PPR聚氨酯保(bao)溫(wen)管(guan)可分熱(re)水管(guan)和冷水管(guan)

PPR聚(ju)氨酯(zhi)保(bao)溫(wen)(wen)(wen)管(guan)(guan)(guan)是一種由內管(guan)(guan)(guan)PPR管(guan)(guan)(guan)，外套管(guan)(guan)(guan)PVC管(guan)(guan)(guan)，中間聚(ju)氨酯(zhi)發泡保(bao)溫(wen)(wen)(wen)層一次發泡組合(he)成(cheng)型(xing)(xing)而成(cheng)，實現了(le)施(shi)工(gong)簡(jian)約、項目(mu)精(jing)致、保(bao)溫(wen)(wen)(wen)效果良好(hao)的工(gong)程(cheng)目(mu)標。廣泛應用于熱泵太陽能熱水(shui)(shui)(shui)系統(tong)(tong)(tong)、大型(xing)(xing)冷暖(nuan)中央空調(diao)水(shui)(shui)(shui)系統(tong)(tong)(tong)、北(bei)方自(zi)來水(shui)(shui)(shui)供水(shui)(shui)(shui)系統(tong)(tong)(tong)、工(gong)業余(yu)熱回收系統(tong)(tong)(tong)、家庭(ting)熱水(shui)(shui)(shui)管(guan)(guan)(guan)道(dao)(dao)、溫(wen)(wen)(wen)泉熱水(shui)(shui)(shui)系統(tong)(tong)(tong)、集(ji)中供熱管(guan)(guan)(guan)道(dao)(dao)、制冷管(guan)(guan)(guan)道(dao)(dao)、工(gong)業管(guan)(guan)(guan)道(dao)(dao)等中低(di)溫(wen)(wen)(wen)冷熱水(shui)(shui)(shui)保(bao)溫(wen)(wen)(wen)領域中。

　　由上可見，PPR聚氨酯保溫管(guan)可分(fen)熱(re)水管(guan)和冷水管(guan)，它們有什么區別呢(ni)？

　　1、PPR聚氨酯保溫管(guan)(guan)可用(yong)于熱水(shui)管(guan)(guan)，也可用(yong)于冷水(shui)管(guan)(guan)。但(dan)因為(wei)其特性，在(zai)(zai)低溫-5℃，點(dian)說在(zai)(zai)低于5℃溫度(du)就開始呈現易脆(cui)性，容易裂開，溫度(du)越低，程度(du)更高。所以更多地使用(yong)在(zai)(zai)熱水(shui)管(guan)(guan)。

　　2、PPR熱(re)水(shui)(shui)管(guan)的(de)壓(ya)(ya)力(li)通常(chang)為2.0Mpa，而PPR冷水(shui)(shui)管(guan)壓(ya)(ya)力(li)則是(shi)1.25Mpa或1.6Mpa。在溫度不低于(yu)0℃，熱(re)水(shui)(shui)管(guan)是(shi)可(ke)以當作冷水(shui)(shui)管(guan)使用(yong)，但不是(shi)很。

　　3、PPR熱水管(guan)管(guan)壁都比(bi)冷水管(guan)的(de)要厚(hou)，主要是承受更大的(de)內外壓力和有一(yi)定的(de)保(bao)溫作用。

　　4、PPR熱水(shui)保溫(wen)管(guan)(guan)工作(zuo)溫(wen)度為70℃左右(you)，管(guan)(guan)子(zi)承受溫(wen)度為95℃，而PPR冷水(shui)管(guan)(guan)一般(ban)為自(zi)來水(shui)管(guan)(guan)使用，管(guan)(guan)內(nei)水(shui)溫(wen)不(bu)可低(di)于0℃，否則容易結冰裂(lie)管(guan)(guan)。

　　5、PPR熱水(shui)保(bao)溫(wen)管(guan)的(de)(de)(de)主要(yao)作用就是(shi)(shi)熱水(shui)保(bao)溫(wen)，盡(jin)可能地將(jiang)熱水(shui)保(bao)溫(wen)時間更久，所(suo)以它的(de)(de)(de)內管(guan)是(shi)(shi)PPR管(guan)，中(zhong)間是(shi)(shi)聚氨(an)酯泡沫保(bao)溫(wen)層(ceng)，然后套入PVC排水(shui)管(guan)做(zuo)外層(ceng)防(fang)護(hu)。而PPR冷水(shui)管(guan)自(zi)然沒有(you)保(bao)溫(wen)的(de)(de)(de)定(ding)義(yi)，而有(you)些工(gong)程上也要(yao)用到PPR冷水(shui)保(bao)溫(wen)管(guan)，只有(you)防(fang)凍(dong)的(de)(de)(de)需求，管(guan)子在寒冷氣候不易爆裂，抗凍(dong)那么(me)就要(yao)做(zuo)好保(bao)溫(wen)工(gong)作。

　　6、PPR熱(re)水(shui)(shui)(shui)(shui)管(guan)(guan)比(bi)PPR冷水(shui)(shui)(shui)(shui)管(guan)(guan)的貴，原因在于熱(re)水(shui)(shui)(shui)(shui)管(guan)(guan)使用用途(tu)比(bi)較(jiao)廣，材質厚(hou)；而(er)冷水(shui)(shui)(shui)(shui)管(guan)(guan)相對(dui)于熱(re)水(shui)(shui)(shui)(shui)管(guan)(guan)，功(gong)能比(bi)較(jiao)少，比(bi)較(jiao)普通，管(guan)(guan)壁也薄。PPR熱(re)水(shui)(shui)(shui)(shui)管(guan)(guan)能走(zou)冷熱(re)水(shui)(shui)(shui)(shui)，而(er)PPR冷水(shui)(shui)(shui)(shui)管(guan)(guan)卻不能走(zou)熱(re)水(shui)(shui)(shui)(shui)。
