管体温度25左右5度时的剥离强度应不小于50N/cm
  2.2 防腐涂料(底漆)的质量检验
  防腐涂料 (底漆)的质量主要是漏点检测,在涂层完全固化且冷却至环境温度下.对每个补口进行检测。用火花检测仪器.检测电压:普通级2Kv,加强级2.5Kv,测试头在接触涂层时.以大约0.2m/s的速度移动。
