    華亞PVC管材的性能及適用范圍是什么?下面為大家進行具體說明:
    1.重量輕,僅為金屬管材的1/6~1/7左右,便于運輸。
    2.采用非螺旋連接,安裝方便,安裝費用低。
    3.隔音、隔熱保溫性能好,塑料的導熱系數僅為金屬的1/100。
    4.耐化學腐蝕性好,永不生銹。
    5.管壁光滑,水流阻力小,流量可增大30%,不結垢,不滋生細菌,無水垂音。
    6.使用壽命長久,一般可達20~50年。
    7.外表美觀。
    但UPVC管材耐壓強度不高,不適于高層建筑,只適用100米以下的低層建筑;耐熱溫度低,只適用于冷水的輸送;另外,對于含鉛量低的UPVC低毒管材,在安裝使用初期,為“洗滌”從管材中擴散而來可能超過飲用水標準的鉛及VCM等有害物質,必須進行管道沖洗及打壓試水,使有毒物質的含量下降到衛生合格水平。
