PDMS Piping Design – PDMS pipework Tutorial – Aveva PDMS 12 Training Videos
Pipe routing is probably the activity that consumes most time on any large project and it is also one, which causes the
most problems. Pipe routing in PDMS has always been one of the major strengths of the system, as you will discover in
The following Training Manual includes all the fundamentals of Equipment building including positioning and orientation
both by attribute manipulation manually, but also using graphical picking which also introduces event driven graphics.
At the end of this training, you will:
• Know how to create equipment elements.
• Know how to create, position, orientate and connect primitives.
• Know how to modify elements and manipulate attributes.
• Understand the principles of graphical hits to modify elements
• Manipulate the graphical representation of elements.
All branches need to have a start and end point. These can be a position in space (3D co-ordinates), the flange face of a nozzle, a tee or various other points in your design. Heads and tails are set up via a series of attributes that belong to the branch element.
(pdms training): The next step in designing a pipe is to create and position a series of fittings, which define the pipe route you require.
Just as on a drawing board, you need to decide which piping components are needed in order to satisfy the
requirements of the process. The components must be arranged so that the pipe meets its design needs. However,
unlike on the drawing board, you do not need to know any fitting dimensions, PDMS derives these automatically from
To create piping fittings, you need to select an item from the list of fittings available to you from the associated piping
specification. Typical types of fitting available are Elbows, Tees, Reducers, Flanges, Gaskets and Valves etc. There is
some intelligence build into the PDMS forms so that by placing for example a valve the associated Gaskets and Flanges
will also be created.
For all piping components, you will need to carry out the following steps: -
Select the component from the piping specification, position the component and set the orientation.
There tube is not created explicitly it is created automatically or implied by placing fittings.
In the same way that design offices have standard piping specifications, PDMS has a set of specifications from which
you can choose. In fact all the components you will use in PDMS must be defined in the Catalogue and be placed in a
Specification before you can use them. In the Training Project there are three such specifications:
A1A-TRA = ANSI CLASS 150 CARBON STEEL
A3B-TRA = ANSI CLASS 300 CARBON STEEL
F1C-TRA = ANSI CLASS 150 STAINLESS STEEL
These specifications contain all the fittings you will require for the course exercises.
