Production border dimensions of tubes (eg. tubes with thick walls) upon agreement. Other dimensions and precision tubes are produced by cold forming (cold drawing). 5. Russian standards and currently already replaced standards ČSN and STN also contain the tubes with other nominal dimensions than those listed in table. The supply of these tubes is possible by agreement. It is the outside diameter 28, 76, 89, 102, 114, 121 and 140 mm and wall thickness 2,5 / 2,8 / 3 / 3,5 / 5,5 / 6 / 6,5 / 7 / 7,5 / 8,5 / 9 / 9,5 / 12 mm. 6. Dimensions of steel tubes according to U.S. standards (Tubes and Pipe), API standards, pipes for threading and tubes and pipe supplied by Japanese standard JIS are listed in other tables of dimensions. 7. The professional literature also contains the standards ISO. For dimensions and weight of steel tubes with plain ends valid standard ISO 4200, system of tolerances is in standard ISO 5252. ISO 1129 contains dimensions, tolerances and weight of steel tubes for boilers, superheaters and heat exchangers. 8. EN standards valid for individual types and groups of steel tubes (eg. tubes for pressure equipment) also contain its own dimension table. Dimensions in them are taken from EN 10220. In the survey tables of different groups of tubes are as dimensional standards given numbers of EN valid for given group of tubes (eg. EN 10216-1). cold drawn hot rolled dimensions according to standard EN 10210-2 standard wall thickness of specific outside diameter according to DIN 2448 Tolerances depend on method of manufac- ture, steel grade and heat treatment.
