Description

热缩带保温地下埋置管
技术领域
    本实用新型涉及一种保温管的改进,具体的说是一种热缩带保温地下埋置管。 
背景技术
    目前采暖或生产用的输水管道、热水管道、煤气管道,一般都使用防腐保温管,以起到防腐、防冻、保温的作用,现在的防腐保温管,是在钢管的外壁上采用发泡工艺粘附上聚氨酯保温层,再在聚氨酯保温层的外面套装聚乙烯保护管,以保护聚氨酯保温层不受损坏,其不足之处在于:由于聚乙烯保护管是整体套装的,在套装的过程中,需要用大型设备进行套装,设备投资较大,提高了生产成本,同时,在管与管对口连接时,由于不能采用相同的聚乙烯保护管,致使材料的性能不统一,容易造成损坏,缩短了整个保温管的使用寿命。 
发明内容
本实用新型的目的在于提供一种结构简单、制作方便、设备投资小,有利于管口连接,延长使用寿命的热缩带保温地下埋置管。 
为了达到以上目的,本实用新型所采用的技术方案是:该热缩带保温地下埋置管,由钢管和聚氨酯保温层构成,聚氨酯保温层设在钢管的外壁上,其特征在于:在所述聚氨酯保温层的外壁上设有热缩带层。 
本实用新型的有益效果在于:结构简单、制作方便、设备投资小,有利于管口连接,延长了整体的使用寿命,降低了生产成本。 
附图说明
    附图1为本实用新型的结构断面剖视示意图。 
具体实施方式
参照附图制作本实用新型。该热缩带保温地下埋置管,由钢管1和聚氨酯保温层2构成,聚氨酯保温层2设在钢管1的外壁上,通过发泡工艺制成,其特征在于:在所述聚氨酯保温层2的外壁上设有热缩带层3,以便保护聚氨酯保温层2不受损坏,同时产生防水的作用。 
在制作本实用新型时,首先在钢管1的外壁上通过发泡工艺粘结固定上聚氨酯保温层2,然后在聚氨酯保温层2的外壁上缠绕热缩带,缠绕完成后,用喷灯加热即可形成热缩带层3。
