Pipestress 3: Calculations of Pressure Retaining Components

When piping systems are exposed to internal pressure, specific stresses and forces arise in components such as bends, flanges and branch connections. Pipe Stress 3: Calculations for Pressure-Retaining Components focuses on analysing and assessing these situations. In this training course, you will gain a deeper understanding of how pressure loads affect individual components and how to account for these effects in technical assessments within piping and engineering projects.

Course programme

Pipe Stress 3: Calculations of Pressure-Bearing Components according to Different Standard Codes is the third part of the Pipe Stress training programme. While Pipe Stress 1 and 2 focus on piping systems, expansion, flexibility, supports and forces in piping, Pipe Stress 3 goes deeper into the calculation and assessment of pressure-bearing components.

Across six teaching evenings, participants cover the assessment of structures, stress categories, allowable stresses, pressure testing, design formulas for cylinders, spheres, cones and toruses, dished heads, nozzles, flat plates, stability, flanges, columns, horizontal vessels on saddles and local loads.

The focus is on technical understanding, code interpretation and calculation-based assessment. Participants learn how pressure-bearing components are assessed according to different standard codes and how design choices influence strength, stability, safety and reliability of pressure equipment.

PED and WBDA Training for Pressure Equipment and Piping

Technical Modules 2 half-day sessions Rotterdam

This PED and WBDA training course focuses on the application of the Pressure Equipment Directive, PED 2014/68/EU, and the Dutch Commodities Act Decree on Pressure Equipment within industrial projects. In practice, PED is rarely about theory alone. It is about correctly defining scope and obligations. Especially in brownfield modifications, replacements and extensions, the distinction between mandatory and optional requirements is often unclear.

This regularly leads to unnecessary calculations, overly heavy conformity assessment module choices and more involvement from a Notified Body than necessary. In this training course, you learn how to classify pressure equipment correctly, determine the correct PED category and conformity assessment module, and identify when inspections such as KVI are actually required. The emphasis is on making the right technical decisions under PED and WBDA in Dutch practice, from new-build projects to modifications and the management of existing installations.
