Steel Tube Handbook - 2018

1 Dear business partners, ladies and gentlemen this technical manual we prepared to contribute to the further development of our mutually good business relationships. The guide contains technical specifications for steel tubes and tubular semi-finished products produced in group companies of Železiarne Podbrezová Group. Technical details are the content of national or transnational standards and regulations, or even bilateral technical and delivery regulations or specifications. Products made out of tubes must at the same time meet the requirements of relevant laws and regulations relating to health, safety and the environment during its use. For this rea- son, the manual also gives a brief overview of standardization. Important warning: In the countries of European Union the European standards (EN) were implemented (taken) into the system of national standards. The original standards are already invalid. Therefore, in business the original standards of individual countries should not be used anymore, but valid EN standards. Data from the original standards mentioned in overviews serve during the transitional period for the possibility of comparing individual parameters in the study of older technical documentation when examining the possibility of substituting the tubes supplied and under the original standards. GOST standards, U.S. standards (ASTM, ASME, ANSI, API) and JIS remain valid.
