Abstract
一种煤矿井下用聚乙烯涂层复合钢管，在钢管的内外周面复合有抗静电阻燃聚乙烯涂层。它具有承压高、耐腐蚀、质量轻、抗静电、阻燃、免维护、安装方便的特点，特别适合煤矿井下使用。
Description
技术领域：
本实用新型涉及一种用于煤矿井下用复合钢管，尤其是一种带有聚乙烯涂层的复合钢管。
背景技术：
传统的钢管用于煤矿井下时，易腐蚀，需要经常维护；而塑料管强度低，承压低，不适合在煤矿井下使用。
发明内容：
本实用新型的目的是提供一种煤矿井下用聚乙烯涂层复合钢管，满足矿用管材既要求承压高，又耐腐蚀的要求。
本实用新型的目的是以如下方式实现的：该煤矿井下用聚乙烯涂层复合钢管，是在经前处理后的钢管内外周面复合有抗静电阻燃聚乙烯涂层，形成了三层结构，钢管起到承压作用，内层与外层的抗静电阻燃聚乙烯涂层，既耐腐蚀，又满足煤矿井下对抗静电和阻燃的要求。
该复合钢管具有承压高、耐腐蚀、质量轻、抗静电、阻燃、免维护、安装方便的特点，特别适合煤矿井下使用。
附图说明：
附图是本实用新型煤矿井下用聚乙烯涂层复合钢管的结构示意图。
具体实施方式：
参照附图，经前处理后的钢管2，经特殊工艺内外复合上一层抗静电阻燃的聚乙烯涂层3、1。
