The utility model relates to a constant temperature and thermal insulation tube heated by a marine live pipe pipe, including a carrier tube and a polyethylene pipe. The carrier tube is connected to a polyethylene tube in a coaxial line. A foam layer is provided between the carrier tube and the polyethylene pipe from the inside to the outside. There are a number of coaxial bracket groups between the carrier tube and the polyethylene pipe, and the coaxial bracket is three. More than three concentric brackets are set around the carrier pipe and are located between the carrier tube and the polyethylene pipe to make the delivery pipe and the polyethylene pipe coaxial. The two ends of the carrier pipe are connected with the flange, the flange is equipped with a insulated flange cover, and the inner end of the flange and the polyethylene pipe are fitted to the flange end of the foam layer. The inner end of the flange sleeve and the polyethylene pipe are connected with the heat shrinkable sleeve suit, and a copper heating pipe which is arranged along the length direction of the carrier tube, and a copper heating pipe is attached to the outer wall of the carrier tube or more than two copper heating pipes in the foam layer and connected to the carrier tube in the foam layer to fit the carrier pipe in the foam layer. The two ends of the red copper heating tube are worn through the sheath and penetrated through the flange end sleeve.

船用带电伴行管加热的恒温保温管
本技术涉及一种保温管,具体说是一种船用带电伴行管加热的恒温保温管。
技术介绍
船舶上输送液体或气体的管道,为了能保持管内气液温度,通常在运载管上套保温管或包裹岩棉、玻璃棉类保温材料,管道安装后装保温材料与运载管接触不紧密,存在隔热性能差、不便于安装等问题。现有专利号为CN00267078.X的预绝热管,其保温层由微孔硅酸钙和聚氨酯泡沫或聚氨酯泡沫组成,聚乙稀管套在运载管上,保温层制做在运载管与聚乙稀管之间,但其制作时由于微孔硅酸钙和聚氨酯泡沫或聚氨酯泡沫没有固定形状,套装聚乙烯管存在偏心问题导致圆周保温层厚度不均、管道连接端面不能有效保温,影响使用性能。
