Did you know that AutoPIPE can automatically create a custom isometric for your CAD Designer, Structural Engineer, Contractor or Consultant? StressIso generates a fully (customizable) dimensioned

digital stress isometric for the CAD Designer, Contractor or Client complete with the Engineer’s comments, detailed stress and support data, reference equipment like pumps or steelwork and support CAD tags.

This digital stress isometric can be reviewed and commented on in Bentley View, MicroStation, AutoCAD, or other 3rd party programs.

Current EPC Workflow Experience “A manual approach to managing these piping loads begins with analysis of the

piping system to locate supports, guides, & anchor points.

After the analysis is complete the piping engineer sorts through the piping support reactions to find the critical cases that the supports/ structure must be designed for.

These forces are hand marked on a multiple piping isometric drawings; with one copy given to the piping designer to complete the PDS piping model, locations of pipe shoes, guides, anchor points, etc; and Another copy given to the structural engineer for designing the supporting structures.

While working in PDS / FrameWorks the structural engineer would build the structural model incorporating all the required pipe supports. To prepare the structural model for analysis the engineer must then search each isometric finding the support points and associated loads evaluate and apply them to the structural model. “

“The biggest problem here is that a single process structure may have hundreds or thousands of piping isometric drawings associated with it, resulting in a vast amount of paper and manual evaluation. This is very inefficient and time consuming.”

Problem Is Consistent Across The Plant Market

• EPC # 2 – “There are some significant disconnects between the pipe stress and the structural engineers. When conveying information from pipe stress to Structural, we typically provide the preliminary structural steel drawings to pipe stress for them to mark up loads on it. This is extremely inefficient. Also, piping should try to get as much structural steel put onto the steel drawings so that detailing, fabrication and erection can be done in a single pass”

• EPC # 3 – We have some serious frustrations in the way piping designers do their work, interfacing with structural and mechanical. I know the current process is disjointed, but it is all our tools provide us.”

• EPC #4 - We have standard loadings that take care of the major stuff. The thing that is a killer is the special case stuff. The thermal loads and piping movements, spring supports, anchor points etc; these types of things have special details, as well as high loads. In addition, a structural engineer can’t guess where these things are going to be or what they will look like. This has to come from the Piping Engineer and we have to sort through drawings. Most of the time this info gets to structural at best just before you issue the drawings. Sometimes it is after the first fabrication release has been sent out and you have to revise the drawings.

Typical WorkFlow Current Approach

Pipe Stress Analysis Completed and Ready for Documentation 1. Multiple Isometric screen captures/plots are

generated 2. Critical design cases are identified and

enveloped 3. Screen captures are then marked-up with the

final design information such as PIPE IDs, Ratings, Elevations, Loads (local, global, type), Supports, Guides, Anchor Points, etc

4. Multiple isometrics w/similar design information is created for piping designer, structural engineer, equipment vendors, etc

5. SE needs to search and interpret each marked-up isometric and translate the support reactions into equivalent load cases for the structural model. Multiple pipe models are possible

6. {Considerable Amount Of Isometrics, Paper, & Manual Evaluation Producing a Very Inefficient & Time Consuming Workflow.}

StressIso Approach Pipe Stress Analysis Completed and Ready for Documentation 1. Multiple Stress Isometric plot are

generated automatically 2. All load cases and combinations can

be shown or filtered 3. Final design information such as PIPE

IDs, Ratings, Elevations, Loads (local, global, type), Supports, Guides, Anchor Points, are generated automatically and included

4. Multiple isometrics w/similar design information can be created for piping designer, structural engineer, equipment vendors, etc

5. SE effort no longer required** 6. Electronic Isometric generated DXF,

DWG, or DGN file available for review & markup.
