After a busy year of travelling and teaching courses in Holland, Kuwait and South Africa I have finally got down to writing.

This months’ tip rant.

3D CAD programs for plant design.
Ever since CAD programs appeared in the early 1980’s, management of engineering companies have been saying that 3D CAD will mean the demise of expensive piping designers as the programs will solve any and all of the piping layout and detail problems and route piping in a manner which is both efficient and cost effective.

Things are on the up and up. Summer is here and the birds are chirping and things are a lot better on the job front.

This months’ tip

The selection and sizing of spring hangers can be accomplished using whatever piping stress analysis software program. However, the selection should ALWAYS be checked using the manufacturers’ catalogue. The reason for this is that the stress program does not know what purpose the spring is being used for. For instance if you are trying to limit the loads on pump nozzles to a certain value and have located a spring on the piping close to the nozzle, the selected spring has been chosen by the program after completing a piping system moment calculation and distributing the loads amongst the restraints in order to achieve equilibrium.

Well guys spring is here and good times for pipers are back again. Activity in both the process and power industries have spawned a shortage in Piping Designers and Engineers. As we all know this business is very cyclic and when things get moving after a slump, like we’ve had in the last few years, there is always a shortage of experienced people.
The trouble is that a lack of worthwhile practical training is and always has been difficult to find. Colleges and Universities may offer some pseudo piping courses but they are usually so far removed from the real world that they are largely ineffective in the short span. Learning institutes are profit centres and wish to fill every class with paying students and most young people from North America are not interested in pursuing careers in Engineering.
