保溫建材在市面上的品種越來越多，其中聚氨酯資料的保溫產(chǎn)品就夠消費(fèi)者看上一段時(shí)間的，普通的消費(fèi)者在選購時(shí)對(duì)價(jià)錢還是很關(guān)懷的，那么我就先來看看聚氨酯直埋保溫管的市場價(jià)錢。綜合整體市場開展趨向思索，依據(jù)聚氨酯直埋保溫管的開展形勢來看，直埋保溫管的價(jià)錢相比前段時(shí)間有了很大幅度的降低，關(guān)于消費(fèi)者來說無疑是個(gè)好音訊。價(jià)錢要素肯定了，我們就來看看重要的一局部，技術(shù)參數(shù)，聚氨酯直埋保溫管是如何供熱的。
There are more and more kinds of thermal insulation building materials on the market. Thermal insulation products of polyurethane materials are enough for consumers to see for a period of time. Ordinary consumers are very concerned about the price when choosing and purchasing. Then I will first look at the market price of polyurethane direct-buried thermal insulation tubes. Considering the overall market trend, according to the development situation of polyurethane direct-buried insulating pipe, the price of direct-buried insulating pipe has been greatly reduced compared with the previous period, which is undoubtedly a good news for consumers. The price factor is affirmed. Let's look at an important part, technical parameters, and how polyurethane direct-buried insulating pipes heat supply.
采暖埋地直埋聚氨酯保溫依然以相當(dāng)快的速度開展著。下面呢就讓我們一同分享一下聚氨酯保溫管的新資訊 ，給大家說一下人們都相比照較關(guān)懷的“聚氨酯保溫管資料的價(jià)錢”?？傮w來說呢隨著聚氨酯保溫管的開展速度之快和一些新興企業(yè)的增加，使得聚氨酯保溫管的價(jià)錢比之前有了很大的下調(diào)。當(dāng)然也要看詳細(xì)是哪一種直埋管而定。
The thermal insulation of buried polyurethane is still developing at a fairly fast speed. Now let's share some new information about polyurethane insulating pipes. First of all, let's talk about the price of polyurethane insulating pipes that people care about. Generally speaking, with the rapid development of polyurethane insulation pipes and the increase of some new enterprises, the price of polyurethane insulation pipes has been greatly reduced. Of course, it also depends on which kind of buried pipe is in detail.
應(yīng)用范圍也是越來越普遍，更由于其施工煩瑣，防腐效果顯著而被大量地用于各種供熱，制冷、輸油、輸氣等各種管道。防聚氨酯發(fā)泡保溫管道規(guī)范-檢測水、防腐、耐老化：由于聚氨酯泡沫的閉孔率可到達(dá)92%以上，用聚氨酯泡沫作為直埋管道的保溫層，不只能夠起到保溫隔熱的作用，而且能有效地避免水、濕氣以及其它種種腐蝕性液，氣體的滲透，避免微生物的滋生和開展。順應(yīng)性強(qiáng)：聚氨酯泡沫與各種材不停止結(jié)實(shí)的粘合，因而，作為直埋管的保溫層簡直無需思索防層與之粘合的問題。
The scope of application is also becoming more and more widespread, but also because of its cumbersome construction, energy-saving and anti-corrosion effect is remarkable, it has been widely used in various heating, refrigeration, oil and gas pipelines. Specification for polyurethane foam insulated pipes - water, anticorrosive and aging resistant: as polyurethane foam has a closed porosity of more than 92%, polyurethane foam is used as a thermal insulation layer of directly buried pipes, not only to play a role of thermal insulation, but also to effectively avoid water, moisture and other corrosive liquids, gas infiltration. Through, avoid the breeding and development of microorganisms. Strong adaptability: polyurethane foam and all kinds of wood do not stop adhesion. Therefore, as a direct buried pipe insulation layer, there is no need to think about the problem of preventing the adhesion between layers.
聚氨酯保溫層的順應(yīng)溫度-196℃，短時(shí)(十幾小時(shí))可達(dá)196℃，假如用戶需長期溫度190度，我們可依據(jù)用戶需求用高溫料成型。直埋式預(yù)制保溫管(管中管) 直埋式保溫管由保送介的鋼管，高密度外套管，以及鋼管和外套管之間的填充的聚氨酯硬泡保溫嚴(yán)密分離而成。聚氨酯保溫管鋼套鋼直埋保溫管的耐高溫性能其它外維護(hù)管都不能與之想媲美。為了保證的公開水位高且又想讓公開水不影聚氨酯發(fā)泡保溫管規(guī)范-檢測響蒸汽直埋管道的正常運(yùn)轉(zhuǎn)，外維護(hù)層采用嚴(yán)密、鞏固的鋼管外殼。
The compliance temperature of polyurethane insulation layer is - 196 C, and it can reach 196 C in a short time (more than ten hours). If the user needs 190 C for a long time, we can use high temperature material to shape according to the user's needs. The direct-buried prefabricated insulating pipe (in-pipe) is made of the steel pipe for delivery, the high-density outer sleeve, and the rigid polyurethane foam filled between the steel pipe and the outer sleeve. The high temperature resistance of polyurethane insulating pipe with steel sleeve and directly buried insulating pipe is not comparable to that of other external maintenance pipes. In order to ensure that the open water level is high and that the open water can not be shaded by the polyurethane foamed insulation pipe specification - testing the normal operation of the direct buried pipeline with sound steam, the outer maintenance layer adopts a tight and consolidated steel tube shell.
防腐層：是為了延長鋼管的使壽命，維護(hù)外鋼管防止腐蝕物會(huì)腐蝕到鋼管。外護(hù)鋼管：為了保證直埋保溫管的正常運(yùn)轉(zhuǎn)，維護(hù)保溫層免受公開水的腐蝕，支撐工作管并能夠接受一定的外部荷載。鋼套鋼直埋保溫管聚氨酯泡沫層：目的是保證介質(zhì)的溫度及外護(hù)管面要堅(jiān)持常溫。阻隔、反射層：目的是保證有機(jī)泡沫資料不會(huì)進(jìn)入無機(jī)硬質(zhì)耐高溫層。
Anti-corrosive coating: It is to prolong the service life of steel pipes and to maintain the outer steel pipes to prevent corrosion to the steel pipes. External protection steel pipe: In order to ensure the normal operation of the directly buried insulation pipe, maintain the insulation layer from the corrosion of open water, support the working pipe and be able to accept certain external loads. Steel sleeve steel directly buried insulation pipe polyurethane foam layer: the purpose is to ensure the temperature of the medium and the surface of the outer pipe should be kept at normal temperature. Barrier and reflective layer: the aim is to ensure that organic foam data will not enter the inorganic hard and high-temperature resistant layer.
