StE210.7 Seamless pipes
A)Untreated ,after a hot forming operation by rolling,pressing or drawing, on condition that said hot forming operation achieves an irreproachable structure condition with adequate uniformity without any further treatment
B)Normalized cold rolled or cold drawn pipes must be normalized in every case.
StE210.7 Welded pipes
A)Pipes welded from normalized and subsequently cold curved plate or strip no further heat treatment
B)Pipes welded from normalized and subsequently hot curved plate or strip under controlled temperature
C)In the case of electrically pressure welded pipes which are not normalized around the entire periphery ,an annealing of the weld must be carried out in order to achieve as uniform as possible a distribution of the strength properties.
