📖 About this code
These are seamless tubes and pipes made of steel, with a circular cross-section and an external diameter not exceeding 168.3 mm. They are specifically for applications where the carbon equivalent value is below 0.86, as determined by IIW standards, often used in specialized engineering and construction.
