Finite Element Analysis, or FEA, allows engineers to model and analyze complex systems that would be impossible or impractical to solve by hand calculations alone. With FEA, engineers can break down a complex system or structure into smaller, simpler parts or elements, and then use numerical methods to solve for the behavior of each element. These element solutions are then combined to give an overall solution for the entire system. While the origins of FEA can be traced back to the work of engineers and mathematicians in the 1940s and 1950s, the modern development and widespread use began in ..read more

Darryl Stoyko and Golden Boy The Golden Boy is a statue on the Manitoba Legislative Building in Winnipeg, Manitoba. Arguably the province’s best-known symbol, it was modeled after the Roman god Mercury and is meant to represent the prosperity and entrepreneurial spirit of Manitoba. Pi Engineering’s Darryl Stoyko, a proud Manitoban, loved to tell the story of his own connection to Golden Boy as a student at the University of Manitoba. It all started when the Manitoba government set out to repair and restore Golden Boy, unaware that it required anything more than a re-gilding. The restoration p ..read more

What’s the deal with pipe stress? Well, the truth is that pipe stress is the last thing we think about before completing a file. Every pipe connects various pieces of process equipment to form a system. Those vessels, tanks, exchangers, pumps, and compressors all come with limits to piping loads on the equipment nozzles, eg., API 610 for pumps, API 650 for tanks, API 617 for compressors…and so on. Since these are typically quite sensitive, that is usually the first thing we do, make sure the piping layout, and restraints result in piping loads within those limits. Then we make sure there are g ..read more

Darryl Keith Stoyko Ph.D., P.Eng., P.E. September 10, 1979 ~ November 3, 2022 Darryl recently celebrated his 5 year anniversary with Pi, and we had hoped for many more years. His passing in early November has had a profound effect on everyone here. He is dearly missed. His presence inspired and motivated us to reach higher standards of excellence. His combined talents in Fitness-For-Service assessments, FEA, CFD, Vibration, and Electronics led to building in-house custom data recorder boxes to record and store a highly flexible set of data; strain gauging, vibration sensors, pressure sensors ..read more

This video shows the temperature field developed during the first pass of a five-pass field girth weld in a coupling.  The intent of the simulation was to demonstrate that the temperature of the inner wall parent pipe did not exceed the melting temperature of the liner that was shop installed after the coupling was fillet welded to the pipe.  It is interesting to observe that the melting temperature of the steel was accurately predicted.  This particular simulation made use of element activation, programming a heat flux input to simulate the heat input from ..read more

Dynamic surface loading is often overlooked when designing a pipeline.  There are a number of situations where your pipeline might be exposed to surface loads that weren’t anticipated at the design stage.  Examples that we have encountered in practice include: unplanned temporary or permanent crossings that arise after construction construction activities associated with pipeline integrity operations construction activities associated with the installation of other infrastructure near existing pipelines mechanized compaction activities over newly installed pipelines ..read more

“An ounce of prevention is worth a pound of cure” Benjamin Franklin In-line inspections (ILIs) and integrity digs are two critical components of routine buried pipeline maintenance and integrity programs. In-line inspections can yield much information about a pipeline’s health, including quantifying progressive pipeline movement as well as identifying a large variety of defects including pitting, cracks, out-of-roundness, dents, local wrinkling or global buckling. Closely related to in-line inspections are integrity digs, which are planned excavations to expose sections of the pipeline ..read more

We get it.  Sometimes your shiny new pressure-containing equipment doesn’t stay shiny or new for any number of reasons; it may be in service in a corrosive environment, developed a crack, has been put into a new service due to a change in operating process, or just plain suffered a “Bubba stain.”  For whatever reason, your pressure containing equipment no longer meets the construction tolerances or requirements of the original code of construction. While replace-in-kind is often an option, this is sometimes not the preferred option due to down-time, procurement related challenges, or ..read more
