Description

硝酸亚铁用预应力钢筒混凝土输送管
技术领域
本发明涉及硝酸亚铁反应系统领域，尤其涉及硝酸亚铁用输送管。
背景技术
目前用于输送压力流体的钢管屈服强度较低，因此，当需要制造耐压强度高的钢
管时，就需要将钢管的管壁设计的非常厚，以满足输送压力流体的目的。
但是，钢管加厚带来的弊端也是很明显的，例如，钢管壁加厚，导致生产每根钢管的用钢量增大，原材料成本提高 ；又比如，钢管壁加厚，导致钢管重量加大，运输及施工难度都会增大。另外，钢材属于高耗能、高排放产品，使用量的增大，必然导致能源的大量消耗，尤其是不可再生资源的消耗，这也非常不符合当前的节能环保趋势。
市场上通过在钢管内壁设置混凝土层来解决上述问题，但混凝土表面粗糙长期冲刷会导致脱落，并且输送效率较低，在用于硝酸亚铁管路输送中，由于腐蚀性较大，混凝土层容易被腐蚀，影响了使用寿命，有待改进。
发明内容
本发明针对现有技术的不足，提供了一种内壁光滑，防腐耐磨，输送效率提高15%~20%的硝酸亚铁用预应力钢筒混凝土输送管。
为实现本发明目的，提供了以下技术方案：硝酸亚铁用预应力钢筒混凝土输送管，包括基管，基管外壁设置有混凝土层，混凝土层内设置有环向缠绕的预应力钢丝，混凝土层外还包覆有水泥浆沙层，其特征在于基管内壁上设有纯锌涂层，纯锌涂层上涂覆有涂塑层，所述涂塑层为环氧树脂，所述涂塑层厚度为10~20mm。
作为优选，环向缠绕的预应力钢丝上喷涂有环氧树脂。
作为优选，所述水泥浆沙层外部设有环氧煤沥青防腐层。
本发明的有益效果：本发明通过对管内壁增设纯锌涂层和涂塑层，大大提供了输送性能，并且有效防腐。
附图说明
图1为本发明的结构示意图。
具体实施方式
硝酸亚铁用预应力钢筒混凝土输送管，包括基管1，基管1外壁设置有混凝土层2，混凝土层2内设置有环向缠绕的预应力钢丝3，混凝土层2外还包覆有水泥浆沙层4，基管1内壁上设有纯锌涂层5，纯锌涂层5上涂覆有涂塑层6，所述涂塑层6为环氧树脂，所述涂塑层6厚度为10~20mm。环向缠绕的预应力钢丝3上喷涂有环氧树脂。所述水泥浆沙层4外部设有环氧煤沥青防腐层7。
