Publish Time: 2025-01-28
As an important part of the modern urban underground pipeline network, steel pipe direct-buried pipe undertakes the key task of conveying fluid media. Under extreme climatic conditions, such as severe cold, heat, strong wind, heavy rain, etc., the stability and durability of steel pipe direct-buried pipe face severe tests. To ensure its safe and efficient operation, it is necessary to provide comprehensive guarantees from multiple aspects such as design, material selection, construction and maintenance.In the design stage, steel pipe direct-buried pipe needs to fully consider the stress changes under extreme climatic conditions. By accurately calculating the thermal expansion and contraction effects of the pipeline under extreme temperature differences, the expansion joints and compensators are reasonably set to effectively absorb the deformation of the pipeline and prevent the pipeline from rupture or leakage caused by stress concentration. At the same time, for weather such as strong winds and heavy rains, it is also necessary to strengthen the wind pressure resistance and waterproof design of the pipeline to ensure the stability of the pipeline in bad weather.In terms of material selection, steel pipe direct-buried pipe needs to use high-strength, corrosion-resistant high-quality steel. These steels not only have excellent mechanical properties and can resist the erosion of the external environment, but also have good welding properties, which is convenient for connection and fixation during construction. In addition, professional anti-corrosion treatment is required for the inner and outer walls of the pipeline, such as spraying anti-corrosion coatings, hot-dip galvanizing, etc., to further improve the corrosion resistance of the pipeline.During the construction process, the installation quality of steel pipe direct-buried pipe is crucial to its stability and durability. It is necessary to strictly follow the construction drawings and specifications to ensure that the buried depth, slope, connection method, etc. of the pipeline meet the design requirements. At the same time, it is necessary to strengthen quality control and inspection during the construction process to promptly discover and deal with potential quality problems.In terms of maintenance, a complete monitoring and maintenance system for steel pipe direct-buried pipe needs to be established. Through regular inspections, online monitoring and other means, abnormal conditions of the pipeline, such as corrosion, leakage, etc., can be discovered in time, and effective repair measures can be taken. In addition, it is necessary to strengthen the insulation and anti-freezing measures of the pipeline, especially in severe cold areas, to prevent the pipeline from being damaged by ice.In summary, the stability and durability of steel pipe direct-buried pipe under extreme climatic conditions requires comprehensive consideration from multiple aspects such as design, material selection, construction and maintenance. Only by ensuring the coordination of these links can the safe and efficient operation of steel pipe direct-
