- Automation
Strategy
- There are three primary strategies associated with Plant Design
automation. The first is the transition away from paper deliverables towards
data deliverables. The second is viewing project-generated data throughout
an office or company, thus providing an enterprise-wide view of that data.
The third strategy is compressing schedules, with an emphasis on why
concurrent engineering is here to stay. This article discusses the pros and
cons of those strategies.

Design Tips
- These pages list design tips and tricks on piping and equipment layout,
stress analysis, material takeoff, and project management. What makes these
pages exciting is that you can submit tips yourself and have them show up on
the site. Another useful feature is that you can 'rate' the tips! Those tips
that are rated the most useful 'float' to the top of the list. Become the
acknowledged Plant Design expert as rated by your peers! Submit your Design

- Double Overhang
- A common type of pipe routing that impacts the allowable spans of piping
runs is the 'unsupported overhang'. The allowable span for this type of
arrangement is what this article is focused on. This is the type of routing
a Designer sees at turning points of piperacks. The supported piping has one
length of pipe hanging over the last support beam in the rack. The pipe then
turns up or down and then travels at a right angle to the next support,
usually with a different length of pipe. This article discusses how to
calculate the allowable span between pipe supports for this type of piping
arrangement.

Equipment
Spacing
- This article is an introductory explanation of
spacing equipment in a plant to satisfy the safety and maintenance
requirements of a plant.
-
- Flange Data
- Dimensional data on flanges.
-
- Plot Plans
- In addition to depicting relative and specific positioning of equipment,
plot plans help in the establishment of support facilities and are used to
determine the most cost-effective construction sequence and methods. Plot
plans are also used to assure proper operator and maintenance access while
maintaining engineering economy. Plot plans are used for operational needs
such as training and emergency access, as well as facilitating insurance
ratings. In this page, the development of plot plans is discussed.
-
- Project Management
- This
site will take you through the basics of project management. The three
main topics covered are Organizational Structures (pure versus functional
management organizations - the pros and cons of each type); PM Challenges
(looking at the primary problems on a project through the eyes of its
project manager); and, Cautions (when project management tools may cause
more harm than good). Why is project management important to almost all
firms? For the answer to the question, click on the thumbnail image to the
left of this paragraph. The thumbnail image will expand to a readable size.

References
- This Reference link will take you to a group of pages that catalog links
to sites or web pages that members of the Society of Piping Engineers and
Designers may find useful.
-
- Rise/Run Tables
- An Excel spreadsheet that gives you the various rise/run dimensions for
offset pipe.
-
- Variable Springs
- This article from Piping Technology Products describes how to design and
build spring cans. There are specifics on the physics of spring cans, how to
size variable springs, and how to calculate variability. Good reading for
anyone responsible for the design of pipe supports or the layout of hot
piping systems.
