GB/T9711-2017 standard has very strict technical requirements for longitudinal submerged arc welded steel pipes, including chemical composition, mechanical properties, ultrasonic flaw detection, impact test, Tensile testing and other aspects. These requirements ensure the strength, reliability, and safety of steel pipes, which can adapt to various complex engineering environments.

GB/T9711-2017 also specifies the test methods for straight seam submerged arc steel pipes to ensure that the product quality meets the standard requirements. These tests include appearance inspection, dimension measurement, physical property test, etc. Through scientific and effective inspection means, the quality of longitudinal submerged arc welded steel pipes is guaranteed to be controllable.

In addition, the national standard for LSAW Steel Pipe GB/T9711-2017 also specifies the packaging and marking of straight seam weld steel pipes. In terms of packaging, it is required that the packaging be firm, moisture-proof, and damage proof to ensure that the product is not damaged during transportation. In terms of marking, it is required to clearly indicate the name, specification, batch and other information of the straight seam steel pipe for users and regulatory authorities to inspect.
