Pipe Stress Analysis, Design Code Compliance and the ASME B31J Document – a ‘Need to Know’ Summary


By Steve Gillott
European Sales Director, Intergraph CADWorx & Analysis Solutions

Commonly, piping networks are modelled using beam type models with the stresses and flexibilities at discontinuities (for example, branch or tee connections) being calculated using simple empirical relationships, such as those found today in ASME B31.3 Appendix D. The simple formulae found in this and other international design codes* are based upon work carried out in the mid 1900’s by a pioneer in the field A.R.C. Markl, a gentleman most respected by engineers worldwide.  The data in Appendix D and other design codes used by pipe stress engineers provides the relevant Stress Intensification Factors (SIFs) and flexibility factor (k’s) for the discontinuity at hand.  

Our knowledge, expertise and technology has developed almost exponentially over the last few decades and we now know there are many limitations in the accuracy of these formulas which, depending on the situation, can lead to either grossly over or under conservative results. Within Appendix D itself and in many other locations in the design codes, these inadequacies are acknowledged and the engineer is instructed by the code to use ‘more applicable data’ if available; see extract below.


In 2007, ASME awarded a contract to Paulin Research Group (PRG), known as the 07-02 Project, to develop this ‘more applicable data’ for use in design code calculations.

More Applicable Data
Based on results of the latest analysis, research, and testing conducted for the ASME committee in the 07-02 Project, this “more applicable data” is now widely available within the new** ASME B31J Document. This improved data is especially relevant for piping systems…….
•    With large D/T ratio
•    Containing sensitive or rotating equipment
•    In cyclic operation
•    In ‘tight’ configurations and with short or stiff thick-walled piping
•    Where the solution is dependent on the SIF for a small bore connection
•    Where torsion is significant - even though ASME B31.3 gives a torsional SIF term in the stress equations, there is no guidance on the value to use and the engineer is advised to use a value of 1.0 ‘in the absence of more directly applicable data’.
…………and many other instances.  

Application of these newer values can result in significantly lower system forces/moments and stress levels which, in turn, can result in more economical designs. For some more critical situations it can even result in more realistic stress values which are higher; this allows for a reduction of risk for failure in such cases.

B31J Document
The publication of the new** B31J document is extremely significant as:
•    It provides, for the first time, a tangible reference for the ‘more applicable data’ that the design code requires.
•    Using this data will enable pipe stress engineers to have total confidence that a given design is carried out in accordance with the intent of the code using the latest, fully tested and approved more ‘accurate’ data, without unnecessary over or under conservatism.
•    Using the better and ‘more applicable data’ helps to ensure safer systems, fewer or zero failures whilst facilitating a more efficient project workflow with fewer unnecessary system changes (i.e. to resolve problems which don’t exist in practice) – peace of mind and saving money.
•    It helps to streamline project workflows whilst ensuring safe, compliant designs

Using the ‘More Applicable Data’
Intergraph_CADWorx_Analysis_B31J_3 The relationships in B31J, whilst improving the accuracy of the analysis, can be quite complex in their application. Analysts can manually apply the data in B31J to their pipe stress analysis calculations with the associated risk of transposition errors coupled with a large increase in the time required to create a given analysis ‘model’.
However, during the 07-02 Project conducted by PRG for ASME, software called FEATools was developed which incorporates the ‘more applicable data’ as published in B31J.  FEATools seamlessly couples with CAESAR II®, the standard pipe stress analysis solution - the model is built in CAESAR II, imported into FEATools where the SIFs and k’s are updated automatically in an improved CAESAR II model.

FEATools also provides the ability to conduct accurate Finite Element calculations on each component (e.g. tee, bend, nozzle connection….) for ‘state of the art’ accuracy. The Finite Element model is created automatically using the data obtained from CAESAR II combined with the technology developed by PRG in their proprietary software; optional additional data may be provided by the engineer as required (e.g. specific bend attachment data). 

Intergraph_CADWorx_Analysis_B31J_4 This is by far the easiest and most reliable way to incorporate the ‘more applicable data’ into a piping system stress analysis as required by ASME in the code and as seen in the B31J Document. Results review is extremely easy and intuitive.  No longer does an engineer have to open multiple files, export to Excel, create side by side tables etc. in order to compare Model 1 with Model 2 to see what has changed and where.  With FEATools multiple derivatives of a given model can be viewed on graphical comparison charts to see at a glance where displacements, forces, moments or stresses have changed at all locations in the piping system.  It’s easy to see how the ‘more applicable data’ derived by FEATools has influenced and improved the CAESAR II model.

Further Refinement of Pipe Stress Models
FEATools Version 3.00 not only provides the ‘more applicable data’ in B31J but also optionally provides the pipe stress engineer with additional better data to further refine any CAESAR II analysis model with:
•    Accurate nozzle flexibility and SIF data
•    Accurate bend flexibility and SIF data (with or without attachments)
•    Allowable loads on supports (when used in conjunction with NozzlePRO)
•    Accurate API 661 nozzle data
Finally, if a given model still demonstrates non-compliance with the piping codes, any single component can be assessed separately using a ‘design by analysis’ Finite Element approach.

Safe Designs and Peace of Mind
In summary, you can use CAESAR II and FEATools to incorporate the intent of the design code and the ‘more applicable data’ in B31J. Following this workflow is quick and easy but also ensures greater accuracy without compromising designs whilst providing engineering companies with the opportunity to reduce project time scales and costs.

Owner Operators are under pressure to carry out Projects with reduced costs, maintain safety and deal with smaller margins.  The B31J ‘more applicable data’ and its implementation within CAESAR II via FEATools provides the perfect combination to achieve these objectives.

GT STRUDL Webinar: Designing and Analyzing Pipe Bridges


with Ravi Ozarker, P.E., GT STRUDL Support, Intergraph

Date: January 25, 2017
Time: 10:00 AM CT  click here for your local time
Duration: 1 hour
Cost: free eSeminar


Pipe bridges are simple truss structures that are used to support piping systems and maintenance vehicles in oil and gas facilities, petrochemical plants, fertilizer production facilities, and many other places. These bridges are commonly used to span across high points or places where existing infrastructure is in place. This could be spanning over environmentally sensitive streams or railway lines/roadways that cannot be re-routed. 

In this webinar, we'll build a 200’ maximum span long pipe bridge to connect two petrochemical facilities that are separated by railway lines. A supporting column cannot be placed on the existing railway lines. The pipes are 2’ in diameter and will be supported every 20’ as a guide support. The two pipes will have a 2’ separation and 4’ clearance from the bridge framing structure.

Using GT STRUDL, we'll create the 3D bridge geometry from scratch, use load generation features such as ASCE-7-05 wind and area loads, and install a macro to generate almost 1,000 load combinations with notional loads in a split second.

The finished bridge can be checked using AISC 14th Ed Code in GT STRUDL, and member sizes can be easily updated to produce a satisfactory design solution.

Visual Vessel Design: Allocating Newly Added Components to Existing Component Analysis

By Duncan McElrue
Senior Technical Support Engineer, Intergraph CADWorx & Analysis Solutions

Duncan McElrue

Visual Vessel Design (VVD) is a comprehensive pressure vessel, shell and tube exchanger, and boiler design and analysis software with a strong emphasis on European codes and standards.
VVD enables the explicit modeling of most vessel components. However, while building the model, the input tabbed pages of a component are filled in and the component is analyzed and saved. Any existing component in a model that could be relevant to the current component’s input may be available for selection during that input so that its pertinent information can be used in the current component analysis.

Most components’ input enable the manual entry of relevant data about neighboring or attached components that affect the current component analysis. The analysis of the component can be completed and vessel modeling can proceed.

One example of this is a jacket attachment component, ‘BR Block/Sealing Ring.’ The vessel main cylindrical shell has already been modeled and the component attached to it, but no jacket yet. Therefore, relevant details of the jacket must be manually entered:

If the main cylindrical body of the jacket is explicitly modeled at a later stage so that a complete vessel is built up, then that jacket shell component (relevant data) can be retrospectively added to the Sealing Ring component:


In fact, manually entering the jacket parameters for the Sealing Ring enables the analysis of the sealing ring to show whether or not the input jacket parameters will allow the analysis to pass and, therefore, helps design the jacket.

Another example is in fixed tubesheet heat exchanger analysis. A later added ‘EB Expansion Bellows’ component can be added (relevant data) to tubesheet input so that it can be included in the tubesheet analysis.

For example, Tubesheet input with (‘Including’) Expansion Bellows:


Yet another example is in cone to shell junction rings for ASME VIII Division 1 vessels. Later added ‘SR Stiff. Ring’ components can be added (relevant data) to Conical Shell input so that they (inertia ...) can be included in the analysis of the cone.

For example, Bottom Ring inclusion (at large base of cone):


Top Ring inclusion (at small base of cone):


Given this capability, required for complete 3D vessel modeling purposes, the design engineer can choose the extent of vessel component modeling to obtain the required analysis and deliverables for a given vessel. This is a major benefit for your workflows.

B31.3 Distribution of Information

By David Diehl
Executive Technical Director of Training, Intergraph CADWorx & Analysis Solutions

Distribution of Information

There was an interesting presentation at the ASME B31.3 Process Piping meeting in April 2016. Some commonly-used piping components, within specification, are showing very low toughness. This low toughness results in brittle failure under ambient conditions. A summary of this presentation can be found at the Chemical Engineering July 2016 Letters to the Editor. If you use A106, A53, or API 5L pipe; A234 forgings; or A105 flanges, you should read the post.

This CAESAR II article is not focused on the important message provided in the B31.3 presentation but instead on the distribution of this information. Barry Messer of Fluor Corp. presented the material which combined studies by Fluor and the Material Testing Institute.

Of course, he was interested in informing the B31.3 committee about this dangerous situation and presenting their recommendations. But the main purpose of the B31.3 presentation was a search for a means to officially “alert” to the industry either by ASME or B31.3 regarding this problem.

B31.3 does not issue industry alerts. The options open to B31.3 are either a Code revision or a Code Case. These options were evaluated by the Materials subgroup (assisted by the Edit subgroup).

Because of the magnitude of the implied Code change (additional impact testing requirements for common materials), the materials subgroup had insufficient justification to support a Code change. (Note that because of processing time required for a Code change, this change would have a very low chance of making the 2016 edition of B31.3.)

A Code Case would better serve as a sort of “industry alert”. A Code Case is essentially an internal Request for Interpretation. Any person can request a formal interpretation of the Code, and formal interpretations are approved and published by the Committee at each (bi-annual) B31.3 meeting.

A Code Case is a request made by the Committee itself. In such a manner, the Committee can quickly publish “guidance” to address issues rather than waiting on the full balloting and publishing schedule of next Code edition. No such Code Case has been balloted by B31.3 to date.

One outcome of the B31.3 presentation is that a member of the Board on Pressure Technology Codes & Standards (BPTCS) agreed to add this topic to the summer Board meeting. Here again, no industry alert is forthcoming.

There is action in Section VIII. An active proposal there will further qualify “as forged” A105 flanges for cold service.

Additionally, construction code committees are aware of this issue and spreading the word. The Mechanical Contractors Association of America published the National Certified Pipe Welding Bureau (NCPWB) Technical Bulletin, Risk of Brittle Fracture of Carbon Steel Piping During Hydrostatic Testing.

Heurtey Petrochem Enhances Engineering, Design and Analysis Accuracy with Intergraph® CADWorx® Analysis Solutions

Read how a leading international engineering group engineers and designs process heaters for a gas to gasoline plant in Akhat Velayat, Turkmenistan.

Process heaters for gas to gasoline plant
Heurtey Petrochem was contracted to do the engineering, fabrication, inspection, testing, packaging and shipment of seven process heaters for a new gas to gasoline plant in Akhat Velayat, Turkmenistan.
The main goal of the project was to efficiently create up-to-date and factual P&IDs, design the heater coils and the external piping located on the heater as well as the design of piping skids.

Heater cabin, designed with Intergraph CADWorx Plant Professional.

Finding a solution provider
As a long-term AutoCAD®-user, Heurtey Petrochem was looking for a solution that would run in an AutoCAD environment, have flexible licensing possibilities suitable for different project types, and have affordable pricing options. The company was also already familiar with the high quality of the Intergraph® solutions, and recognized the value of having one solution provider for different engineering departments.

Intergraph solutions were used throughout the project by the Heurtey Petrochem’s piping department. From creating P&IDs, 3D modeling, stress analysis, coils and piping layouts to producing isometrics and extracting materials information, Intergraph CADWorx® & Analysis Solutions helped Heurtey Petrochem to improve efficiency and accuracy of engineering design and analysis work processes and deliverables.

An example of how the piping will be located on the actual heater. Created in Intergraph CADWorx Plant Professional.

Realizing results
In addition to creating P&IDs, the overall project scheme included 3D modeling, stress analysis and fabrication for the heater coils. Isometric diagrams, support modeling, and material procurement was also executed with Intergraph solutions. Besides this, also the external piping for the heater and the skids were designed, analyzed, and procured using Intergraph solutions. Tie-in, line and valves list was obtained from Intergraph CADWorx P&ID, while CADWorx Plant Professional was used for 3D modelling, and CAESAR II® for stress and support structure analysis.

During the project, eight project team members worked in CADWorx Plant Professional, whilst CADWorx P&ID and CAESAR II were used by one engineer each. The new system manages .DWG and .C2 files for tens of megabytes of data as well as tens of thousands of records in .mdb file format.

By using Intergraph CADWorx & Analysis, Heurtey Petrochem was able to secure the following benefits:

  • 50% cost savings (traditional 2D vs. 3D) for medium-sized projects.
  • Increased quality of work processes and documentation.
  • Improved efficiency by decreasing the time spent on non-engineering activities.
  • Ability to better track deadlines and budgets throughout the project.

Moving forward
Currently, Heurtey Petrochem is using Intergraph solutions in three different engineering projects, and considers expanding the use of the solutions in the future. Remus Marinescu, lead piping engineer at Heurtey Petrochem Romania commented on their use of Intergraph solutions: “The slogan Shaping Smart Change perfectly describes the way the company helps to drive improvements in efficiency and engineering quality by providing smarter engineering solutions.
