隨著建筑行業的迅速發展，聚丙烯管（PPR）也得到了更多的利用，下面我們來介紹一下PPR家裝管管材的應用及連接安裝方法：

（1）在(zai)現在(zai)建筑安裝(zhuang)工程(cheng)中，采暖和(he)給水(shui)用的大多是(shi)PPR管材（件）。其優點(dian)是(shi)安裝(zhuang)方便快(kuai)捷、經濟適用環保、重量(liang)輕(qing)、衛(wei)生無毒(du)、耐熱(re)性好、耐腐蝕、保溫性能(neng)好、壽(shou)命長等(deng)優點(dian)。管徑比公稱直(zhi)徑大一號(hao)。如(ru)PPR32 就(jiu)(jiu)相當(dang)(dang)于DN25，PPR63就(jiu)(jiu)相當(dang)(dang)于DN50.管徑具體分為(wei)(wei)(wei)DN20、DN25、DN32、DN40、DN50、DN63、DN75、DN90、DN110.管件種類繁(fan)多三通、彎(wan)頭、管箍、變(bian)徑、管堵、管卡(ka)、支(zhi)架、吊(diao)架。分冷(leng)熱(re)水(shui)管，冷(leng)水(shui)管為(wei)(wei)(wei)帶(dai)綠色(se)條(tiao)管，熱(re)水(shui)管為(wei)(wei)(wei)帶(dai)紅色(se)條(tiao)管。閥(fa)門有(you)PPR的球閥(fa)、截止閥(fa)、蝶閥(fa)、閘閥(fa)、有(you)外為(wei)(wei)(wei)PPR材料內為(wei)(wei)(wei)銅(tong)芯的。
