European Standard and Russian Standard for Submerged Arc Welded Steel Pipe: Technical Specification and Application Comparison
Submerged arc welded steel pipes are widely used in the fields of oil and natural gas transportation, and their European standards (European standards) and Russian standards (Russian standards) provide important technical basis for the production and quality control of steel pipes. The European standard is mainly based on the EN 10217 series standard, which covers submerged arc welded steel pipes of different grades and specifications, and specifies the detailed requirements for the size, shape, wall thickness, chemical composition and mechanical properties of steel pipes. EN 10217 standard emphasizes the corrosion resistance and welding quality of steel pipes to ensure the long-term stable operation of pipelines in complex environments. For example, the EN 10217-2 standard specifies the specific indexes of chemical composition and mechanical properties of welded steel pipes made of non-alloy and fine-grained steel, such as yield strength, tensile strength and elongation, so as to meet the requirements of different projects for steel pipe properties.
Russian standards are mainly based on GOST 10704-91 and GOST 20295-85. GOST 10704-91 standard stipulates the technical requirements of longitudinal submerged arc welded steel pipe, including the size, tolerance, surface quality and welding technology of steel pipe. The standard has strict requirements on welding heat input of steel pipe and chemical composition content in weld metal to ensure the microstructure and mechanical properties of weld. GOST 20295-85 standard is applicable to welded steel pipes for oil and natural gas transportation, and specifies the manufacturing process, quality control and testing methods of steel pipes in detail. Russian standard also pays special attention to the low-temperature performance of steel pipes, so as to adapt to the special environmental conditions in cold regions of Russia and ensure the safe operation of pipelines in low-temperature environment.
These standards provide comprehensive technical guidance for the production and application of submerged arc welded steel pipes, and ensure the safe and stable operation of pipelines in various complex environments. By strictly following the European and Russian standards, manufacturers can produce submerged arc welded steel pipes that meet the international quality requirements and meet the high standard requirements of oil and gas pipelines in different countries and regions. At the same time, these standards also provide an important reference for the design, construction and maintenance of pipelines, and promote the healthy development of oil and gas transportation industry.
