Određivanje sile vučenja kod hladnog vučenja čeličnih cijevi

The cold flow line was determined for three grades of steel pipe C.1212, C.3100 and C.1402 by the tensile test method with an undeformed sample (by M. Rheile). Tensile stress for steel pipe cold drawing without a plug, with a floating plug and with a long plug was measured by a extension belt measuring transducer. On the basis of the test results tensile stress analytical expression were determined for each grade of steel and each steel pipe cold drawing method. The analytical expression are simple and easily applicable and their results are within satisfactory limits for a production plant.
