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，四川日豐PPR給水管批發(fā)價(jià)格。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)，四川日豐PPR給水管批發(fā)價(jià)格，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)，四川日豐PPR給水管批發(fā)價(jià)格，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。

管材中的PPR管材，其對(duì)大家而言，應(yīng)該是很熟悉了，因?yàn)?，它是無(wú)錫江通塑膠的重要產(chǎn)品，并且在前面，已經(jīng)開(kāi)始了其的學(xué)習(xí)工作，好讓大家熟悉和了解這一種管材。所以，接下來(lái)，還是這一話題，只不過(guò)在內(nèi)容上，是前面還沒(méi)有的，好讓大家有新的學(xué)習(xí)內(nèi)容。，如果其用作給水或排水管的話，那么，是否要進(jìn)行復(fù)驗(yàn)？PPR管材，如果其用作給水或排水管的話，那么，其是要進(jìn)行復(fù)驗(yàn)的，而且，這也是要認(rèn)真進(jìn)行的，不能有半點(diǎn)馬虎。而其具體執(zhí)行單位，是為管材所在地的建筑工程質(zhì)量檢測(cè)中心，來(lái)進(jìn)行該管材的復(fù)驗(yàn)工作。成都康泰塑膠PPR給水管規(guī)格型號(hào)所以一旦安裝打壓測(cè)試通過(guò)，絕不會(huì)再漏水，可靠度極高。</p><div

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> PPR水管為什么顏色不一樣？廠家供應(yīng)的PPR顆粒有不同顏色，比如灰色等，但是多數(shù)公司都是購(gòu)入透明原料，不同顏色是加入了不同顏色的色母料。>PPR水管顏色和質(zhì)量有必然的聯(lián)系么？沒(méi)有。但是白色PPR避光檢測(cè)不合格的情況要多些，而灰色、綠色則不存在這些問(wèn)題。另外受生活習(xí)慣影響，北方多用白色PPR管材，而南方則灰色PPR管較多。>PPR水管是分冷水管與熱水管如何區(qū)分？·PPR管是分冷水管與熱水管的，其區(qū)別是冷水管上有藍(lán)色標(biāo)識(shí)線，熱水管是紅色線。另外，PPR管道上面有諸如S5S4，一般S5S4為冷水管，壁厚較薄，，壁厚較厚。>PRR水管的連接技術(shù)有什么特點(diǎn)？·PPR管的接口采用熱熔技術(shù)，管口與管口之間完全融合到了一起，所以一旦安裝打壓測(cè)試通過(guò)，絕不會(huì)再漏水，可靠度極高。
