塑料管材取代传统管材势不可挡

发布日期:2019-06-24 16:33 来源:http://jxhtlshl.com 点击:

世界各国在现代化进程中的历史经验表明,塑料管的发展速度均超过同期经济发展速度,用塑料管代替传统管材是历史发展不可抗拒的趋势。PE给水管材管件,即使在已建成密布塑料管网的发达国家,塑料管的应用量仍在逐年增长,例如1986年欧洲塑料管总用量为213.4万t,1998年增长到346.5万t,年均增长率为5.2%,超过同期国民经济增长速度。在过去10年中,中国塑料管市场年均增长率为20%,2000年、2002年及2003年产量分别达到70万-80万t、130万t及150万t,增长率为15%,其中PVC管占55%,PE管占40%。预计2010年前,国内塑料管材年均增长率仍将超过20%。

  在综合经济性方面,塑料管的优势正在被越来越多的用户所认识。塑料管的单价虽比水泥管略高,但工程总造价却不比水泥管高。天津市政工程设计院1992年起对UPVC双壁波纹管,1998年起对PE双壁波纹管棋牌评测网在埋地排水管中的应用进行了系统研究,结论为:"双壁波纹管的工程造价与混凝土平口管相当,比承插口混凝土管低30%。施工周期显著缩短,经济效益显著"。

  可将塑料埋地管分为实壁管和结构壁管2大类,压力管一般使用实壁管。环刚度代表排水管承受外压负载的能力,与管材的惯性矩和弹性模量成正比,与管径的立方成反比。在环刚度相同的条件下,使用结构壁管比使用实壁管节约材料50%-70%。结构壁管有6种类型:PVC双壁波纹管、PVC加筋管、HDPE双壁波纹管、HDPE缠绕管、克拉管和玻璃钢夹砂管。目前使用最多的是:Φ500mm以下,PVC双壁波纹管、PVC加筋管和HDPE双壁波纹管;Φ500mm以上,HDPE双壁波纹管、克拉管、缠绕管和玻璃钢夹砂管。大口径HDPE双壁波纹管是6种结构壁管中优点最突出的类型,主要原因是原料省、成本低、生产效率高、整体性能好、施工方便。
