The last few years have seen a dramatic increase in the use of personal computers for piping engineering. Low-cost, personal computer-based plant design packages provide the major capabilities of mainframe-based systems and offer them at a far lower price.

The personal computer-based plant design market has long been dominated by AutoCAD software. More recently, third-party vendors have developed add-on packages to AutoCAD that provide needed plant design capabilities such as bill of materials creation, automatic generation of isometrics, interference checking, etc.

There are many advantages to design software built around the AutoCAD graphics engine. The AutoCAD user interface is widely known, thus minimizing training costs and startup time. The developer does not have to duplicate CAD software functionality, thus reducing program purchase costs. AutoCAD is also available on a wide variety of hardware platforms which the add-on products are usually able to support.

The Advent of Personal Computer-Based Piping Design Plant Engineering Magazine (Article from 1995)

Valves in petrochemical and refining installations are subject to numerous standards and specifications issued by many supporting organizations. Today's valve standards are dynamic documents that reflect sound engineering practice, changes in market demands and changes in technology and manufacturing procedures.

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.
