Glass fiber reinforced plastic storage tank leak repairing method

Abstract

The invention discloses a glass fiber reinforced plastic storage tank leak repairing method. The method comprises the following steps that S1, a glass fiber reinforced plastic storage tank is cleaned and aired; S2, external leakage points on the outer side surface of the glass fiber reinforced plastic storage tank are determined, and the peripheral positions of the external leakage points are polished and subjected to air bath cleaning; S3, assembly flanges are installed at the positions corresponding to the external leakage points, and the assembly flanges integrally cover the external leakage points; S4, the assembly flanges are connected, liquid is introduced into the glass fiber reinforced plastic storage tank, and pressurizing and pressure maintaining are conducted; S5, whether the inner side surface of the glass fiber reinforced plastic storage tank has a sweating phenomenon or not is observed, and marking is conducted one by one; and S6, the marked areas are repaired one by one until all the areas are repaired. According to the glass fiber reinforced plastic storage tank leak repairing method, aiming at the layered structure characteristics of a glass fiber reinforced plastic material, the leakage point in the glass fiber reinforced plastic storage tank is accurately found through the operation of reverse pressurization from outside to inside, convenience is provided for subsequent repair operation, and the repair difficulty of operators is reduced.

Description

technical field [0001] The invention relates to an equipment maintenance method, in particular to a leak detection and repair method for a glass fiber reinforced plastic storage tank, and belongs to the field of glass fiber reinforced plastic series equipment maintenance. Background technique [0002] Fiber Reinforced Plastics (FRP), scientific name fiber reinforced plastics, generally refers to reinforced plastics with glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix, glass fiber or its products as reinforcement materials, due to its It has the advantages of stable performance, high mechanical strength and corrosion resistance. FRP materials are often used in the production of storage tanks, pipelines, towers and other series of equipment. [0003] Taking the glass fiber reinforced plastic storage tank equipment widely used in the market as an example, the common glass fiber reinforced plastic storage tank equipment has obvious layered str...
