Abstract

本实用新型涉及一种新型无规共聚聚丙烯不锈钢复合管,由不锈钢管为内层,外层为无规共聚聚丙烯管,在外层管与内层不锈钢管之间采用具有良好粘合性的热熔胶作粘接层,与已有技术相比具有机械强度高,刚性好,不变型、不生锈、不结垢、不渗漏、使用寿命长等特点。

Description

无规共聚聚丙烯不锈钢复合管
                           技术领域
本实用新型涉及塑料制管领域,是一种新型无规共聚聚丙烯不锈钢复合管。主要用于环境温度在-40C~+110C的液体输送。特别适用于热水输送系统,也可用于北方水暖气暖等高温供暖。
                           背景技术
已有低压流体输送管材,如生活给、排水管,采用金属管或塑料管,也有塑料与钢管复合管材。专利号为98222528和99242384的两件中国专利分别公开了内层为钢管、外层为塑料和内层为塑料、外层为钢管的两种塑钢复合管材。但仍然无法同时满足在输送过程中对环境温度变化、抗压、抗结垢、抗变形、耐腐蚀、耐高温、防渗漏、使用寿命长的要求。
                           发明内容
本实用新型的目的是提供一种无规共聚聚丙烯不锈钢复合管,克服已有技术的缺点,将各自的优点有机结合起来的一种新型塑料不锈钢复合管材。
本实用新型无规共聚聚丙烯不锈钢复合管的技术方案是:一种无规共聚聚丙烯不锈钢复合管,由塑料管、钢管组成,其特征在于内层为食品级不锈钢管,外层为无规共聚聚丙烯管,中间采用热熔胶粘接层。
本实用新型无规共聚聚丙烯不锈钢复合管,内层为不锈钢管,外层为无规共聚聚丙烯,中间层为热熔胶粘接层,使二者结合成体。外层发挥了聚丙烯管的优点,与管件同质热熔,保证连接处永不渗漏。内层为不锈钢管,发挥了机械强度高,刚性好、不会弯曲变形、光滑流畅、不生锈、不结垢、使用寿命长的特点,输送质量得到保证。
                          附图说明
图1是本实用新型无规共聚聚丙烯不锈钢复合管结构示意图。
                       具体实施方式
下面结合附图1对本实用新型的具体实施方式作进一步的说明。
本实用新型无规共聚聚丙烯不锈钢复合管由内层不锈钢管(1)、中间热熔胶粘接层(2)、和外层无规共聚聚丙烯或聚乙烯管(3)组成,生产时先将不锈钢带成型焊接成不锈钢管,再与热熔胶粘接层和无规聚聚丙烯一次挤出定型。

Claims (2)

1、一种无规共聚聚丙烯不锈钢复合管,其特征在于由食品级不锈钢管为内层(1),外层为无规共聚聚丙烯(3),中间粘接层采用热熔胶(2)。
2、根据权利要求书1所述的一种无规共聚聚丙烯不锈钢复合管,其特征在于不锈钢管为食品级不锈钢带焊接成型。
