The present low-temperature hot water floor radiation heating system adopts the heating way that the plastic heating pipe is built in the floor by using the hot water which is no more than 60 degrees as a heating medium. However, the connecting segment of the plastic pipe which extends from the ground and has a distance of one meter or so away from the water collector and the water separator is the defect of the plastic pipeline system. Firstly, the coefficient of linear expansion of the plastic pipeline is high, and the plastic pipeline is easy to be temperature distorted. Secondly, the plastic pipeline is not with rigidity, the low-temperature cold brittleness is high, and is easy to get deformed and damaged. Thirdly, the phenomenon of attrition is easy to happen when the plastic pipeline goes out or in the terrace, and a protection pipe has to be added. The effect of the external appearance of the formed exposed pipe is bad. The utility model is a connecting pipe of a pipeline which is a metallic plastic lined pipeline. The utility model is arranged among the water collector, the water separator, and the pipeline of the underground pipeline system. Therefore, the metallic plastic lined pipeline is not easy to get deformed or worn-out, and thus, the intensity of the heating pipeline of the low-temperature hot water floor radiation heating system is strengthened.
