PVC-U給水管材

PVC-U給水管材

●給水用硬質聚氯乙烯管材

UPVC管材以衛生級PVC樹脂為主要原料,添加各種穩定劑、防老化劑、抗沖擊劑和其它助劑,經擠出加工成型而成不同壓力等級的各種規格型號的硬質聚氯乙烯管材。

主要用于給排水工程,亦可用于化工、建筑、農田排灌管道等。

●UPVC管材、管件的優點

(1)質輕UPVC的密度為1.35-1.46g/cm3,是同樣尺寸鋼管重量的1/8-1/5,因而運輸、安裝方便。

(2)耐腐蝕性好,使用壽命長。正常情況下使用壽命一般可達30-50年以上。

(3) 摩擦系數小,為0.0008左右,摩擦阻力小。

(4)不結垢,不生銹。 

(5)導熱性低。

(6)施工、安裝、維修方便。UPVC管道的安裝比鋼管、水泥管方便,它可通過粘接、焊接、熱熔接、螺紋連接、法蘭盤等方式連接,帶彈性密封圈接頭的PVC 管材可直接插入連接,勞動效率高,安裝速度快,維修方便。

(7)綜合價格便宜。UPVC的比重小,施工方便,使用壽命長,相對價格低廉。

(8)電絕緣性能好。UPVC塑料管是電的不良導體,可作為電線絕緣套管。使用安全可靠。其體積比電阻約為1-3 ×105cm,擊穿電壓達23-28千伏/mm。
