Inspection method for manufacturing of steel pipes, involves manufacturing tube from steel with tube wall strength, whose multiplication with determined yield strength does not fall below certain factor as test limit value

摘要

The method involves determining the yield strength of the steel. The tube are manufactured from the steel with a tube wall strength, whose multiplication with the determined yield strength does not fall below a certain factor as a test limit value. The yield strength is determined, which the steel exhibits after manufacturing as pipe, using a measurement of the yield strength sample of the steel.
