預(yù)制保溫管按保溫層結(jié)構(gòu)的劃分
Prefabricated insulating pipes are divided according to the structure of insulating layer
常溫聚氨酯直埋保溫管、低溫聚氨酯直埋保溫管、深冷聚氨酯直埋保溫管；
Normal temperature polyurethane direct buried insulation pipe, low temperature polyurethane direct buried insulation pipe, cryogenic polyurethane direct buried insulation pipe;
依照外護(hù)層的不同可以分爲(wèi)：玻璃鋼外護(hù)層聚氨酯直埋保溫管、度聚乙烯外護(hù)層聚氨酯直埋保溫管、鋼外護(hù)層聚氨酯直埋保溫管及其他外護(hù)層直埋保溫管。
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.
依照保送介質(zhì)的不同有很多種：如供水用的聚氨酯預(yù)制保溫管、耐低溫聚氨酯保溫管，保送蒸汽用的蒸汽直埋聚氨酯復(fù)合預(yù)制保溫管，石油上用的埋地硬質(zhì)聚氨酯泡沫塑料防腐保溫管等等。還有很多叫法如聚氨酯地埋管，聚氨酯預(yù)制管，聚氨酯直埋預(yù)制管，聚氨酯夾克管,聚氨酯發(fā)泡保溫管等等。
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.
單一型：適用于150X2以下的供熱介質(zhì)，其中普通型適用于120C以下的供熱介質(zhì)，低溫型適用于120~150~c的供熱介質(zhì)（引薦運(yùn)用溫度在140~2以下）。此類保溫管的保溫層由單一保溫資料——聚氨酯硬質(zhì)泡沫塑料構(gòu)成，外護(hù)保溫層維護(hù)殼。
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.
復(fù)合型：適用于低溫供熱介質(zhì)。此類保溫管的保溫層由兩種保溫資料復(fù)合而成。保溫層、保溫層的維護(hù)殼和經(jīng)過(guò)熱媒的任務(wù)鋼管，它們不能結(jié)實(shí)地粘接在一同。內(nèi)層爲(wèi)新型耐低溫保溫資料，如離心玻璃棉氈、復(fù)合硅酸鹽、玻璃泡沫，外層用聚氨酯硬質(zhì)泡沫塑料停止復(fù)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（俗稱夾克）維護(hù)殼。玻璃纖維加強(qiáng)不飽和聚酯樹(shù)脂塑料（俗稱玻璃鋼）維護(hù)殼。采用其他資料的維護(hù)殼，如螺旋焊接鋼管、直焊縫鋼管、波紋管等。現(xiàn)場(chǎng)預(yù)制保溫管：這種產(chǎn)品是爲(wèi)了節(jié)省供熱管道工程造價(jià)，在20世紀(jì)90年代應(yīng)運(yùn)而生的一種簡(jiǎn)易的直埋供熱管道。鋼管運(yùn)送到施工現(xiàn)場(chǎng)停止發(fā)泡保溫，保溫后纏繞玻璃鋼維護(hù)殼。
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.
