Construction details

Materials:The canisters were manufactured using high tensile strength materials:

  • Plate: SA 517 GrF
  • Forgings: SA592 GrF

Dimensions:

  • Overall height: 10 meters
  • Internal Diameter 1460mm
  • Shell thickness 8-10 mm

Critical aspects

  • The tolerance on internal diameter was successfully maintained within 1460mm +0.5 -0.0 mm.
  • Ovality of the assembly in free condition was achieved within 2mm.
  • Pressure test on the entire assembly was also carried out successfully at the required pressure.
