  3、性能与优点
  是带固定片的热收缩带(常称为搭盖式或开口式热收缩套),收缩率≥15%。主要用于管道补口防腐及防腐层大面积损伤、缺陷的补伤。
  
  对管体涂层的兼容性优良
  产品适用于各种管体防腐涂层如:二层聚乙烯(2PE)、三层聚乙烯(3PE)、三层聚炳烯(3PP)、粉末环氧(FBE)、保温夹克、煤焦油瓷漆、石油沥青。在管线的现场补口防腐中获得大量应用,效果良好。这已为许多管道工程所证实。
  
  抗蠕变性能好、使用寿命长
  配合性能优异的热熔胶及底漆,金环公司生产的热收缩带能适应不同的运行温度条件,抗蠕变性能好,寿命长能与管道同龄。
  
  预热温度低
  材料新工艺的应用为现场补口防腐提供了更为广阔的空间。我公司具有良好应用性能的无溶剂环氧底漆在补口时只需预热到40℃-60℃便可涂刷,可即时安装收缩,可获得高的剥离强度,为工程提供了极大的方便。
  
  在底漆“湿状态”下安装
  在底漆“湿状态”下进行热收缩套的安装,不仅能保证安装后的质量稳定可靠而且操作便捷,对提高施工作业效率十分有利。
  
  新材料、新工艺、新技术,使产品性能、质量持续保持优良
  公司十分重视高科技应用,坚持持续改进、应用新材料、新工艺、新技术,使产品性能、质量持续保持优良。金环的“无胶粘结技术”新型固定片,使在现场安装好固定片后,用火焰沿周向(火焰履盖固定片)加热收缩时,能保证热收缩带头尾搭接处几乎无滑移,使整个补口热熔胶能充分融化(使搭接部位下层即贴钢管的胶层都烤软发粘起到防腐的作用)。安装质量得到很大的提高。同时,补口处胶粘剂的粘结性能进一步提高,它不仅在高温和低温的较宽范围内粘结性能显著增强,同时具有高的抗剪切强度。从而保证管道补口防腐质量更为可靠。
  
  有优异的防水密封性
  由性能优异的热熔胶、辐射交联聚乙烯基材、无溶剂环氧底漆等材料组成,防腐性能好、收缩速度快、密封性、防水性能好、耐酸硷、抗化学腐蚀。

  Features and Benefits

  HG-4 is a wraparound sleeve with a closure patch. The shrinkable ratio is≥15%. It is mainly applied to pipe joint corrosion protection and the prosthesisses of wide range damage.

  

  Excellent coating compatibility

  HG-4 can be applied to a wide range of pipe coating including 2 layers polyethylene, 3 layers polyethylene, 3 layers polypropylene, fusion bonded epoxy, insulated jacket, coal tar primer. It can be used for corrosion protection of pipe joint and corrosion seal of reducer or valve. The effectiveness and excellence have been approved by many pipeline projects.

  

  Apply with the primer at "wet state"

  The heat shrinkable sleeve is applied on the "wet state" of primer allowing formation of strong mechanical and chemical bonds, allows fast application, combined with high performance.

  

  Rapid installation

  The adoption of new materials and updated technology further predigests the installation. The liquid epoxy primer provided by Jinhuan can be used at a low preheating temperature which between 40 ºC~60ºC, quick, reliable field installation is easy to accomplish. The most recent innovation is the “adhesive agglutinated closure patch”. It has further improved the installation quality of HG-4 at job site. It has facilitated of heat melt adhesive, improved the lap shear strength.

  

  Long term corrosion protection

  HG-4 provides excellent resistance to soil creeping stresses and chemical attach. With the closure patch, product’s structure can guarantee more effective waterproof when it used on the buried and off-sea pipeline. The high performance cross linked backing in combination with adhesive, can resists adverse environments.
