预制保温管按保温层结构的划分
Prefabricated insulating pipes are divided according to the structure of insulating layer
常温聚氨酯直埋保温管、低温聚氨酯直埋保温管、深冷聚氨酯直埋保温管；
Normal temperature polyurethane direct buried insulation pipe, low temperature polyurethane direct buried insulation pipe, cryogenic polyurethane direct buried insulation pipe;
依照外护层的不同可以分爲：玻璃钢外护层聚氨酯直埋保温管、度聚乙烯外护层聚氨酯直埋保温管、钢外护层聚氨酯直埋保温管及其他外护层直埋保温管。
According to the difference of the outer protective layer, it can be divided into: FRP outer protective layer polyurethane direct-buried insulating pipe, degree polyethylene outer protective layer polyurethane direct-buried insulating pipe, steel outer protective layer polyurethane direct-buried insulating pipe and other external protective layer direct-buried insulating pipe.
依照保送介质的不同有很多种：如供水用的聚氨酯预制保温管、耐低温聚氨酯保温管，保送蒸汽用的蒸汽直埋聚氨酯复合预制保温管，石油上用的埋地硬质聚氨酯泡沫塑料防腐保温管等等。还有很多叫法如聚氨酯地埋管，聚氨酯预制管，聚氨酯直埋预制管，聚氨酯夹克管,聚氨酯发泡保温管等等。
According to the different delivery media, there are many kinds: polyurethane prefabricated insulation pipes for water supply, low temperature resistant polyurethane insulation pipes, steam-buried polyurethane composite prefabricated insulation pipes for steam delivery, buried rigid polyurethane foam plastic anti-corrosion insulation pipes for petroleum, and so on. There are many other names such as polyurethane buried pipe, polyurethane prefabricated pipe, polyurethane directly buried prefabricated pipe, polyurethane jacket pipe, polyurethane foamed insulation pipe and so on.
单一型：适用于150X2以下的供热介质，其中普通型适用于120C以下的供热介质，低温型适用于120~150~c的供热介质（引荐运用温度在140~2以下）。此类保温管的保温层由单一保温资料——聚氨酯硬质泡沫塑料构成，外护保温层维护壳。
Single type: suitable for heating medium below 150X2, of which the ordinary type is suitable for heating medium below 120C, and the low-temperature type is suitable for heating medium between 120 and 150 C (recommended operating temperature below 140 to 2). The thermal insulation layer of this kind of insulating pipe is composed of a single thermal insulation material, rigid polyurethane foam, and the outer thermal insulation layer maintains the shell.
复合型：适用于低温供热介质。此类保温管的保温层由两种保温资料复合而成。保温层、保温层的维护壳和经过热媒的任务钢管，它们不能结实地粘接在一同。内层爲新型耐低温保温资料，如离心玻璃棉毡、复合硅酸盐、玻璃泡沫，外层用聚氨酯硬质泡沫塑料停止复合制造。
Compound type: suitable for low temperature heating medium. The insulation layer of this kind of insulation pipe is composed of two kinds of insulation materials. Insulation layer, maintenance shell of insulation layer and task steel pipe through heat medium can not be bonded together firmly. The inner layer is a new type of low temperature and thermal insulation material, such as centrifugal glass wool felt, composite silicate and glass foam, and the outer layer is made of polyurethane rigid foam plastics.
度聚乙烯塑料（俗称夹克）维护壳。玻璃纤维加强不饱和聚酯树脂塑料（俗称玻璃钢）维护壳。采用其他资料的维护壳，如螺旋焊接钢管、直焊缝钢管、波纹管等。现场预制保温管：这种产品是爲了节省供热管道工程造价，在20世纪90年代应运而生的一种简易的直埋供热管道。钢管运送到施工现场停止发泡保温，保温后缠绕玻璃钢维护壳。
Degree polyethylene plastic (commonly known as jacket) maintenance shell. Glass fiber reinforced unsaturated polyester resin plastic (commonly known as FRP) maintenance shell. Maintenance shells with other data, such as spirally welded steel pipe, straight welded steel pipe, bellows, etc. Prefabricated insulating pipes on site: This product is to save the cost of heating pipelines, in the 1990s came into being as the times require a simple direct buried heating pipeline. The steel pipe is transported to the construction site to stop foaming and heat preservation, and winding the FRP maintenance shell after heat preservation.
