This article summarizes a recent finite element analysis (FEA)-based study that employs creep simulation techniques to investigate the elevated temperature response of piping with peaked longitudinal weld seams.
This bulletin is part of a series of WRC Bulletins that contain the technical background and other information to evaluate damage mechanisms in various industries to facilitate the use of API 579. These bulletins, shown below, will be updated based on the latest knowledge and technology developed for identification of damage mechanisms.
The following is the final part of a 2-part series outlining the relationship between key operating parameters and corrosion that has been used to develop a set of guidelines to define an operating envelope.
Corrosion and fouling in HF Alkylation Units are closely linked to feed quality and operating conditions. This article outlines the relationship between key operating parameters and corrosion that has been used to develop a set of guidelines to...
