隨著時代的發展，ppr家裝管在我國得到廣泛應用。其要如何選擇？和pe市政工程管-湖北響叮當塑料股份有限公司的小編簡單了解。

選購管(guan)(guan)材(cai)(cai)(cai)的(de)時候要(yao)注(zhu)意管(guan)(guan)材(cai)(cai)(cai)內徑(jing)是(shi)(shi)(shi)否勻稱，管(guan)(guan)徑(jing)粗細不(bu)勻稱會影響兩個接口的(de)對(dui)接。PPR管(guan)(guan)材(cai)(cai)(cai)的(de)標(biao)(biao)準長度為每根(gen)四米(mi)，買的(de)時候要(yao)問(wen)清楚(chu)商(shang)家(jia)說的(de)是(shi)(shi)(shi)每根(gen)管(guan)(guan)材(cai)(cai)(cai)的(de)價(jia)格(ge)(ge)還是(shi)(shi)(shi)每米(mi)管(guan)(guan)材(cai)(cai)(cai)的(de)價(jia)格(ge)(ge)，管(guan)(guan)材(cai)(cai)(cai)送到以后要(yao)記得抽查管(guan)(guan)材(cai)(cai)(cai)的(de)長度是(shi)(shi)(shi)否符合要(yao)求；家(jia)裝中用(yong)(yong)(yong)到的(de)主要(yao)是(shi)(shi)(shi)20mm，25mm兩種(zhong)（分(fen)別(bie)俗稱4分(fen)管(guan)(guan)、6分(fen)管(guan)(guan)）,其(qi)中4分(fen)管(guan)(guan)用(yong)(yong)(yong)到的(de)更多些(xie)。一(yi)般總管(guan)(guan)用(yong)(yong)(yong)6分(fen)管(guan)(guan)，分(fen)管(guan)(guan)用(yong)(yong)(yong)4分(fen)管(guan)(guan)；PPR水(shui)管(guan)(guan)是(shi)(shi)(shi)分(fen)冷熱水(shui)管(guan)(guan)的(de)，管(guan)(guan)壁厚薄不(bu)一(yi)樣，冷水(shui)管(guan)(guan)不(bu)能(neng)用(yong)(yong)(yong)做熱水(shui)管(guan)(guan)，分(fen)辨(bian)冷熱水(shui)管(guan)(guan)的(de)簡(jian)便方法是(shi)(shi)(shi)熱水(shui)管(guan)(guan)上有(you)一(yi)條紅線標(biao)(biao)記；家(jia)用(yong)(yong)(yong)給水(shui)管(guan)(guan)普(pu)遍(bian)選用(yong)(yong)(yong)PP-R水(shui)管(guan)(guan)、鋼(gang)塑(su)水(shui)管(guan)(guan)、銅管(guan)(guan)，鋼(gang)塑(su)管(guan)(guan)材(cai)(cai)(cai)價(jia)格(ge)(ge)相對(dui)高些(xie)，而(er)PP-R水(shui)管(guan)(guan)的(de)配(pei)件價(jia)格(ge)(ge)較鋼(gang)塑(su)管(guan)(guan)配(pei)件高，銅管(guan)(guan)價(jia)格(ge)(ge)較貴，價(jia)格(ge)(ge)相當于PP-R管(guan)(guan)的(de)4倍左右(you)。

從綜合性(xing)能(neng)上來講，PP-R管(guan)是(shi)目前性(xing)價比較高的(de)管(guan)材，所以成為家裝水(shui)管(guan)改造的(de)材料。
