Valves Standards - Refining and Petrochem

<<This document focuses on some of the important standards that affect
steel, gate, globe and check valves in refineries and petrochemical installations. Some mention will also be made of other valve specifications, however specifications for control and relief valves will not be covered. Early in this century, when our nation's petrochemical and refining industries were in their infancy, pipe, valve and fitting (PVF) manufacturers as well as end-users had no standards to go by. The design and function of their products were dictated and affected by actual feedback from the end user - be it years of effective service life, catastrophic failure or incompatibility with similar products from other manufacturers. This lack of valve, flange & fitting interchangeability with other manufacturers products, resulted in two primary groups addressing the standardization issue.>>

And if you don't know all the answers, you have to get some help. But whom do you ask? Where do you look? If you had a tough valve application questions 10-20 years ago, there was probably someone in your organization that held the unofficial title of 'valve guru', and he would have the answers based on his years of experience and focused interest.

Valve Repair in the 21st Century United Valve

<<Once upon a time, most large refineries and chemical plants had their
own valve shops, complete with a full compliment of experienced valve repair technicians. These service departments took care of most of the plants repair needs, although oftentimes valves were simply replaced rather than refurbished.>> Received on Wed Feb 25 18:31:00 2004
