  • 幾種塑料管的特點和主要用途比較:
        PVC管 具有較好的抗拉、抗壓強度,但其柔性不如其他塑料管,耐腐蝕性優良,價格在各類塑料管中最便宜,但低溫下較脆 粘接、承插膠圈連接、法蘭螺紋連接 用于住宅生活、工礦業、農業的供排水、灌溉、供氣、排氣用管、電線導管、雨水管、工業防腐管等 
        CPVC管 耐熱性能突出,熱變形溫度為100℃,耐化學性能優良 粘接、法蘭螺紋連接 熱水管
        PE管 重量輕、韌性好,耐低溫性能較好,無毒,價格較便宜,抗沖擊強度高,但抗壓、抗拉強度較低 熱溶焊接、法蘭螺紋連接 飲水管、雨水管、氣體管道、工業耐腐蝕管道 
        PP管 耐腐蝕性好,具有較好的強度、較高的表面硬度、表面光潔度,具有一定的耐高溫性能 熱溶焊接、法蘭螺紋連接 化學污水、海水、油和灌溉的管道,用于室內混凝土地坪作采暖系統加熱管 
        ABS管 耐腐蝕性優良,重量較輕,耐熱性高于PE、PVC,但價格較昂貴。 粘接、法蘭螺紋連接 衛生潔具用下水管、輸乞管、污水管、地下電纜管、高防腐工業管道等 
        PB管 強度介地PE和PP之間,柔性介于LDPE和HDPE之間,其突出特點是抗蠕變性能(冷變形),反復繞纏而不斷,耐溫,化學性能也很好 熱熔焊接、法蘭螺紋連接 給水管、冷熱水管、燃氣管、地下埋高管道 
        GRP管 優良的耐腐蝕性、質輕、強度高、可設計性能好 承插膠圈連接、法蘭連接 廣泛用石油化工管道和大口徑給排水管
