Description

一种涂塑复合钢管
技术领域
本发明涉及一种钢管，具体涉及一种涂塑复合钢管。
背景技术
目前，随着国家经济的快速发展，城乡基础设施的建设也在逐步完善，与人们生活相关的消防、给水、建筑、燃气以及煤矿等行业都离不开输送管材，由于现有管材在密封性、防腐性能、流体阻力、机械强度、使用寿命、适用范围等方面不能满足需求。因此，管道行业也亟待更快发展。
发明内容
本发明在于提供一种涂塑复合钢管，以克服上述缺陷，这种钢管附着力强，壁面光滑，流体阻力小，而且具有良好的抗静电、阻燃和耐候等特性。
为达到上述目的，本发明在于提供以下技术方案：
一种涂塑复合钢管，包括钢管本体，所述钢管本体的外壁设有外环氧树脂层，所述钢管本体的内壁设有内环氧树脂层。
上钢管本体的通径为50-1200mm。
上述外环氧树脂层的厚度为0.30-0.5mm。。
上述内环氧树脂层的厚度为0.30-0.45mm。
附图说明
图1为本发明整体结构示意图
图中1——钢管本体      2——外壁     3——外环氧树脂层
4——内壁     5——内环氧树脂层
具体实施方式
下面结合附图及实施例，对本发明做进一步详细的阐述。
一种涂塑复合钢管，包括钢管本体1，所述钢管本体1的外壁2设有外环氧树脂层3，所述钢管本体1的内壁4设有内环氧树脂层5。
上述钢管本体1的通径为50-1200mm。
上述外环氧树脂层3的厚度为0.30-0.5mm。。
上述内环氧树脂层5的厚度为0.30-0.45mm。
由于采用了上述结构，与塑料管材相比，本发明具有机械强度高、耐腐蚀、摩擦系数小、使用寿命长等优点，与镀锌钢管相比，本发明具有防腐性、阻燃、抗静电等方面的优势，而且本发明的应用范围更为广泛，同时，还具有良好的耐候性。
