一种HDPE双臂波纹管
本技术涉及管道
,具体的说是一种HDPE双臂波纹管。
技术介绍
HDPE双壁波纹管材是以聚乙烯树脂为主要原料,加入适量助剂,经挤出成型,应用越来越广泛,逐渐运用到建筑、通信、农业中来。具有重量轻、阻力小、抗压强度高、施工方便等优点,是取代铸铁管和水泥砼管的理想材料。现有的HDPE双壁波纹管整体强度较差,受挤压容易产生破裂,并且凸起处长久使用之后容易受到外界的磨损,大大降低了使用寿命。HDPE双壁波纹管通常为平滑的内壁层和外轮廓呈波浪形的外壁层,由于结构原因,这类HDPE双壁波纹管的环刚度偏低,抗外压负载能力相对较差,管材容易发生变形。因此,为克服上述技术的不足而设计出一款结构简单,耐磨性好,抗外压负载能力强,环刚度高,管道不易破裂,能延长管道使用寿命的一种HDPE双臂波纹管,正是专利技术人所要解决的问题。
