PRODUCT SUMMARY:


CodeCalc analyzes all of the individual components of a typical pressure vessel or heat exchanger, including shells, heads, legs, lugs, nozzles (with strength path calculations), cones, floating heads, tubesheets (both TEMA and ASME) and flanges.


Zick analysis, WRC 107, and calculations for legs and lugs are also included.   Dimensional input data can be quickly checked by reviewing a simultaneous dimensioned sketch of the component. 

Output lists the equations used to solve for the important results and has extensive reference to the standard used for the calculation. Having been around since 1987, CodeCalc maintains its popularity today because of its range of applications, user-friendliness, economy, reliability and our unparalleled technical support.


COMPONENTS ANALYZED

Shells & Heads - under internal or external pressure, calculate the maximum allowable working pressure (MAWP) or the required thickness for a specified working pressure.

Conical Sections - under internal or external pressure, calculate the maximum allowable working pressure, the thickness required for a specified working pressure and the discontinuity stresses at cone-to-cylinder junctures.

Nozzles - under internal or external pressure, calculate the area of replacement, minimum design metal temperature, mimimum neck thickness, weld strength, minimum weld size and large nozzle and hillside calculations.

Flanges - calculate the required thickness, MAWP and code-defined stresses for virtually any geometry.  Included are ASME Section VIII Appendicies 2 and Y (stress calculations) and Appendix S (rigidity calculations).

Fabricated Piping Intersections - (ANSI B31.3), calculate the required thickness due to internal pressure, required & available area of reinforcement and MAWP.

Base Rings - calculate the required thickness of the gussest, skirt and annular baseplates due to wind or seismic moments and the local stress and required thickness of the top plate.

Large Openings in Flat Heads - calculate the stresses and allowables based on ASME Section VIII, Division 1, Appendicies 2 and 14.

Half-Pipe Jackets - on cylindrical shells, calculate the required thickness and maximum allowable working pressure based on ASME Section VIII, Division 1, Appendix EE.

Tubesheets - and flanged extension, calculate the required thickness using TEMA or ASME methods.  You can determine allowable tube stresses, tube-to-tubesheet joint loads and allowable loads.

Nozzle Loads - calculate local stresses due to external loads according to WRC bulletins 107 and 297, as well as PD5500 Appendix G.  Allowable stresses are also computed.

Horizontal Vessels - under pressure on saddle points, calculate the stresses (using Zick Analysis) at important points on the vessel and saddles for various conditions including wind and seismic loads.

Vessel Attachments - calculate stresses on legs, supporting lugs and lifting lugs, including their allowable limits.  Also calculate stresses on cap type and continuous top support rings (girder rings).

Flanged & Flued Expansion Joints - calculate the stress, cycle life and spring rate in accordance with ASME Section VIII, Division 1 and TEMA Standards.

Metal Bellows Expansion Joints - calculate the stress and cycle life for both reinforced and non-reinforced bellows per ASME Section VIII, Division 1, Appendix 26.

Rectangular and non-circular vessels - calculate the MAWP and stress, including stayed or reinforced geometry, per ASME Section VIII, Division 1, Appendix 14.

Floating Heads - under internal and external pressure, calculate the required head thickness and resulting flange bending moments per ASME Section VIII, Division 1, Appendix 1.
