Notes: (1) F&D Head #1 limits the UG-99(b) stress ratio. (2) The zero degree angular position is assumed to be up, and the test liquid height is assumed to the top-most flange. The field test condition has not been investigated for the Chamber bounded by F&D Head #2 and F&D Head #1. The test temperature of 28 °C is warmer than the minimum recommended temperature of -16.1 °C so the brittle fracture provision of UG-99(h) has been met.

23 SOFTWARE FEATURES Name: COMPRESS 2014 Version: Build 7400 Manufacturer: Codeware Description: COMPRESS is an engineering productivity tool that models, calculates and creates

reports for ASME pressure vessels and heat exchangers.

For new designs, COMPRESS selects sizes, thicknesses and ratings to meet Code requirements.

For rating or turn-around projects, COMPRESS calculates the MAWP and minimum thickness

while allowing you to input your existing geometry.

Where appropriate, COMPRESS designs and rates pressure vessels and heat exchangers using

industry standard methods and good engineering practices.
