一、聚(ju)氨(an)酯保温(wen)(wen)钢管(guan)(guan)制(zhi)造(zao)产品(pin)结构保温(wen)(wen)管(guan)(guan)由(you)钢管(guan)(guan)，腐剂，聚(ju)氨(an)脂硬质泡沫保温(wen)(wen)层和(he)高(gao)密度聚(ju)外套(tao)管(guan)(guan)结合的预制(zhi)管(guan)(guan)，再者也是有的这种直(zhi)埋(mai)保温(wen)(wen)管(guan)(guan)在(zai)利用的时候，就会因为这种材(cai)料上面的聚(ju)氨(an)酯之类(lei)的东(dong)西(xi)，在(zai)经过酸(suan)碱(jian)之类(lei)的里面是能够很好的保证自己(ji)化学(xue)性(xing)质的性(xing)。

二、聚氨(an)(an)酯保(bao)温(wen)(wen)(wen)管(guan)(guan)(guan)(guan)又(you)称聚氨(an)(an)酯直(zhi)(zhi)埋(mai)保(bao)温(wen)(wen)(wen)管(guan)(guan)(guan)(guan)，直(zhi)(zhi)埋(mai)保(bao)温(wen)(wen)(wen)管(guan)(guan)(guan)(guan)等，广(guang)泛应用与地下直(zhi)(zhi)埋(mai)保(bao)温(wen)(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)道工程的(de)保(bao)温(wen)(wen)(wen)隔热(re)，具有施工速度(du)快、造(zao)价低(di)、寿命长等诸多优点(dian)。直(zhi)(zhi)埋(mai)保(bao)温(wen)(wen)(wen)管(guan)(guan)(guan)(guan)相(xiang)对与其他(ta)保(bao)温(wen)(wen)(wen)材料优势(shi)为明显。聚氨(an)(an)酯直(zhi)(zhi)埋(mai)保(bao)温(wen)(wen)(wen)管(guan)(guan)(guan)(guan)可以在(zai)工厂(chang)制作也可以现场直(zhi)(zhi)接制造(zao)，边(bian)制造(zao)边(bian)安装(zhuang)，大大加快了(le)施工速度(du)，节约了(le)宝贵的(de)时间和面积，为赶工期抢了(le)的(de)保(bao)障。聚氨(an)(an)酯保(bao)温(wen)(wen)(wen)管(guan)(guan)(guan)(guan)一次安装(zhuang)永(yong)远受益，只要里(li)面的(de)介(jie)质无缝管(guan)(guan)(guan)(guan)（螺(luo)旋管(guan)(guan)(guan)(guan)等）不坏不腐蚀，外(wai)面的(de)保(bao)温(wen)(wen)(wen)层就(jiu)能完好无损，高性能的(de)聚氨(an)(an)酯与管(guan)(guan)(guan)(guan)道同寿。

三、聚(ju)(ju)氨(an)酯(zhi)(zhi)直埋(mai)保(bao)(bao)(bao)温(wen)(wen)(wen)(wen)管(guan)(guan)只要埋(mai)于(yu)土中(zhong)(zhong)即可(ke)，无需(xu)做(zuo)暖气沟(gou)，施(shi)工时用(yong)挖(wa)掘机按(an)线(xian)路挖(wa)槽(cao)，放入(ru)聚(ju)(ju)氨(an)酯(zhi)(zhi)保(bao)(bao)(bao)温(wen)(wen)(wen)(wen)管(guan)(guan)焊接牢(lao)固(gu)，做(zuo)好保(bao)(bao)(bao)温(wen)(wen)(wen)(wen)接头即可(ke)，由于(yu)聚(ju)(ju)氨(an)酯(zhi)(zhi)保(bao)(bao)(bao)温(wen)(wen)(wen)(wen)管(guan)(guan)自己抗压强度(du)大(da)，外护(hu)高密度(du)聚(ju)(ju)外壳(qiao)，所(suo)以耐(nai)腐(fu)蚀、，抵抗恶劣优势(shi)明显(xian)。聚(ju)(ju)氨(an)酯(zhi)(zhi)直埋(mai)保(bao)(bao)(bao)温(wen)(wen)(wen)(wen)管(guan)(guan)保(bao)(bao)(bao)温(wen)(wen)(wen)(wen)效果好，它的(de)导热系数仅为0.03，优于(yu)其他同类保(bao)(bao)(bao)温(wen)(wen)(wen)(wen)产品。大(da)大(da)加快了热量的(de)散发速(su)度(du)，聚(ju)(ju)氨(an)酯(zhi)(zhi)保(bao)(bao)(bao)温(wen)(wen)(wen)(wen)管(guan)(guan)可(ke)以适(shi)合(he)多种温(wen)(wen)(wen)(wen)度(du)介(jie)质工作(zuo)，几乎高温(wen)(wen)(wen)(wen)下可(ke)以让管(guan)(guan)道中(zhong)(zhong)加入(ru)岩棉等复合(he)保(bao)(bao)(bao)温(wen)(wen)(wen)(wen)层，从而使聚(ju)(ju)氨(an)酯(zhi)(zhi)保(bao)(bao)(bao)温(wen)(wen)(wen)(wen)管(guan)(guan)的(de)抗高温(wen)(wen)(wen)(wen)性能大(da)大(da)加强。

四(si)、聚氨(an)(an)酯(zhi)直(zhi)(zhi)埋(mai)保(bao)温(wen)管(guan)的结构和特点。聚氨(an)(an)酯(zhi)直(zhi)(zhi)埋(mai)保(bao)温(wen)管(guan)是由输送(song)介质(zhi)的内(nei)钢管(guan)，外套(tao)管(guan)和在(zai)内(nei)钢管(guan)和外套(tao)管(guan)之间填充的憎水(shui)不燃型聚氨(an)(an)酯(zhi)保(bao)温(wen)层紧密结合而制(zhi)成的整(zheng)体(ti)(ti)预制(zhi)管(guan)材(cai)，保(bao)温(wen)层采用发(fa)泡工(gong)(gong)艺使其和外套(tao)管(guan)紧密在(zai)一(yi)起(qi)。因(yin)为聚氨(an)(an)酯(zhi)直(zhi)(zhi)埋(mai)保(bao)温(wen)管(guan)的管(guan)道是直(zhi)(zhi)埋(mai)的，保(bao)温(wen)管(guan)道直(zhi)(zhi)接承(cheng)受土壤及(ji)地(di)面(mian)活(huo)荷(he)载，同时又受到地(di)下(xia)潮气及(ji)地(di)下(xia)水(shui)侵(qin)蚀，因(yin)此，聚氨(an)(an)酯(zhi)直(zhi)(zhi)埋(mai)保(bao)温(wen)管(guan)在(zai)防水(shui)、防腐及(ji)机械强(qiang)度等方(fang)面(mian)性能都(dou)要(yao)求较高。因(yin)此，仅管(guan)道一(yi)项直(zhi)(zhi)埋(mai)管(guan)工(gong)(gong)程(cheng)造价较高。但因(yin)聚氨(an)(an)酯(zhi)直(zhi)(zhi)埋(mai)保(bao)温(wen)管(guan)工(gong)(gong)程(cheng)综(zong)合造价较低，施工(gong)(gong)简(jian)便，和地(di)沟(gou)敷设相比，节约土石方(fang)工(gong)(gong)程(cheng)量(liang)、砖砌混凝(ning)土工(gong)(gong)程(cheng)量(liang)，施工(gong)(gong)工(gong)(gong)期缩短(duan)一(yi)半(ban)以上。
