  目前国际上管道防腐层的主流发展趋势是对现有防腐结构(主要是3PE、DFBE)的持续改进,同时对施工工艺进行不断优化,补口技术的发展亦该顺应此趋势。例如,在材料改进方面,对热收缩材料热熔胶进行改性,在保证其粘结能力的前提下,增加其流动性以提升施工性能;对配套底漆进行改性,提升其对钢管防腐性能的同时强化与热收缩材料的粘结;对FBE表面进行改性制成粗糙防腐层,有效预防敷设、吊装、穿越等环节中发生损伤。另一方面,各种补口形式都在推进机械化施工,如移动式中频加热机、LPG催化燃烧红外补口加热机、环保型自动喷砂除锈设备、高压无气聚氨酯自动喷涂机等专用补口机具的研发、推广和应用将有利于减少人为不确定性对补口的影响,保证补口质量的稳定。
