20G seamless steel pipe corrosion-resistant？
Oil and natural gas, as important energy sources for national economic development, have been valued by countries around the world. At present, the transportation of oil and natural gas resources in China mainly relies on pipelines, and the pipes are generally steel spiral welded pipes. Due to the complex terrain of the pipeline crossing area, the environment is not only spatially different, but also subject to erosion from various media over time. Especially in acidic media, pipeline corrosion is quite severe.
Alloy steel has superior performance and is currently widely used, but its cost and scale still cannot meet industrial requirements. Artificial synthetic fiberglass pipes have broader development prospects. It has excellent properties such as high strength, good toughness, corrosion resistance, and mechanical damage resistance, and is low-cost, convenient for transportation, and easy to construct and maintain.
Due to the electrochemical corrosion of hydrogen sulfide and the presence of hydrogen, the fracture toughness of pipeline steel and the physical, chemical, and mechanical properties of materials in sulfur-containing oil and gas gathering and transportation pipelines are reduced. During transportation, stress corrosion cracking and hydrogen induced cracking are prone to occur, which can damage the safety of gathering and transportation pipelines and affect their service life. Therefore, when selecting materials, special consideration should be given to the stress corrosion resistance of pipes. Developed countries in the construction of oil and gas pipelines should learn from and learn from international standards. At the same time, China should strengthen the testing and research of H2S resistant materials, and develop new and suitable H2S resistant pipes.
