Method of manufacturing steam producing tube walls composed mostly of martensitic steels containing 9-12% chromium |
摘要 |
<p>#CMT# #/CMT# 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. #CMT#USE : #/CMT# For pipe walls of a steam generator. #CMT#ADVANTAGE : #/CMT# Production is more efficient and practical. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a flat pipe wall register of the steam generator pipe wall in a view showing the register in the workshop. 1 : Pipe wall 2 : Register 3, 3.1 : Pipes 4 : Webs.</p> |
