?

?? Shandong shunxinda Machinery Co., Ltd. (13969559358) is located in Liaocheng Economic Development Zone, Jiangbei water city with beautiful scenery. It is a company specializing in the production, processing and sales of precision seamless pipe, cold drawn precision seamless pipe and cold-rolled precision seamless pipe

Q345B precision bright tube pipeline online repair renovation process

Due to the effect of physics, chemistry, electrochemistry and microorganism, Q345B precision bright pipe of water supply pipeline has been running for many years without excavation. The inner wall of Q345B precision bright pipe of water supply pipeline will gradually form irregular growth ring ", and it will become thicker with the increase of pipe age, which will reduce the cross-sectional area of water, reduce the water delivery capacity and seriously pollute the water quality, Pipeline leakage is serious due to lack of maintenance. The traditional reconstruction method is to excavate and lay a new water supply pipeline Q345B precision bright pipe (the old pipeline is scrapped). However, most of these over aged pipes are laid in densely populated and prosperous urban areas, and the surrounding areas of the pipelines are filled with sewage, rainwater, gas, heat, electricity, communication cables and other municipal pipelines and facilities, Some pipelines are still riding on the buildings or completely under the road, so the implementation of the reconstruction project is quite difficult. In order to solve this problem, the technology of pipeline renewal without excavation emerges as the times require. Due to the advantages of small construction site and simple construction, the technology is widely used.

? The trenchless technology of Q345B precision bright pipe first emerged in the oil and gas industry, mainly used for the renovation and repair of oil and gas pipelines, and then gradually applied to the renovation and reconstruction of sewage pipe and water supply pipe, and rapidly promoted with the application of new pipe materials such as PE pipe. The main processes are: 1) pipeline online repair and renovation process. Comparison and summary of on-line trenchless laying and renewal technology for Q345B precision bright pipe of water supply pipeline network is an important part of water supply system. On the one hand, because of the physical, chemical, electrochemical, microbial and other functions, the Q345B precision bright pipe of water supply pipeline will gradually form an irregular growth ring along the inner wall of the pipe. "With the growth of the pipe age, the water cross-section is reduced, the water delivery capacity is reduced, and the water quality is seriously polluted; In addition, with the rapid development of the city, the scale of water supply network is also expanding. Many water supply pipelines Q345B precision bright pipes have been laid for a long time, and the leakage is serious due to lack of maintenance; Therefore, it is necessary to improve the water quality, reduce the leakage and increase the discharge capacity of Q345B water supply pipeline. The traditional reconstruction technology is to excavate and lay a new water supply pipeline Q345B precision bright pipe, and report the waste water supply pipeline Q345B precision bright pipe. Because most of these over aged pipes are laid in densely populated and prosperous urban areas, the surrounding areas of the pipelines are filled with sewage, rainwater, gas, heat, electricity, telecommunication cables and other municipal pipelines and facilities. Some of the pipelines are also under the pressure of buildings. Moreover, due to the widening of main roads, some sections of pipelines are completely under the road. If the excavation method is adopted, in addition to the need for a large area of construction site, the dense urban area is bound to bring about traffic, surrounding environment and people's daily life
