2.暖氣管道，PPR熱水管和鋁塑管，哪一個(gè)比較合適？暖氣管道中的管材，如果是為PPR管材的話，那么，是為PPR熱水管。不過(guò)，也可以使用鋁塑管。如果將這兩個(gè)進(jìn)行比較的話，則無(wú)法判斷哪一種要好一些，因?yàn)樗鼈兏饔刑攸c(diǎn)，所以，是無(wú)法進(jìn)行判斷，因?yàn)闆]有可比性，只能說(shuō)在什么情況下，應(yīng)使用哪一種。，是否可以有接頭？PPR管材，如果其埋地敷設(shè)的話，那么在地面內(nèi)，是不能有接頭的，而在散熱器處接頭除外。此外，我們需要知道的是，PPR管材的安裝施工方案，應(yīng)根據(jù)施工圖紙、設(shè)計(jì)交底以及相關(guān)專業(yè)規(guī)范來(lái)進(jìn)行制定，以確保施工的準(zhǔn)確性和合理性，從而，可以避免一些不必要的問(wèn)題，以免影響到施工進(jìn)度和質(zhì)量。成都康泰PPR給水管規(guī)格型號(hào)對(duì)這個(gè)問(wèn)題，在PPR管材生產(chǎn)廠家無(wú)錫江通塑膠看來(lái)，其是一定及肯定的。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="四川川路PPR給水管批發(fā)價(jià)格,PPR給水管"

ppr給水管可以區(qū)分為熱水管和冷水管兩種，它們都是會(huì)在生活中用得到的水管道，但是熱水管和冷水管也是有所差別的。ppr熱水管是可以用作冷水管道，但是ppr冷水管道時(shí)不能用作熱水管道的。因?yàn)槔渌芘c熱水管的承受壓力不同，冷水管的壓力要小于熱水管，所以，如果把冷水管用在工作壓力較大的熱水管路上容易造成管壁破裂，但這不是一定的；并且ppr冷水管在高溫條件下使用的話，則易變形，且強(qiáng)度也會(huì)很大降低。有的管子把冷水用于熱水也能挺的住，但不管怎樣冷水管做熱水管路是不允許的，熱水管當(dāng)冷水管用是可以的；ppr冷水管一般都用做自來(lái)水管，ppr熱水管一般用做暖氣連接管，也可用于熱水器的熱水管路。由于ppr熱水管的承受壓力要比冷水管的大，所以熱水管的壁厚也要大于冷水管，因此ppr熱水管的價(jià)格要貴一些。熱水管上標(biāo)識(shí)有紅線，冷水管上標(biāo)識(shí)有藍(lán)線，并且有文字標(biāo)識(shí)，也有耐受壓力標(biāo)識(shí)，另外，如果同種規(guī)格的管子比較壁厚也能區(qū)分冷熱水管。 </p><p> 我們知道，家里裝修不管是廚房還是衛(wèi)生間都是用水比較多的地方，而用水多自然在施工的時(shí)候要提前布較多的ppr給水管來(lái)滿足用水需求。那么在選擇ppr給水管時(shí)，到底是用4分管好還是6分管好呢？其實(shí)很多家庭在裝修的時(shí)候都沒有好好考慮這個(gè)問(wèn)題，即使算家里選用了不同管徑的水管，也不知道其中的緣由。從ppr給水管本身上來(lái)說(shuō)，4分管和6分管的區(qū)別無(wú)非是管的直徑大小不同，常用的6分管的直徑為25mm，而4分管直徑則為20mm。通常情況下，市面上大多數(shù)水龍頭都是4分的接口，因此理論上來(lái)說(shuō)在布的時(shí)候只需要使用4分管可以了，而且相比于6分管還能節(jié)省一部分的材料錢，因?yàn)?分管單價(jià)是要比4分管要高的。 PPR管材，其的標(biāo)準(zhǔn)長(zhǎng)度，一般是為每根四米。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="四川川路PPR給水管批發(fā)價(jià)格,PPR給水管"

2.“聞”：有無(wú)氣味。PPR管主要材料是聚丙烯，好的管材沒有氣味，差的則有怪味，很可能是摻和了聚乙烯（即PE），而非聚丙烯。3.“捏”：PPR管具有相當(dāng)?shù)挠捕?，隨隨便便可以捏成變形的管，肯定不是PPR管。4.“砸”：好的PPR管，“回彈性”好，太容易砸碎的是碳酸鈣填料太多，自然不是好的PPR管。砸不碎的PPR管，也未必就是好管，關(guān)鍵是看原料和加工工藝。5.“燒”：點(diǎn)火一燒，很直觀也很管用。原料中混合了回收塑料和其他雜質(zhì)的PPR管會(huì)冒黑煙，有刺鼻氣味；好的材質(zhì)燃燒后不僅不會(huì)冒黑煙、無(wú)氣味，燃燒后，熔出的液體依然很潔凈。6.根據(jù)國(guó)家檢測(cè)標(biāo)準(zhǔn)，有些簡(jiǎn)單的檢測(cè)項(xiàng)目，可以通過(guò)感官來(lái)識(shí)別一些。不同顏色是加入了不同顏色的色母料。四川川路PPR給水管批發(fā)價(jià)格</p><p style="text-indent:25px">是有PPR和PB這兩個(gè)，由于PPR管材的價(jià)格要低于PB管材，所以，在暖氣管道上，是以PPR管材為主。四川川路PPR給水管批發(fā)價(jià)格</p><p> PPR水管的主要缺點(diǎn)是：耐高溫性，耐壓性稍差些，長(zhǎng)期工作溫度不能超過(guò)70℃；每段長(zhǎng)度有限，且不能彎曲施工，如果管道鋪設(shè)距離長(zhǎng)或者轉(zhuǎn)角處多，在施工中就要用到大量接頭；管材便宜但配件價(jià)格相對(duì)較高。不過(guò)，從綜合性能上來(lái)講，PPR管是性價(jià)比較高的管材，所以成為家裝水管改造的優(yōu)先材料。相對(duì)于其它幾種管：鍍鋅鐵管由于存在眾多缺點(diǎn)，建設(shè)部已于2000年明文禁用了；鋁塑管雖然耐高溫性能良好，施工方便但用作熱水管使用時(shí)，由于長(zhǎng)期的熱脹冷縮會(huì)造成管壁錯(cuò)位以致造成滲漏；銅管耐用、環(huán)保，但由于價(jià)格高、施工要求高而未被大面積采用。四川川路PPR給水管批發(fā)價(jià)格</p></p><br
