Pressure Vessel and Custom Flange Design Services using COMPRESS Codeware

Providing Advanced Pressure Vessel and Custom Flange Analysis for Clients Globally.

EngRx offers advanced Pressure vessel design, analysis, reverse engineering, and rating using industry recognized software. Our COMPRESS Codeware software capabilities allow for efficient pressure vessel design and engineering that reduces engineering hours while improving reliability and reducing errors.

COMPRESS Codeware, is a mainstay in engineering software specially formulated to design and analyze pressure vessels to ASME VIII-Rules for Construction of Pressure Vessels. COMPRESS Codeware can be used to rate pressure vessel designs for storage tanks, boilers, heat exchangers, and process vessels, as well as other systems designed to ASME VIII-1 or 2.

Custom Flange Design:

EngRx uses COMPRESS Codeware to design and rate custom flanges for your next project.

When Standard ASME B16.5 and 16.47 rated flanges will not meet your applications requirements EngRx will design custom ASME Appendix 2 flange configurations to best suit your needs. COMPRESS Codeware aids in the design of appendix 2 flanges with a flange design wizard which makes flange design quick and dependable as opposed to the typically engineering hours intense work of flange design. COMPRESS Codeware can also be used for modification to existing ASME B16.5 and 16.47 flanges, such as reductions in thickness, diameter or increase in bolting size.

Additional Consideration of COMPRESS Codeware for Effective Reliable Flange Design:

  • Custom designed flange pairs with mating flange bolt loads designed in accordance with ASME VIII-1, Appendix 2-5(a)(2) for your heat exchangers or other pressure vessel applications
  • Bolting loads from gasket seating
  • Appendix 2 Flange maximum allowable working pressure iterations
  • External Flange Loadings and Piping Loads. COMPRESS Codeware allows for the consideration of additional applied external loadings
    • Wind and Seismic Loadings on Appendix 2 Flanges
    • Gravity forces on Appendix 2 Flanges from supported weight
    • User specified forces and moments.
    • UG-44 external loadings on B16.5/16.47 rated flanges
  • Discontinuity stresses calculations for Flanges without knuckles or flare radii
  • UG-44 external loadings on B16.5/16.47 rated flanges
  • Bolted Joint Analysis per ASME PCC-1 Appendix O using simple approach to determine bolt stress based on target gasket stress or the joint approach which considers gasket seating stress, gasket compressive strength, bolt allowable stress and flange allowable stress
  • Custom ASME VIII-1, Appendix Y Flanges
  • UG-34 Bolted Covers, designed to accommodate B16.5/16.47 rated flanges or Custom designed Appendix 2 or Appendix Y Flanges

COMPRESS Codeware Aided FEA Analysis:

Some applications can require the use of additional special FEA analysis on custom flanges in accordance with U-2(g). EngRx is more than capable of supporting these application with years of expertise in FEA analysis, made even simpler and more cost effective with COMPRESS Codeware instant 3D modeling. This allows for quick solid models that can then be exported into ANSYS FEA Software and be used to conduct special FEA analysis by EngRx. This removes front end work of labour intense modeling and eliminates potential for errors.

WRC 107 and WRC 537 to Analyze ASME VIII-1, UG-22 Pipping Loads on Nozzles and Flanges:

COMPRESS Codeware has the added capability to analyze ASME VIII-1, UG-22 Pipping Loads using the methods of Welding Research Council Bulletins 107 and 537 for local stresses in spherical and cylindrical shells. This analysis can be used to quickly and effectively iterate nozzle and flange design based on analysis results.

UG-44 to Analyze ASME VIII-1, UG-22 Pipping Loads on B16.5/16.47 Rated Flanges:

COMPRESS Codeware can effectively utilize the methods outlined in UG-44 to analyze ASME VIII-1, UG-22 Pipping loads on B16.5/16.47 rated flanges, implementing a Moment Correction factor which produced more economical designs then those produced by WRC 537.

Using COMPRESS Codeware and other engineering resources, EngRx can provide your company with complete engineering design calculations, construction and assembly drawings, solid models of assemblies and components and design registration for your ASME VIII-1 or ASME VIII-2 projects.
