"ASME B31.8 & Chapter VIII" Piping Code Enhancements for AutoPIPE

Note: if an enhancement or defect has not been added to the program, log an Service request for that enhancement. The more requests logged per an enhancement, the quicker the CAE development team will add that feature to the program.

The following enhancements and defects have already been requested:

Defect 681392:

B31.4/B31.8: Bend SIF value used in other code combinations may change incorrectly when the "Print" flag for Hoop stress is unchecked

Description:

B31.4 / B31.8: Bend SIF value used in other code combinations may change incorrectly when the "Print" flag for Hoop stress is unchecked. Hoop stress does not use SIF in its calculations and should not have any impact on the SIF value.

Avoidance:

Keep "Print" flag for Hoop stress checked when printing results.

Upgrade to AutoPIPE CONNECT 11.02 and higher.

Development Project: 11.02.00.xx

Enhancement 143560:

Add ASME B31.8 2014 Edition (onshore and offshore)

Description:

To introduce the 2014 edition, and associated calculation, library and online help changes, of B31.8 onshore and offshore to AutoPIPE.

Consideration:

Combined stress for restrained pipe equation was changed in this edition of the code. Paragraph 833.4 , (a) 1

Subsea structures test pressure is now 1.5 x design pressure (previously factor was only 1.4) Paragraph A847.2

Changes in App. F , Welded Branch (Intersections calculations)

F-1 (Under definition for ro, subparas. (a) and(b) revised )

Comments:

a. The test pressure factor is defined by the user on the Hydrotest Load Properties dialog. The default value displayed for the factor may however be updated for different codes. Logged new Enhancement, TFS-E291223, Set default value of Hydrotest pressure factor based on the code selected.

b. Appendix F relates to reinforcement calculations, which AutoPIPE does not perform.

Development Project: 9.6.3

Enhancement 138720:

Add ASME B31.8 2012 piping code

Development Project: 9.6.0
