Dear Sirs,

Please find attached zip file with two calculation of big nozzle on torispherical head with EN 13445.
The construction and all size are same.
One calculation made with PVElite 2018 which has no result see Result 2018.
The second calculation with PVElite 2017, which has result.

Is it an error in PVE 2018 ?

Result 2018:
Note:
The Nozzle + credit limit or Reinforcing Pad is outside the Spherical Diameter Limit!
As the head thickness is required to account for this, the pressure/area calculation
is not required. Refer to 7.7.2 of EN-13445 and paragraph 9.1 of EN-13445.

The Drop for this Nozzle is : 140.6306 mm
The Cut Length for this Nozzle is, Drop + Ho + H + T : 386.8109 mm

For possible nozzle interference - See Nozzle Summary


Warning: PMax was zero. Local load calculations not possible.

Best Regards
Gabor Szabados
