Stress Analysis of piping system (Caesar II)

Updated: Mar 11

CAESAR II is a complete pipe stress analysis software program that allow quick and accurate analysis of piping systems subjected to weight, pressure, thermal, seismic and other static and dynamic loads. It can analyze piping systems of any size or complexity.

CAESAR II is the Pipe Stress Analysis standard against which all others are measured and compared. The CAESAR II spreadsheet input technique revolutionized the way piping models are built, modified, and verified. CAESAR II was the first pipe stress program specifically designed for the PC environment. The interactive capabilities permit rapid evaluation of both input and output, thereby melding seamlessly into the "design - analyze" iteration cycle.


Columns or Towers, used for distilling raw materials (Crude Oils) are very important equipment in any process industry. Every process piping industry must have number of columns. Pipe lines of various diameter and properties (Process Parameters) are connected to Columns at different elevations/heights. Stress analysis of all large bore lines connected to the column is required to measure proper supporting and nozzle loading. Looking at the construction of the column, it has a number of trays at different elevations. The temperature at each tray location differs based on the process. Caesar II is generally used for stress analysis of Column Piping.


CAESAR II incorporates a wide range of capabilities, from numerous piping codes, to expansion joint, valve and flange and structural data bases, to structural and buried pipe modeling, to equipment and vessel nozzle evaluation, to spectrum and time history analysis. Most of the features of CAESAR II are available at a keystroke, but at the same time are not imposed upon the analyst.


Customization options are available in CAESAR II. It can be driven by user requests, code changes, and the need to benchmark older, existing systems and their initial design. Many of these customization options enable newer analysis techniques appearing in current literature.


INPUT DATA

We can Easily input the data to CAESAR II. CAESAR II can display all required data correctly for a piping system analysis model. Input can be accessed or modified on an element-by-element basis, or datasets can be selected to make global changes.


CUTTING-EDGE GRAPHICS

The CAESAR II input graphics module makes quick work of developing analysis models while clearly indicating areas of concern and providing an excellent idea of the piping system's flexibility. Stress models with Color-codes and animated displacements for any stress load case are available.


WIZARDS AND TOOLS

For creating expansion loops or viewing plant models in the analysis space, tools and wizards are there. It helps to bridge the gap between knowledge and experience. Such tools take the guess work out of producing accurate analysis. It also recommends practical design changes.


OPTION FOR ANALYSIS

CAESAR II analyzes the effects of wind, support settlement, seismic loads and wave loads besides the evaluation of a piping system's response to thermal, deadweight and pressure loads. Nonlinear effects such as support lift off, gap closure and friction are also included. CAESAR II also selects the proper springs for supporting systems with large vertical deflections. Dynamic analysis capabilities include modal, harmonic, response spectrum and time history analysis.


ERROR CHECKING AND REPORTS

It includes an integrated error checker. This error checker analyzes the user input and checks for consistency from both a "finite element" and "piping" point of view. Reports are clear, accurate concise and fully user definable.


MATERIAL AND ASSEMBLIES DATABASES

CAESAR II incorporates table look-ups for piping materials and components plus expansion joints, structural steel sections, spring hangers and material properties including allowable stress. This ensures correct datasets are used for each analysis. CAESAR II comes complete with major international piping codes.


BI-DIRECTIONAL INTERFACE WITH DESIGN

CAESAR II incorporates the industry's first and only seamless, bi-directional link between CAD plant design and engineering analysis.
