Two (2) Nuclear piping codes are added as given below. Refer Piping Code Compliance section of CAEPIPE Code Compliance Manual for details.

• ASME Section III, NC - Class 2 (2017)

• ASME Section III, ND - Class 3 (2017)

New module added to evaluate Hollow Circular Attachment (Lug) and Solid Rectangular Attachment (Lug) welded to Pipe as per the following Nuclear and European codes. Refer Technical Reference Manual and Code Compliance Manual for details on implementation. This module can be accessed through Main Frame > File > New > Lug Evaluation. Download Tutorial from here.

• ASME Section III, Division 1, 2010 - NC

• ASME Section III, Division 1, 2010 - ND

• EN 13480-3 (2017) - Section 11

New module added to calculate local shell stresses as per WRC Bulletin 537 and evaluate those stresses as per ASME Section VIII, Division 2 for Nozzles attached to Cylindrical and Spherical Vessels. Refer Technical Reference Manual and Code Compliance Manual for details on implementation. This module can be accessed through Main Frame > File > New > Nozzle Evaluation. Download Tutorial from here.

For Refrigeration Piping Code ASME B31.5, the feature Show/Hide "Operating Stress for NDE" is modified to Show/Hide "Operating Stress for Impact Test" calculated in accordance with Para. 523.2.2 (f)(4) of B31.5 (2016) code.

For Piping Code = EN13480, Stress Intensification Factors (SIFs) are now calculated using Table H.3 of EN 13480-3 (2017) instead of Table H.1. Accordingly, the Code Compliance Manual is now updated to include SIFs as per Table H.3.

For Piping Code = EN13480, Settlement evaluation as per EN 13480-3 (2017) is now included in the Code Compliance. Refer Code Compliance Manual for more details.

For Piping Code = EN13480, Buried Portion of Piping Stresses are now evaluated as per EN 13480-6 (2017) in Code Compliance. Refer Code Compliance Manual for more details.

CAEPIPE can now import neutral files generated from CAESAR II versions up to and including 10.0 (CAESAR II 2018).

New feature added to print Flexibility Factors in Element forces results of CAEPIPE. This feature is not available for CSV and TEXT file outputs.

New feature added to show Signed Forces and/or Moments with Maximum Absolute Magnitude under Support Loads for Time History Load results. This can be accessed through Results Window > Results > Results... > Time History > Support Loads.

New Material Type "CI: Cast Iron" is added in Material Input and Material Library Input.

In Centre of Gravity (COG) Report, "Additional Weight" is now excluded from "Empty Weight" and shown as a separate line item.

For Piping Code = NONE, CAEPIPE internally always uses "Algebraic Sum" for Static Seismic Combination. Hence, the Static Seismic Combination is set to "Algebraic sum" by default and is disabled for user to modify.

Starting CAEPIPE Version 9.00, a new CAEPIPE Review module is made available free of any license fees and can be downloaded from here. This module can be used to read, review, print, and plot CAEPIPE models of any size and their results. This module can also be used to import and review CAESAR II input neutral files as well as PipePak input neutral files.

CAEPIPE Verification Manual, Code Compliance Manual, Technical Reference Manual and User's Manual have been enhanced and updated to be in line with software version 9.00. These Manuals can be downloaded from here.

Bug Correction: For Piping Code = B31.1, B31.3 and B31.5, Pressure Coefficient "Y" was set to 0.0 for Carbon Steel. Starting Version 9.00, Pressure Coefficient "Y" is set to 0.4 for Carbon Steel and 0.0 for Cast Iron. Refer Code Compliance Manual for details on implementation of Pressure Coefficient "Y" for different codes.

Bug Correction: Axial forces developed in Tie Rods with Gap defined were not calculated properly. This bug exists in all versions of CAEPIPE up to V8.0.

Bug Correction: For Time History loading, CAEPIPE was not displaying the "Moment" value properly for "Rotational Skewed Restraint" seen through Results Window > Results > Results... > Time History > Support Loads.

Bug Correction: "Additional Weight" was not added properly to the "Empty Weight" in Centre of Gravity (COG) report.

Bug Correction: Specified Displacement entered in Local Coordinate System (LCS) with Anchor defined in Global Coordinate System (GCS) was not printing the Anchor Loads properly.

Bug Correction: Title for Element forces in GCS was printed wrongly as "Pipe forces (local)" in Table of Contents.

Correction in Documentation: The Option "Refine Element at Branches" in the software inserts additional Nodes in Run and in Branch at a distance of OD/2 from the Branch centerline-to-Run centerline intersection, where OD is the outer diameter of the run pipe. On the other hand, User Manual of CAEPIPE V8.0 had a note with this distance mentioned as OD of run pipe.

Correction in Documentation: As per B31J, when the bend angle is 90 deg and the thickness of the bend is equal to the thickness of the matching pipe, the bend flexibility factors Ki and Ko should be calculated from 1.3/h. This is not implemented in CAEPIPE software at this time. A new Note is added in CAEPIPE Code Compliance Manual to convey this to the users.
