What is ASME B31.3?
The global standard for process piping design
ASME B31.3 is the international standard for the design, fabrication, assembly, inspection, and testing of process piping. Published by the American Society of Mechanical Engineers, it is the governing code for piping in refineries, chemical plants, pharmaceutical facilities, LNG terminals, and cryogenic plants — making it the most widely applied piping code in the world.
A working command of B31.3 is table-stakes for piping, mechanical, and stress engineers on every major EPC project. The code defines allowable stresses, service categories (Normal, Category D, Category M, high-pressure), thickness calculations, flexibility analysis, fabrication and welding requirements, and inspection and testing rules. Every clause has implications for safety, cost, and schedule.
Pair B31.3 fluency with CAESAR II modeling skill, and you hold the combination that every EPC stress group and piping team actively recruits for across India, the Gulf, Europe, North America, and South-East Asia.
What You Will Learn
Six pillars of ASME B31.3 competence
From first principles to CAESAR II stress reports — every skill a process piping engineer needs.
Material Selection
ASTM pipe and fitting specifications, material compatibility with process fluids, low-temperature toughness, and PMI requirements.
CAESAR II Modeling
Hands-on: geometry input, load cases, support selection, stress interrogation, nozzle loads, and code-compliance reporting.
Stress Analysis
Sustained, expansion, and occasional load cases; SIFs and flexibility factors; WRC 107/297 and API 610/617 nozzle checks.
Fabrication & Welding
WPS/PQR review, PWHT, hardness testing, weld examination categories, and severe-cyclic service considerations.
Testing & Inspection
Hydrotest, pneumatic test, leak test; inspection examination categories; weld NDE sampling per fluid service category.
Curriculum
12 modules — foundations to advanced service
Work through the track linearly or jump into any topic. Every module awards its own CPD-accredited certificate.
Code Structure & Scope
Chapter layout, fluid service categories, relation to B31.1 and other ASME B31 codes.
Design Conditions & Allowable Stresses
Design pressure, design temperature, Table A-1 allowable stress, and material quality factors.
Pressure Design of Components
Straight pipe, elbows, branches, flanges, blanks, reducers — thickness and reinforcement calculations.
Flexibility & Stress Analysis
Sustained, expansion, and occasional loads; SIFs; flexibility factors; code equations 1a, 1b, 1c.
CAESAR II — Setup & Modeling
Geometry nodes, materials, insulation, diameters, boundary conditions, and first analysis run.
CAESAR II — Supports & Iteration
Rigid supports, spring hangers, guides, stops, snubbers; iterating to resolve failed stress nodes.
Nozzle Loads & Equipment
API 610 pumps, API 617 compressors, API 660 exchangers; WRC 107/297 vessel nozzle checks.
Materials & ASTM Specifications
Carbon steel, low-temperature, stainless, duplex, nickel alloys; ASTM A106, A312, A335, A333, etc.
Fabrication, Welding & WPS
Joint types, welding processes, WPS/PQR review, PWHT, and impact testing.
Inspection, Examination & Testing
Examination categories, NDE sampling percentages, leak testing, and code stamping.
Dynamic Loads & Occasional Cases
Wind, seismic, PSV reaction, slug flow, water hammer; harmonic and time-history overview.
Special Topics — Cat M, High-Pressure, Duplex
Chapter VIII (high-pressure), Category M (severe service), and duplex stainless considerations.
