Intersting AST Analysis

Friday, February 17, 2017   By: JGardiner [1848] 0 Stars
Greetings all,

New to the forum but have been working with API-650 tanks, mostly in the commercial nuclear industry. Wanted to share an interesting project!

In the nuclear industry ASTs are used to store water essential for the cooling of the reactor. We used finite element analysis to evaluate the tank subjected to winds of 360 mph and struck by a tornado missile. In this case an airborne pickup truck going 80 miles per hour. Its amazing how a thin metal tank and its energy-absorbing contents can withstand the impact and maintain its integrity..Definitely not an API-650 code case!

Look forward to great discussions on this forum!

Jeff!

AST or Aboveground Storage Tanks are built or designed on the basis of the thin membrane stress theory as opposed to a ASME B&PV Code which is not. API650 tanks are very flexible under extreme conditions and behave like a bladder. Dont know about the flying pickup truck or 380 mph winds.

Industrial Training School

 

Instrumentation - I

An Instrumentation Training Course that provides an overview of insturmentation architecture with instruction on primary elements and how they interface with controllers and final elements.  Instrumentation-1 can be considered an introductory course on instrumentation.

Basic Instrumentation training course addresses basic instrumentation topics with quizzes for comprehension of the covered lessons presented in the Basic Instrumentation textbook.  As a Basic Instrumentation by distant learning it is in a correspondence course by mail format.  This basic instrumentation correspondence course consists of 6-Lessons on basic instrumentation and does not require internet access or a computer.

Testimonies:


John P. said "...I recommended this [course] to someone already...!"

Dmytry B. said "As an electrical-electronics background person, I am extremely satisfied with the obtained knowledge."

Alonzo F.  said "It greatly enhanced my understanding of process control and measurements...benefited from the feedback from my instructor. Thank you."

 

Instrumentation - II

A comprehension instrumentation training course that provides indepth: controller usage, wireless security, primary and final element usage for processes, and instrumentation problem solving problems.
