Description
技术领域 technical field
本实用新型涉及一种复合管，特别是涉及一种聚氨酯螺旋复合耐磨管。 The utility model relates to a composite pipe, in particular to a polyurethane spiral composite wear-resistant pipe.
背景技术 Background technique
在现有技术中，传统的聚氨酯复合管从外到内分别由油漆防腐层、钢管、聚氨酯三层组成，在使用过程中主要存在以下缺点：（1）聚氨酯喷涂在钢管内壁，因钢管内壁较为光滑，长时间使用容易导致聚氨酯层脱落；（2）因钢管与聚氨酯层的膨胀系数不同，在受热条件下容易引起钢管和聚氨酯层的分离。 In the existing technology, the traditional polyurethane composite pipe is composed of three layers of paint anti-corrosion layer, steel pipe and polyurethane from the outside to the inside. During use, there are mainly the following disadvantages: (1) Polyurethane is sprayed on the inner wall of the steel pipe, because the inner wall of the steel pipe is relatively Smooth, long-term use will easily cause the polyurethane layer to fall off; (2) Due to the different expansion coefficients of the steel pipe and the polyurethane layer, it is easy to cause the separation of the steel pipe and the polyurethane layer under heated conditions.
发明内容 Contents of the invention
本实用新型所要解决的技术问题在于针对现有技术的不足，提供了一种聚氨酯螺旋复合耐磨管。 The technical problem to be solved by the utility model is to provide a polyurethane spiral composite wear-resistant pipe for the deficiencies of the prior art.
本实用新型采用的技术方案是： The technical scheme that the utility model adopts is:
聚氨酯螺旋复合耐磨管，从外到内由聚氨酯防腐层、轻质螺旋加强钢管、聚氨酯耐磨层组成；轻质螺旋加强钢管表面附着有聚氨酯防腐层，轻质螺旋加强钢管内衬聚氨酯耐磨层，轻质螺旋加强钢管与聚氨酯耐磨层粘连在一起，轻质螺旋加强钢管内壁呈麻纹状，增加了粗糙度，增强了聚氨酯耐磨层与轻质螺旋加强钢管附着力。 Polyurethane spiral composite wear-resistant pipe is composed of polyurethane anti-corrosion layer, light-weight spiral reinforced steel pipe and polyurethane wear-resistant layer from outside to inside; the surface of light-weight spiral-reinforced steel pipe is attached with polyurethane anti-corrosion layer, and the light-weight spiral-reinforced steel pipe is lined with polyurethane wear-resistant layer, the lightweight spiral reinforced steel pipe and the polyurethane wear-resistant layer are adhered together, the inner wall of the lightweight spiral reinforced steel pipe is textured, which increases the roughness and enhances the adhesion between the polyurethane wear-resistant layer and the lightweight spiral reinforced steel pipe.
所述轻质螺旋加强钢管外壁附着有波峰螺旋加强筋，增强了轻质螺旋加强钢管的强度、减低了生产成本、重量比普通钢管可减轻30%。 The outer wall of the light-weight spiral reinforced steel pipe is attached with wave-crested spiral reinforcement ribs, which enhances the strength of the light-weight spirally reinforced steel pipe, reduces production costs, and can reduce the weight by 30% compared with ordinary steel pipes.
本实用新型具有优异的耐磨性，由于内衬聚氨酯有较好的弹性，大大减轻了介质对管道内壁的直接强烈冲刷造成的磨损，其耐磨寿命是钢管的十几倍；内衬聚氨酯弹性体具有对称的分子结构，是对外呈无极性状态，形成不了对浆液中的Ca2+、Co32-、HCO3、OH等离子的吸附作用，形不成垢层，因此具有较好的耐酸、耐碱、防结垢性能；轻质螺旋加强钢管内壁呈麻纹状，增加了粗糙度，增强了聚氨酯耐磨层与轻质螺旋加强钢管附着力，避免了轻质螺旋加强钢管与聚氨酯耐磨层的分离问题。 The utility model has excellent wear resistance, because the lining polyurethane has good elasticity, which greatly reduces the wear caused by the direct and strong washing of the inner wall of the pipeline by the medium, and its wear-resistant life is more than ten times that of the steel pipe; the lining polyurethane is elastic The body has a symmetrical molecular structure and is in a non-polar state to the outside. It cannot form an adsorption effect on Ca2+, Co32-, HCO3, OH and other ions in the slurry, and cannot form a scale layer. Therefore, it has good acid resistance, alkali resistance and anti-coagulation. Scale performance; the inner wall of the light-weight spiral reinforced steel pipe is grainy, which increases the roughness, enhances the adhesion between the polyurethane wear-resistant layer and the light-weight spiral-reinforced steel pipe, and avoids the separation of the light-weight spiral-reinforced steel pipe and the polyurethane wear-resistant layer.
