Description

Seamless precision steel tube made from St 30 Al is mainly used as construction element with special requirements in dimension accuracy, small wall thicknesses and good surface condition. The tubes are made in different grades (A and C). Grade C is valid for conduits. Grade A: for mechanical load without special grade requirement, without inspection certificate Grade C: for special requirements (testing after arrangement, e.g. bending, flanging, bulging a.o.) The weldability is given. Application (acc. VdTÜV-Wbl 445 : 2001-09): pressure vessels acc. TRB 100 and AD-Merkblatt W 4 from -10 to 300 degrees C, for steam boilers acc. TRD 702, for tube parts acc. TRbF 131 and 212 analogical St 37.0 in DIN 1629 as well as in the nuclear engineering.
