10、rd: DIN 2391, part 2,7.1981 1 Material Steel pipes to these technical delivery condiions are manufactured from the unalloyed and low-alloyed steels, mentioned in clause 6.1. The melting process, as well as the method of casting, are left to the manufacturer. In special cases, however, such details m
11、ay be agreed upon on the order (see material release). 2 Manufacturing Process The seamless steel pipes shall be manufactured from hot or cold roiled pipes by cold drawing or cold roiling. 3 Condition of Delivery and Designation Condition of delivery 3.1 Bright Drawn - Hard (BK)* (cold finished) The
12、re is no heat treatment after final cold drawing. Thus the pipes have only small capacity for deformation. They cannot be bent, flared or expanded etc. 3.2 Bright Drawn - Soft (BKW)* (lightly cold finished) After cold drawing the pipes are annealed or normalized, then lightly drawn (cold drawn). Opt
13、ionally, the pipes may be stress relieved after cold drawing. The pipes can be cold formed within certain limits with appropriate treatment (bending, flaring, expanding etc). * The data in brackets are abbreviated tens for conditions of delivery to DIN 2391, part 2.
