Online Course for Piping Engineers
Pipe Stress Analysis according to ASME B31.3 and EN 13480
-
Learn to calculate pipe stresses by hand, verify software results, and build engineering judgment using ASME B31.3 and EN 13480 code equations through worked examples and real system analysis.
- For piping engineers, mechanical engineers, and pipe designers working on process piping projects.
Lesson Previews
Why Take This Course?
-
Master Code-Compliant Analysis
Apply ASME B31.3 and EN 13480 stress equations to calculate wall thickness, sustained loads, occasional loads, thermal expansion, and fatigue—and understand why the codes require each calculation.
-
Build Engineering Judgment
Perform pipe stress calculations by hand using fundamental physics, enabling you to verify software results, identify errors, and solve problems when analyses don't behave as expected.
-
Prevent Real Failures
Learn failure mechanisms in bends, reducers, tees, flanges, and nozzles through real system examples, and apply Stress Intensification Factors (SIFs) to assess critical components correctly.
What Will You Learn?
-
- Calculate hoop, axial, and radial stresses in pressurized pipes and determine minimum wall thickness according to ASME B31.3 and EN 13480 using pressure, diameter, and allowable stress values
-
- Perform complete pipe stress analysis by hand including sustained loads, occasional loads, thermal expansion, and fatigue using code stress equations and allowable value tables
-
- Apply Stress Intensification Factors (SIFs) to evaluate bends, reducers, and branch connections where standard stress calculations underestimate actual stress concentrations
-
- Evaluate nozzle and flange adequacy under combined pressure, weight, and thermal loads using WRC 107/297 methods and code-compliant flange analysis procedures
-
- Design support systems with correct spring supports, steel structures, gaps, and friction considerations that balance operational requirements with thermal expansion flexibility
-
- Identify overstressed locations from analysis results and implement solution strategies, including expansion loops, bellows, support modifications, or design changes
-
- Distinguish between load cases (sustained, occasional, operating, expansion, fatigue) and apply appropriate code allowables for each failure mechanism
-
- Interpret pipe stress software analysis results and verify that calculations match hand calculation methods for fundamental understanding
-
