Understanding SIFs, Stiffness, and Allowable Loads

Piping and pressure vessel engineers face a complex challenge when designing safe, reliable systems: accurately evaluating stresses, deformations, and fatigue risks in intricate components like nozzles, elbows, saddles, and pipe shoes. Finite...

Advanced Modeling for Complex Piping Systems

Modern process facilities often face design challenges that extend beyond the limits of conventional piping codes. Systems with large...

Design By Analysis: Stress-Based Approaches to Evaluating External Loads in Nozzles

The evaluation of flange designs has evolved with the incorporation of Code Case 2901 (CC 2901) into ASME Section VIII, Division 1 (UG-44(b)) and...

Understanding Cyclic Behavior and Ratcheting Analysis: Advancements

Ratcheting is a critical failure mode in pressure vessels and piping systems, occurring when progressive and incremental plastic strain accumulates...

Finite Element Analysis in PVP Design: What You Should Know

In pressure vessel and piping (PVP) design, various analysis methods are used to assess the safety and performance of systems. While hand...

Redefining Modern Pipe Design With Finite Element Analysis

As piping systems advance, engineering methods must adapt to meet the changing demands. This was the key realization for Robert Weyer, Lead Piping...

Modern API 579, Fitness-For-Service Solutions

What was earlier a rudimentary approach, characterized by a "build it and run it" perspective for ensuring the structural integrity of an asset, has...

When Sloshing in a Vessel Matters

It is our everyday knowledge that special care is needed to move any small container partially filled with liquid.

Pipe Stress: 5 Things Managers Should Know

Piping systems are the unsung heroes of industrial infrastructure, carrying fluids to the necessary places. But behind their seemingly simple...

ASME B31.3 Updates to Stress Range Factors & The Impact on Pipe Design

In the latest edition of the ASME B31.3 code (2022 edition), there have been significant changes to the allowable stresses for expansion load cases...
