摘要
国内传统海底管道的铺设多采用手工补口,效率较低,而热收缩带补口施工质量会影响补口的长期可靠性。针对手工补口存在施工困难以及补口质量不稳定等问题,研究并引进新型机械化补口设备。通过实践经验表明,机械化补口设备能完成喷砂、预热、收缩、回火等工序的自动化操作,有效保证了热收缩带作为主涂层补口材料的安装质量,提高了补口效率,从而节省了大量的工程成本。
The traditional field joint coating （FJC） is applied by manual process, which shows low efficiency and affects the long-term reliability due to the unstable quality for heat shrinkable sleeve （HSS）. Since the manual FJC was unsatisfying, more advanced equipment emerged. The practice from project shows that the FJC installation machinery could accomplish the automation of blast cleaning, preheating, shrinking and post heating, which guarantees the quality of the HSS and reduces the cost of offshore installation.
