Natural frequency is determined by the physical properties of a piping system, like mass and stiffness, without any external driving force. This natural frequency in a piping system is affected by...
Piping Stress Basics
Dynamic Pipe Stress Analysis is a specialized engineering evaluation used to assess how piping systems respond to time-dependent (dynamic) loads, such as: Seismic activity (earthquakes) Water...
In the piping engineering industry, the terms FIV, AIV, and Random-Vibrations refer to different types of vibration phenomena that can affect the integrity and safety of piping systems. In recent...
The Y factor is a dimensionless coefficient used for calculating the required wall thickness (t) for thin-walled pipes under internal pressure. According to Equation 3a of ASME B31.3, for determining...
GRE Design Envelope (Failure envelope) is a 2-dimensional (2D) graphical plot of hoop stress and axial stress that provides safe operating conditions of GRE piping/pipeline system when subjected to...
Creep Fundamentals and How ASME BPVC Address This Phenomenon
This not-so-brief write-up is basically a summary of my notes on this subject when several years back I decided to study this interesting subject in somewhat detail. For interested readers, this is...
