摘要： A pipeline is covered with a continuous wrapping sheet having heat-activatable adhesive on its inner side. The wrapping may be helically applied or may be heat shrunk to impart a circumferential stress conforming the wrapping tightly to the surface of the pipe. High frequency induction heating is applied to cause the adhesive to wet and bond to the pipe surface. The wrapping can be applied progressively and continuously along a pipeline excavated from the ground while the pipeline is in service. The product conveyed within the pipe assists in rapidly cooling the adhesive and wrapping sheet so that the pipe can be promptly relaid in the ground.
摘要翻译：管道上覆盖有在其内侧具有可热激活粘合剂的连续包装片。包裹物可以是螺旋应用的或可以被热收缩以赋予使包裹紧密地贴合在管表面上的周向应力。施加高频感应加热使粘合剂湿润并粘合到管表面。在管道投入使用的同时，可以沿着从地面挖掘的管道逐渐连续地施加包装。在管道内传送的产品有助于快速冷却粘合剂和包装片材，使得管道能够及时地被还原在地面上。

摘要： An easily removable coating or paint which is a formulation of acrylic acid polymers and a urethane polymer preferably two acrylic acid polymers are used, one with a relatively high acid number and hardness temperature (glass transition) (Tg) and the other with a lower acid number and hardness temperature (Tg). This removable paint is applied to a surface by roller, screen printing, spraying or brushing and can be removed by a remover which is basically an alkali material with a surfactant. The remover needs to be agitated and allowed to set for a few minutes and then washed away with water. Ammonium hydroxide with surfactant and acrylic thickeners in water is one remover. Another remover is a combination of more than one alkalis, solvent, surfactants and thickeners.
摘要翻译：使用作为丙烯酸聚合物和氨基甲酸酯聚合物的制剂的优选两种丙烯酸聚合物的容易移除的涂料或涂料，其具有相对较高的酸值和硬度温度（玻璃化转变）（Tg），另一种具有较低的酸数量和硬度温度（Tg）。该可除去的涂料通过辊子，丝网印刷，喷涂或刷涂施加到表面，并且可以通过基本上是具有表面活性剂的碱性材料的去除剂去除。需要将去除剂搅拌并放置几分钟，然后用水冲洗。氢氧化铵与表面活性剂和丙烯酸增稠剂在水中是一种去除剂。另一种去除剂是多种碱，溶剂，表面活性剂和增稠剂的组合。
