Piping Design: An Introduction For Non Piping Engineers
This paper attempts to explain some of the salient piping activities (along with their sequence) and interaction with other disciplines during detail engineering. Piping Engineers and Designers may find some of it too rudimentary. This is deliberate. The constraints have not been touched upon. Moreover, any single write-up based on a typical job cannot do justice to vast number of activities that a piping team performs.
This is arguably the most challenging single activity because almost all input except Process P&IDs and Engineering Design Basis is fluid. The challenge involves creativity, ability to draw upon experience of similar jobs, provisioning for unexpected changes and resolving often conflicting requirements.
The equipment layout thus prepared is sent to almost all major disciplines and Client for their comments. These comments are then consolidated and the conflicting ones are discussed across the table. The layout is now ready for dissection by core group of senior piping people, and this experience of being grilled and cross-examined is a ritual that signifies coming of age of a piping engineer. Changes which affect others are once again taken up with respective disciplines. This layout is then put up for Apex Review.
The adage that piping study is 'half science and half art' is true. The art part is visualization and creativity while science refers to following the established norms; however, what is forgotten is that a piping study involves lot of dedication, risk-taking ability and discipline. A piping designer is at work 24 hours. A good scheme, solution or an alternate striking at midnight is not uncommon, something akin to Archemides and Eureka! Many a times the designer would also have to release fronts for downstream users even when the input is still coming and then he must constantly be on the vigil for changes in input. A good designer knows not only how he is affected by others but also how his work affects others.
