摘要
The production process uses martensite steels with chrome content 9-12%. The pipe wall register (2) for the pipe wall (1) of pipes (3, 3.1) is produced by connecting the pipes and webs (4) by weld seams and receivers by weld seams to the registers. Initial heat treatment of the weld seams takes place in the workshop. Further assembly welding takes place, followed by more heat treatment of the seams, them final assembly welding with shells fitted.
