Piping Isometrics
Introduction: The word ‘Isometric’ has its origins in Greek which is the case with many English words. It is derived from Greek word ‘Isometros’, of equal measure (the objects measured using a fixed unit). It is one of the most important outputs, if not the most important output of overall Piping effort. Isometric is a…

Piping Guidelines for P&ID Review
A P&ID is a schematic drawing of a process plant system. It has no relationship to scale, relative dimensions or true shape or character. It has no relationship to north, south, east or west. It has only a marginal relationship to up and down. However, through the use of standard symbols, line conventions and notes…

Checking Drawings
Piping Designers – Check yourselves For those independent designers that work on their own, or that preliminary work that goes out for bid, there is no substitution for perfect work.Incomplete work and errors, all cost extra. Here are some useful tips to reduce what a checker would find to almost nothing. As a first step, check…

Checking, Quality Assurance and Quality Control of Piping Drawings
Checking or the Quality Assurance & Quality Control (QA/QC) in process plant piping engineering and design is a grossly misunderstood activity that is performed (or should be performed) by every piping group on every process plant project deliverable. Problems arise when checking is not done and when it is done it is often done incorrectly….

Introduction to Line Numbering
This article is intended to answer some of the questions that come up about the subject of Line Numbers and Line Lists for a typical process plant project. Some of the questions that come up about Line Numbering include: What is it? Why is it? What does it mean? Who does it? Another question is…

Checking of Pipe Fabrication Shop Drawings
There will come a time the life of almost every project when the question of checking of pipe fabrication shop spool drawings will come up. Any time drawings are created there will be the potential for errors.The shop is responsible for checking their own work, but it is prudent for the engineering company to…

Underground Piping Plans
One of easiest piping plans to be generated, but also one of the trickiest! Basically you are documenting ALL piping that is to be buried in a given area. This “area” is normally the whole facility!
