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…
A dead-leg in a purified water system can contaminate the entire distribution network resulting in lost production, contaminated product and down time for cleaning. Pharmaceutical pipe dead-legs: what’s that all about? Purified water (drinking water treated using million pound purification plants) is frequently used in the pharmaceutical industry during the manufacture of tablets and medicines. This…
Stress related technical and execution problems in the design of process plant piping are complex and must be addressed properly. There will be some Piping Designers, Stress Engineers and others who read this and say that they agree.Others may say that they do not agree. Others will just not know one way or the other. This…
Article courtesy of Piping Technology & Products, www.pipingtech.com Introduction: PT&P produces various kinds of snubbers. Why snubbers are used and how they function are briefly discussed here. What are they? Snubbers are restraining devices used to control the movement of pipe and equipment during abnormal dynamic conditions such as earthquakes, traveling shock waves caused by…
The subject, “Pipe Supports” is a much more complex subject than the term suggests.Let’s talk about Primary & Secondary pipe support systems.Pipe supports is a general term that actually is split into two families. There is what I call the primary pipe support systems, and then there are the secondary pipe support systems.The primary pipe…
Vessel orientation is normally the only equipment related layout activity that can be done without specific input from a vendor. All of the information required for vessel orientation is generated on the project in the form of P&ID data and project standards. It is also one of the few activities that will feed one or…
The question on many minds may be “Why does Piping do Vessel Orientation?” We can answer that question two ways. The first answer would be, because of the traditional role of Piper and the content of the vessel orientation activity itself. The traditional role of the Piper has always been the bringing together of multi-discipline…
This article should only be used as a guide. It’s intended purpose is to help the piping designer who is responsible for placement of one specific item in a typical refinery, chemical or petrochemical process plant or someone who may need help in developing a total plot plan for a complex unit. The guidelines given…
A flange is defined as a plate type device, normally round, that is attached to the end of a pipe, fitting, valve or other object to facilitate the assembly and disassembly of a piping system. Flanges, Gaskets & Bolts (Just the basics) Revision 1 Note: This article covers ASME B 16.5 Standard Piping Flanges up to…
