摘　　要：玻璃钢管道具有经久耐用,耐腐蚀,重量轻,成本低,高效节能,寿命周期长和力学性能优良等特点,在油田与污水处理方面得到了广泛应用。然而在实际生产与测试过程中,环氧树脂粘度不同,管道的抗拉性能有所不同。为了提高环氧管道整体的抗拉强度,改善其力学性能,满足更高的工作要求,本文采用了芳香胺管道,通过对缠绕过程中树脂粘度的测量以及管道拉伸试验等,研究了环氧树脂粘度对玻璃钢管道抗拉强度的影响。结果表明:新配制的胶液粘度较小,为2800mPa·s,所生产的玻璃钢管道抗拉强度较大。随着生产进行,胶液循环,温度降低,胶液粘度增大,玻璃钢管道的抗拉强度降低。在以后的生产中,可通过对循环胶液加热或提高生产环境的温度等方法,提高玻璃钢管道的抗拉强度,对改善玻璃钢管道的力学性能,提升产品质量有重大意义。FRP pipes have been widely used in oilfield and sewage treatment due to their features of durability, corrosion resistance, light weight, low cost, high efficiency and energy saving, long life cycle and excellent mechanical properties. However, in the actual production and testing process, the tensile propertiesof the pipeline are different with the viscosity of epoxy resin. In order to improve the overall tensile strength of epoxy pipeline, improve its mechanical properties, to meet higher work requirements.In this paper, aromatic amine pipes are adopted, and the effect of epoxy resin viscosity on the tensile strength of FRP pipes is studied by measuring the viscosity of the resin during the winding process and the tensile test of the pipe.The results show that the viscosity of the newly prepared epoxy resin is relatively low(2800 mPa·s), and the tensile strength of the FRP pipe is relatively high.As the production goes on, the temperature decreases, the viscosity increases, and the tensile strength of FRP pipe decreases.In the future production, it is of great significance to improve the mechanical properties of FRP pipes and improve the quality of products by heating the circulating resin solution or increasing the temperature of the production environment.
