Calibrated round pipes

Manufactured from sheets or metal plates that are rolled into pipes and welded along the connecting line. The connection must be for the whole length of the pipe (strictly parallel to the pipe axis profile) or along spiral (more rarely). Construction pipes are often used in mechanical engineering, namely manufacturing of ships, automobiles and wagons. Pipes of this class are used for production of cranes, poles, bearings and constructive elements, including even furniture. The constructions are manufactured according to standard EN10219, steel grade S235JRH, S355J2H and calibrated according to standard EN10305-3, steel grade DC01, E190, E195, DD11 (pickled).

According to standard EN10219, steel grade S235JRH, S355J2H.
