BS 3059 PART I & II
The BS 3059 standard is suitable for the manufacture of seamless steel tubes for high temperature and high pressure boilers, superhot boilers and other heat exchange equipment. It covers the following requirements:
Material of the steel pipe: The material of the steel pipe should meet the chemical composition requirements specified in the BS 3059 standard to ensure that the pipe has appropriate strength and corrosion resistance.
Steel pipe manufacturing method: Steel pipe should be manufactured by hot rolling, cold drawing or cold rolling processes to meet specific mechanical properties and surface quality requirements.
Size and tolerance of steel pipe: The outer diameter, wall thickness and length of steel pipe shall comply with the size range and tolerance requirements specified in BS 3059 standard.
Mechanical properties of steel pipe: mechanical properties such as tensile strength, yield strength, elongation and impact toughness of steel pipe should meet the standard requirements.
Steel pipe testing and inspection: Steel pipe should be subjected to various tests and inspections, such as chemical composition analysis, mechanical properties testing, non-destructive testing and appearance inspection, to ensure quality.

Finishing rolling process:
Finishing rolling is a process to obtain higher precision and better surface quality by rolling the heat-treated seamless steel pipe multiple times. The specific steps include: heat treatment - pickling - cooling - finishing rolling - sizing - cutting - length - inspection - packaging. Finishing rolling can improve the precision, surface quality and mechanical properties of steel pipe.
Cold drawing process:
Cold drawing is a process of drawing the heat-treated seamless steel pipe one by one in a cold state to obtain high precision, high surface quality and high mechanical properties. The specific steps include: heat treatment - pickling - cooling - cold drawing - deoxygenation - wet pickling - cold water washing - leveling - straightening - pickling - cold water washing - oxide skin - cold drawing - sizing - straightening - pickling - cold water washing - deoxygenation - polishing - inspection - packaging. Cold drawing can significantly improve the dimensional accuracy, surface quality and mechanical properties of steel pipes.
Hot rolling production process:
Hot rolling is the process of heating the blank to a certain temperature, and then forming it into seamless steel pipe through multiple rolls. The specific steps include: heating - rolling - roll probe - sizing - cooling - trimming - rod breaking - inspection - packaging. Hot rolling can produce seamless steel pipes with large diameters and wall thickness, but the accuracy and surface quality are not as good as fine rolling and cold drawing.
These three processes have different applications in the production of seamless precision steel pipes, and the specific choice depends on the required dimensional accuracy, surface quality and mechanical properties.
The BS 3059 standard is suitable for the manufacture of seamless steel tubes for high temperature and high pressure boilers, superhot boilers and other heat exchange equipment. It covers the following requirements:
Material of the steel pipe: The material of the steel pipe should meet the chemical composition requirements specified in the BS 3059 standard to ensure that the pipe has appropriate strength and corrosion resistance.

Size and tolerance of steel pipe: The outer diameter, wall thickness and length of steel pipe shall comply with the size range and tolerance requirements specified in BS 3059 standard.
