Pipe Stress Analysis Services across Canada and USA by Experienced Professional Engineers

At Little P.Eng., one service has been foremost throughout that time namely, Pipe Stress Analysis. Hundreds of Pipe Lines have been formally analyzed by us using dedicated Pipe Stress Analysis Software and in accordance with International Piping Design Codes. Solutions have been found, by means of numerous Iterative Analysis Trials, for each Pipe Line and Pipe System to ensure Safe Design and full Compliance with the ‘Pressure Systems Regulations’. Typical stages of this Service are set out below for information purposes.


At Little P.Eng., Pipe stress analysis is an analytical method to determine how a Plant or Piping system behaves based on its material, pressure, temperature, fluid, and support either above ground or underground.

This analysis calculates piping stresses resulting from thermal cycles, pipe and fitting weights and static pressure for the main process piping. Generally, we evaluates stress due to thermal cycles, weight, and static pressures in the piping as per all industry piping codes, such as B31.3, B31.8, CSA Z662, BS826, BS7159, FDBR, DNV and others.

We calculate loads on equipment (e.g., piping’s, vessels, coolers, pumps, and compressors) and make recommendations to meet up with industry standards.

  • Simulate Operational Plant and Piping Vibration Pattern and deflections

  • Recommends pipe layout, pipe support, and clamp designs and lots more.

A Typical ‘Scope of Work’ for a Little P.Eng. Pipe Stress Analysis Project:

  • Stage 1: The Stage 1 Analysis covers the Initial Modelling and Preliminary Pipe Stress Analysis of the Pipework included in the Project. Provisional feedback is provided to the Client.

  • Stage 2: The Stage 2 Analysis covers the Final Modelling and the Pipe Stress Analysis of the pipework under consideration with the inclusion of the agreed adjustments (if practical) found from the Stage 1 and 2 Analyses. Preliminary copies of the Marked-Up Model Plots are issued to the Client and these specify the Support and Pipe Configuration ‘Solution’ for the Pipework. Preliminary Support and Equipment Loadings are also issued at this point. This Stage includes the Post Processing of the Results and the writing of formal Analysis Reports. Once completed the Reports are formally issued to the Client together with additional sets of the Marked-Up Plots.

  • Stage 3: The Stage 3 work covers further liaison with the Client to confirm and check the interpretation of the provided Specifications for the ‘Solution’ in terms of Supports and Pipework Configurations. For example, this would include Little P.Eng. reviewing the Support Detail and associated Steelwork Drawings together with the Pipework Isometrics. It may also include, if required, Site Visits for Little P.Eng. to Review the Installation.

Vibration-induced fatigue, pipe stress, transient events and small-bore connections are high-risk areas requiring Little P.Eng. engineering support.

At Little P.Eng., we help you paddle towards prevention rather than reaction.
