    钢丝网骨架塑料复合管的性能比较   钢丝网骨架塑料复合管是一过改良的新型的钢骨架塑料复合管。这种管材又称为srtp管。这种新型管道是用高强度过塑钢丝网骨架和热塑性塑料聚乙烯为原材料,钢丝缠绕网作为聚乙烯塑料管的骨架增强体,以高密度聚乙烯(HDPE)为基体,采用高性能的HDPE改性粘结树脂将钢丝骨架与内、外层高密度聚乙烯紧密地连接在一起,使之具有优良的复合效果。因为有了高强度钢丝增强体被包覆在连续热塑性塑料之中,因此这种复合管克服了钢管和塑料管各自的缺点,而又保持了钢管和塑料管各自的优点。
      钢丝网骨架塑料复合管,采用了优质的材质和先进的生产工艺,使之具有更高的耐压性能。同时,该复合管具有优良的柔性,适用于长距离埋地用供水、输气管道系统。钢丝网骨架聚乙烯复合管采用的管件是聚乙烯电熔管件。连接时,利用管件内部发热体将管材外层塑料与管件内层塑料熔融,把管材与管件可靠地连接在一起。
      钢丝网骨架聚乙烯复合管道是一种性能优异的新型管道,广泛应用于油田、电厂、化工石化企业、自来水公司、市政燃气、海水利用管路等各领域。
      产品特点:
      1.具有超过塑料管强度的较高强度、刚性、抗冲击性、双面防腐,具有与塑料管相同的防腐性能,而且耐腐蚀。
      2.使用温度提高。导热系数低,冬季使用外壁不需要保温,夏季使用亦不结露。内壁光滑,不结垢,水头损失比钢管低30%。
      3.管道连接采用电热熔连接,技术成熟。
      4.管件规格品种多,重量轻,运输及施工方便。
      5.管材总体可靠性高,在正常条件下,使用寿命可达50年。
      6.成本低廉,卫生无毒,是球墨铸铁管、钢管、镀锌管的最佳替代品。
    7.电热熔接头抗轴向拉力能力强,通过空隙,电热熔管件与管材内壁和外壁实际上连为一体,与增强骨架也为一体。

    钢丝网骨架塑料合管与焊接钢骨架塑料复合管的性能比较:
      第一:钢丝网骨架塑料合管与焊接钢骨架塑料复合管生产工艺不一样
      1.复合结构。焊接钢骨架塑料复合管,以普通碳钢钢丝为基材,钢丝虽然较粗,但抗拉强度只有400Mpa,工艺复杂,产品质量波动性较大。钢丝网骨架塑料(复合管,以高强应钢丝(1950Mpa以上)为基材,采取二次复合的方式,钢丝呈54.7度斜向缠绕在管材上,使得管材在受到内压时可向轴向和环向均匀分散受力,在确定钢丝直径和密度时采用了较高的安全系数。
      2.端面窜水。焊接钢骨架塑料复合管,由于PE材质的管材与钢板之间必然存在的间隙,截断管材时,其端面虽有封口,但使用电熔管件加热时封口易脱落。安装后会发生介质窜入钢板与塑料之间的缝隙,导致整个管路系统的承压能力下降。致使管材在低压力便被破坏,造成管道失效。
      第二:钢丝网骨架塑料合管与焊接钢骨架塑料复合管产品标准不一样。钢丝网骨架塑料复合管执行CJ/T189-2007 ,钢骨架复合管执行标准为CJ/T123-2004;
      第三:钢骨架复合管可以架空,钢丝网复合管不能架空。
