Smarter Pressure Vessel Software

COMPRESS is an expert system that produces professional level pressure vessel design reports with a single button click.  It saves engineering hours while reducing errors and omissions.  COMPRESS checks your inputs and makes design recommendations.  This makes it the perfect solution for companies that want to bring their design work in-house.  COMPRESS automates jobs that less capable solutions require you to do.  Tasks such as compiling reports, determining MDMT chart assignments, calculating hillside nozzle intersections and liquid static head determinations are handled for you.  Features like solid modeling, drawings, material schemes, lift lugs, clips, and estimating come standard with COMPRESS.  We’ve recently introduced Advanced Report Formatting, a feature that improves the appearance of COMPRESS reports and makes them the easiest to read pressure vessel design reports available.

We invite you to review the capabilities featured below and see why COMPRESS has set the standard in pressure vessel software for over 37 years.
