CODECALC - Vessel, Heat Exchanger & Piping Component Analysis

Windows 2000/XP

CODECALC contains 19 routines for the design and rating of components for pressure vessels, shell & tube heat exchangers, flanges and piping. The calculations are based on the latest versions of ASME VIII, TEMA and ANSI B31.3 codes. The program now has the complete ASME II Part D database (2000+ materials). Databases are provided for pipe diameter and wall thickness for all standard pipe sizes, pressure vs temperature charts for ANSI B16.5 flanges, and section properties for AISC beam sections. HTML help is available for all data entry fields. Printout of all equations and intermediate results are available for quality inspection. A summary printout for a complete vessel or heat exchanger may be printed. Sample calculations are supplied for all modules. Version 6.2 routines are fully 32-bit , with interactive on-screen calculations, and graphical display of selected vessel components as the data is being entered. A LAN version of CODECALC is also available. All CODECALC routines are now included in PV-ELITE as well.

SHELLS - Design of cylindrical/conical/spherical vessels and exchangers to ASME. End types handled are elliptical, torispherical, flat and spherical heads. The program calculates required thickness and MAWP for the given component, for Internal and External Pressure loads. It also calculates the minimum design metal temperature per UCS-66. Stiffening rings are also considered.

NOZZLES - Required wall thickness and reinforcement under internal/external pressure for nozzles in shells and heads to ASME. The program also calculates the strength of reinforcement and evaluates weld failure paths for the nozzle.

CONICAL SECTIONS - Internal and external pressure analysis of conical sections and stiffening rings to ASME. Area of reinforcement and moment of inertia calculations are included.

HORIZONTAL VESSELS - Stress analysis of horizontal drums on saddle supports (Zick analysis). Stresses are calculated at the saddles, midpoint of the vessel, and in the heads. Stiffening rings may be included.

FLOATING HEADS - Internal and external pressure analysis of bolted dished heads (floating heads) to ASME. Soehren's technique is also implemented by the program.

FLANGES - Stress analysis and geometry selection to ASME for the following types of flanges:

Weld neck, integral, slip-on, loose (with/without hubs), ring, blind (circular/non-circular), reverse geometry, flat-faced (with full face gaskets), and TEMA channel covers.

TEMA TUBESHEETS - Analysis of all types of tubesheets using TEMA (7th Ed; A-91 Errata). Calculations are provided for tubesheets extended as flanges, and calculations for fixed tubesheets cover the effects of differential thermal expansion and the need for an expansion joint.

ASME TUBESHEETS - Determines required tubesheet thickness for fixed/U-tube exchangers (App. AA)

LEGS & LUGS - Analysis of vessel support legs, support lugs and lifting lugs. A full table of 929 AISC beams, channels and angles is included in the program.

PIPES & PADS - Required wall thickness and MAWP for two pipes, and branch reinforcement requirements for the same two pipes considered as a branch and header. (ANSI B31.3)

THIN JOINTS - Stress and life cycle evaluation for thin walled expansion joints (Appendix 26)

THICK JOINTS - Stress, life cycle, and spring rate calculations for flanged/flued expansion joints (App. CC)

 HALF PIPE JACKETS - Determines required thickness and MAWP for half-pipe jacketed vessels (App.EE)

LARGE OPENINGS - Analyses large openings in integral flat heads (Appendices 2 and 14)

RECTANGULAR VESSELS - Internal pressure calculations for rectangular, obround, and circular vessels according to Appendix 13. These include reinforced and stayed vessels.

COLUMN BASE RINGS - Stress analysis of skirts and baserings for vertical towers.

WRC107 - Local Stresses in cylindrical / spherical shells at nozzle attachments (Biljaard method)

WRC297 - Local Stresses in cylinder-to-cylinder intersections, including stresses in nozzle wall

APPENDIX Y FLANGES - Stresses in identical Class 1 flange pairs, with metal-to-metal flange contact outside of the bolt circle (App. Y)
