Implementation standards for straight seam welded tubes(LSAW Steel Pipe)

The implementation standards of straight seam welded pipes can vary according to different countries and regions. The following are some common implementation standards for straight seam welded pipes.

American standard

1.ASTM A53/A53M: Standard Specification for Carbon Steel Straight Seam Welded Pipe.

2.ASTM A252: Standard specification for straight seam welded pipe for steel piles.

3. ASTM A795: Standard specification for ferrite stainless steel straight seam welded pipe.

European standard

1.EN 10219-1: Requirements for cold-formed welded pipes of unalloyed and fine-grained steels for structural use.

2.EN 10255: Requirements for threaded joints for welded pipes made of non-alloy steel.

Chinese standard

1.GB/T 3091: Requirements for welded steel pipes for general structures.

2.GB/T 9711: Requirements for straight seam welded pipes for steel welded pipeline transportation systems in the oil and natural gas industry.

3.GB/T 13793: Requirements for high-frequency straight seam welded pipes for general flat products.

Japanese standard

1.JIS G 3444: Technical requirements for welded steel pipes for general structural use.

2.JIS G 3457: Technical requirements for high-pressure straight seam welded steel pipes.

3.JIS G 3466: Technical requirements for square and rectangular welded steel pipes for general structures.

These standards stipulate the requirements for materials, dimensions, processes, chemical composition, mechanical properties, inspection methods, etc. of straight seam welded pipes. Depending on specific needs, manufacturers and users can choose straight seam welded pipes that meet applicable standards.

When selecting straight seam welded pipes, it is recommended to refer to the corresponding national and international standards and further communicate with suppliers or manufacturers to ensure that the purchased pipes meet the required technical specifications and quality requirements.

Implementation standards for seamless pipe

 1. API 5L: Standard established by the American Petroleum Institute (API) for the manufacture and processing of seamless steel pipe fittings. This standard stipulates the materials, dimensions, mechanical properties, inspection methods and test conditions of pipe fittings.

2. ASME B36.10M: Standard established by the American Society of Mechanical Engineers (ASME) for the manufacture and processing of seamless steel pipe fittings. This standard stipulates the dimensions, materials, mechanical properties, inspection methods and test conditions of pipe fittings.

3.GB/T 12771: Chinese national standard for the manufacture and processing of seamless steel pipe fittings. This standard stipulates the materials, dimensions, mechanical properties, inspection methods and test conditions of pipe fittings.

4.DIN 2638: German standard for the manufacture and processing of seamless steel pipe fittings. This standard stipulates the dimensions, materials, mechanical properties, inspection methods and test conditions of pipe fittings.

5.JIS G 3454: Japanese Industrial Standard for the manufacture and processing of seamless steel pipe fittings. This standard stipulates the materials, dimensions, mechanical properties, inspection methods and test conditions of pipe fittings.

These seamless steel pipe fittings execution standards usually include the following:

1. Material requirements: The materials used for pipe fittings must meet standard requirements, such as carbon steel, alloy steel, stainless steel (stainless steel seamless pipe), etc.

2. Dimensional requirements: The dimensions of pipe fittings must comply with standard requirements, including outer diameter, inner diameter, wall thickness and other parameters.

3. Mechanical performance requirements: The mechanical properties of pipe fittings must meet standard requirements, such as tensile strength, yield strength, elongation, etc.

4. Inspection method requirements: The inspection methods of pipe fittings must comply with standard requirements, such as ultrasonic flaw detection, radiographic flaw detection, magnetic particle flaw detection, etc.

5. Test condition requirements: The test conditions of pipe fittings must comply with standard requirements, such as test temperature, test pressure, etc.
