Damage to the pipeline prevents construction workers from moving the pipeline in a dragged manner
Technical measures for glass fiber reinforced plastic pipeline construction, pipeline connection technical measures In order to ensure the tight connection during the installation of glass fiber reinforced plastic pipes, the following technical measures can be taken: to clean the thread surface, and to remove the grease at the pipeline interface during installation to prevent corrosion of the rubber ring. According to different regions and temperature conditions, determine the curing time of the adhesive according to the requirements. Especially in the northern areas of China, low temperature is often easy to cause the failure of the adhesive. So in the colder areas, the adhesive should be heated so that it can be fixed quickly and ensure that the pipe connection has good sealing.
Technical measures for trench excavation and pipeline installation FRP pipelines should be protected during transportation, and pipelines should be inspected to ensure that there is no damage when they arrive at the construction site. Put the tested pipeline on the flat ground or pipe rack to ensure the safety of the pipeline at the construction site. If the pipeline cannot be immediately installed and the pipeline needs to be preserved for a period of time, then the pipeline needs to be covered with canvas to prevent the sunlight from decomposing it.
The main point of trench excavation is whether the bottom of the trench can be even and flat. Once the bottom of the trench has not reached a sufficient level of flatness, the pipeline is unevenly stressed when it is placed in the trench, and it is easy to break. Moreover, the sharp stones at the bottom of the trench should be cleaned to prevent damage to the pipeline when the pipe is dropped, and at the same time, the construction personnel must be prevented from moving the pipeline by dragging. Before lowering the pipe, the pipe should be placed on the side of the trench that is not filled with soil, and should be close to the trench to reduce the amount of re-handling.
