This package is for use with Microsoft Excel 2010 and later. Files contain VBA macros.

  1. Calculators per ASME B31.3 -2022, Process Piping:
    1. Allowable Pressures of Pipe & Tube (para. 304.1)
    2. Hydrostatic and Pneumatic Leak Testing, Dimensional Properties (file added Dec. 19, 2018)
    3. Required Thicknesses of Pipe & Tube (para. 304.1)
    4. Reinforcement of Welded Branch Connections (two files):
      1. One file allows design of individual branches and can check for overlapping reinforcement zones.
      2. Another file has a table w/ up to 190 branches.
    5. Reinforcement of Extruded Outlet Pipe Branch
    6. Reinforcement of Extruded Outlet Tapping Tee (Split, Welded, Complete Encirclement)
    7. Pipe Bending Required Thickness and Allowable Pressure
    8. Mitered Elbow Required Thickness and Allowable Pressure
    9. Integrally Reinforced Branch Outlet Fitting (ref. MSS SP-97)
    10. Line Blanks, Line Spacers, Spectacle Blinds (Fig-8's), and Restricting Orifices.
    11. Material and Dimensional Properties of Pipe and Tube (Dimensions, Stresses, Young's Modulus, Thermal Expansion, weights, UNS numbers)
    12. Chapter IX High Pressure -- Allowable Pressures of Pipe & Tube

User Licenses:

Single User License: For use only by 1 person.

Multiuser License: If there are 3 or more users, including with access on a network and/or intranet, then the price would be 3 times single user price. Just enter 3 at checkout and get 1 download link in email.

For security, the individual or IT department should prepare a new folder which will contain extracted files. This folder would be copied to single users or made network accessible to all assigned multiusers, as applicable.

Security settings for the folder will likely show as blocked initally, which is good for testing on a standalone computer. (Search for Microsoft's various instructions for blocking or unblocking a folder or single file.).

Media & Delivery: The preferred method of delivery is a zipped file by download link. If requested, I can send files by attachments with separate e-mails.

You should prepare a new folder which will contain extracted files. I suggest using a stand-alone computer for security testing. Security settings for the folder will likely show as having macros blocked. If files are blocked, then to unblock: follow Microsoft's various instructions for blocking or unblocking a folder or single file.

Updates & Upgrades: One free update may be requested by previous customers within the 12 months following a purchase. There is no discount offering.

Payment Methods:  You can purchase over the Internet with any major credit card, PayPal, or send check (cheque) or cash. You can send email directly to me to arrange for payment by check.
