Dear customers, dear ladies and gentlemen,we prepare this technical tube guide with the wiew of continual development of our firm mutual business relations. Tube guide includestechnical data of steel tubes and tube semi-products, made in company eleziarne Podbrezov. Technical data are included in nationaland worl-wide standards or regulations, or bilateral technical delivery conditions and terms.Application of tube products have to be in compliance with particular law and rules, concerning safety, healt protection andenvironment. For this reason is short standardisation survey listed in handbook.Attention:In the countries of European Union there were European standards (EN) adapted into the system of national standards. Previousstandards are not valid by now. Previous standards should not be used in commercial communication for this reason, but validEN standards.Data from previous standards, shown in surveys, during temporary period support the comparison of individual tube parameters,older technical documentation study, possible tube alternative to previous standards finding e.t.c.GOST, USA (ASTM,ASME, ANSI,API ) and JIS standards are still valid.

Committee for standardization and standard

International, worldwide recognized actual standardsare issued by two standardization institutions residentin Geneva:

ISO (International Standards Organization) issu-ing universal standardsIEC (International Electrotechnical Commision) is-suing electrotechnic standards

ISO standards are accepted worldwide and therefore they usu-ally do not go trough the national standard systems. For steeltube they are applied rarely. ISO numbers are in brackets.

European standardizationEuropean standardization is analogous to global system, but it con-sist of three committees. Two first resident in Brusel, the third one inSophia Antipolis (France):

CEN (Comit Europen de Normalisation) issuesuniversal standards. Standards regarding iron and steel areisuued by European Commision for Standardization of Ironand Steel (ECISS) and appropriate Technical Committees.CENELEC (Comit Europen de Normalisation lec-trotechnique) issues electrotechnic standardsETSI (European Telecomunications Standards Insti-tute) issues telecommunication standards

National committee for standardizationThey issue national standards. Connecting to European Unionenlarging are European standards (EN) implemented into thenational standard systems (technical standard harmonization).Unlike ISO standards are EN implemented without modificationand hereby all discordant national standards have to be can-celled. Connected with this the philosophy of standard use hasessentially changed: in the past was performance of standardregulations obligatory. At present appear two terms: relevanceand obligation of standard. The standard is valid but, except someclauses, its observance is not compulsory. Standard gives recom-mend technical terms, wich need not be applied. On the otherhand two factors arise: if the standard is specific in the contract between seller and

buyer, it will become a part of contract and all its demandshave to be executed

in the case some damage occures in consequence of failureof harmonized standard claims, he who failed terms, definedby gowernment act, bear liability. Thats because by law ifnational standard system assumes harmonized EN, it will be-come also harmonized. After publishing in Official publica-tion of national standards standard may be used for advise-ment of technical terms execution.

Another standardsHere belong mainly company standards. These can not be con-trary to national standards.Further class are the standards of craft companies, e.g. in USA(AISI, ASTM, ASME, API, SAE).Valid bilateral technical terms or specifications can be shut-downbetween commercial partners.

Technical standardsare a part of legislation valid in appropriate industrial field.Specific connection of particular regulations is shown in thecapters of individual tube range.

Steel tubes classification and terminology

Mentioned terms of steel tubes are in standard EN 10079 or others(ISO 6929).Tube classification goes out several aspects: mode of produc-tion, cross section shape, tube ends treatment, sphere of tube usage.Ac
