This course now covers the complete ASME B31.3 Process Piping code and ASME B31 piping engineering fundamentals — from design basis through materials, pressure design calculations, flexibility analysis, fabrication, examination, pressure testing, and API 570 and PE exam preparation.
Over 300 practice questions across both course components.
If you design, review, inspect, or procure process piping — or you are preparing for the API 570 or PE exam — this is the most comprehensive ASME B31 piping course on Udemy.
The course is structured in two parts.
Part 1 — ASME B31.3 Process Piping: Code, Design and Exam Prep is a dedicated deep dive into the B31.3 code as it applies in chemical, petrochemical, oil and gas, pharmaceutical, and general process industry plants. This section covers the B31.3 framework and fluid categories, materials and allowable stress determination, the Clause 304.1.2 wall thickness equation with worked examples, pressure-temperature ratings for flanges and fittings, branch reinforcement using the area replacement method, the displacement stress range equation and SIF values, examination requirements by fluid category, pressure testing, pipe supports and layout, and dedicated exam preparation for API 570 and PE candidates. An expansion module covers corrosion mechanisms, remaining life calculation, and an introduction to API 579 fitness-for-service assessment.
Part 2 — ASME B31 Piping Engineering Fundamentals covers the core piping engineering principles used across all B31 codes: pipe sizing, material selection, internal and external pressure design, buried piping, stress and flexibility analysis, support design, and valves. This section builds a solid foundation across the B31 family for engineers new to piping or consolidating their fundamentals.
Every calculation section includes worked examples. Downloadable resources include a Wall Thickness and Branch Reinforcement Calculator in Excel, a Pipe Schedule and P-T Rating Quick Reference, a B31.3 Clause Navigation Card for open-book exams, a Flexibility Quick Reference Card, and a three-scenario Exam Practice Pack with model answers.
