Fusion method of glass reinforced plastic pipe and steel flange

Abstract

The invention discloses a glass fiber reinforced plastic pipe and steel flange fusion method which is based on five parts, namely a glass fiber reinforced plastic pipe, a waterproof rubber ring, a steel flange, a steel hook and a hand lay-up stainless steel material, and comprises the following steps: S1, taking the caliber glass fiber reinforced plastic pipe needing to be connected, and polishing the port of the glass fiber reinforced plastic pipe; a circle of pipe groove is formed in the inner side wall of the pipe end of the glass fiber reinforced plastic pipe. The glass fiber reinforced plastic pipe and the steel flange are directly connected into a whole, the installation efficiency is improved, the connecting strength is improved through the design of the reinforcing ribs and the barbs, the waterproof capacity of the pipe is improved through the arrangement of the rubber rings, it is guaranteed that water leakage is avoided when the glass fiber reinforced plastic pipe and the flange are connected, and when the glass fiber reinforced plastic pipe is used, water leakage is avoided. And the matching use of other metal accessories is not influenced.

Description

technical field [0001] The invention relates to the technical field of drainage building materials, in particular to a fusion method of glass steel pipes and steel flanges. Background technique [0002] There are more and more experiments on FRP in municipal drainage projects and various drainage projects, which have greatly improved the quality and drainage efficiency of drainage pipes. However, when FRP drainage pipes are connected with steel pipes or steel ball valves, there is always a certain The main problems are: [0003] 1. Due to the different materials of glass steel pipes and steel products, it is easy to leak water on the links, which is not conducive to the overall safety of the project; [0004] 2. When the flange made of glass fiber reinforced plastic is connected with the steel flange, no matter the service life or the quality of use, it is inferior to the steel flange and cannot be used for a long time. [0005] In view of the above problems, how to link t...
