Here is something else that may be helpful to your career goal. By: James O. This includes; the thermal forces and the live and dead loads the piping system imposes on equipment, equipment nozzles and structures. The Pipe Stress Engineer is also responsible for the selecting and specifying stress related products including various types of Expansion Joints, Constant Support Spring Hangers and Snubbers or Struts.

What does the Pipe Stress Engineer need to know? Pipe Stress Engineering is more than just knowing how to turn on the Analysis software in the computer, how to find the menus and the difference between pass and fail. So, appropriately, what else does the Pipe Stress Engineer need to know about piping? Here is a list of the most basic of things that a good Pipe Stress Engineer should know. Thinking about every one of these items should become as natural as breathing for a good Pipe Stress Engineer.

This includes the many types of fittings, the many different schedules, the wide variety of common piping materials, the flange class ratings and the types of the different valve designs.

They also need to know and understand the pipe stress related issues that effect each type of equipment. This includes pumps, compressors, exchangers, filters or any special equipment to be used on a specific project. When a new project introduces a new material with severely reduced span capabilities; supplemental training may be required. It has a temperature and that temperature causes it to grow and move. That growth and movement must be allowed for and incorporated in the overall design.

Not just of that specific line but for all other lines close by. The process of expansion in a pipe or group of pipes will also exert frictional forces or anchor forces on the pipe supports they come in contact with.

Routing for flexibility can normally be achieved through the most natural routing of the pipeline from its origin to its terminus. Routing for flexibility means a do not run a pipe in a straight line from origin to terminus and b building flexibility into the pipe routing is far cheaper and more reliable than expansion joints. They need to know and understand that everything has a weight.

They need to be able recognize when there is going to be a concentrated load. They need to have access to basic weight tables for all the standard pipe schedules, pipe fittings, flanges, valves for steel pipe. They also need to have the weight tables for other materials or a table of correction factors for these other materials vs. They need to be able to recognize when downward expansion in a piping system is present and is adding live loads to a support or equipment nozzle.

They need to know that nozzle loading is important and does have limitations. It does not matter how wide or how high the rack or what kind of plant, the logic still applies. Starting from one or both outside edges the largest and hottest lines are sequenced in such a manner that allows for the nesting of any required expansion loops.

Another good guideline is; Process lines on the lower deck s and Utility Lines on the upper deck s. The spacing of the lines must also allow for the bowing effect at the loops caused by the expansion. One rule of thumb for setting the distance between piping levels is three times the largest pipe size.

This should include the most common sizes, schedules and materials. They also need to be able to calculate forces of individual line anchors and the combined forces of all lines at a specific support. They need to understand what each one is along with when to and when not to use each. Every Pipe Stress Engineer must also be able to go to the field or sit in front of a client and make proper, intelligent, and understandable pipe stress decisions.

They must also be able to produce detailed final analysis packages. Today, Pipe Stress Engineers also need to know or be able to learn a wide range of electronic 2D or 3D design tools. Stress Sketches become a part of the Legal Records for the Project.

Therefore all notes and comments on Stress Sketches must be well thought out and clearly written in order to clearly communicate the required and agreed to changes to the design. Adding Expansion Joints at the expense of increased maintenance may not be the most cost effective solution to a perceived stress problem. Any person that has this type of training, this type of knowledge and then consistently applies it is indeed a Pipe Stress Engineer.

He or she will also be a more valuable asset to their company and to themselves in the market place. On the other hand anyone who does not know or does not apply the knowledge about these issues while doing piping work not making a proper cost effective contribution to the Project, the Company or to their own career.

One of the most important things that must be understood about the ASME B31 Pressure Piping Codes is that the structural analysis methodologies presented there are based upon beam theory albeit they do not preclude other valid methodologies and the software for piping structural analyses are based upon beam theory. Review the loadings on the system weight dead weight and live weight , wind, thermal expansion thrusts, seismic excitation, etc. You must focus upon following the load path all the way to the ground the point where the Civil Engineer takes over responsibility.
