摘　　要：热收缩带补口施工质量影响着补口的长期可靠性,针对手工补口存在施工困难、补口质量不稳定等问题,开发了机械化补口装备。实践经验表明,开发的机械化补口装备能完成喷砂、预热、收缩到回火等工序的机械化操作,有效保证了热收缩带作为3LPE补口材料的安装质量。Installation quality for heat shrinkable sleeve （HSS） affects the long-term reliability of field joint coating （FJC）. Since the manual FJC has the problems of difficult construction and unstable quality, FJC installation machinery was developed. The results from practice showed that the FJC installation machinery could accomplish the automation for blast cleaning, preheating, shrinking and post heating, which effectively guarantees the installation quality of the HSS as FJC material for 3LPE.
