Engineering Case Histories: Case 107: Weld failures in vibrating equipment

Sofronas, A., Consulting Engineer

Vibrating equipment can be machines, such as vibrating screens, conveyor pans or a combination of both, that are designed to transport, sort or dry materials.

Engineering Case Histories: Case 106: Delayed fireball type explosions

Sofronas, A., Consulting Engineer

When a vessel containing a flammable liquid under pressure (such as those in an LNG road tanker truck) ruptures and ignites, a vapor fireball explosion can occur.

Engineering Case Histories: Case 105—Temperature distribution along a flare line

Sofronas, A., Consulting Engineer

During an engineer’s career, many interesting questions come up that may not have a ready or good answer.

Engineering Case Histories—Case 104: Energy in steam boiler explosions

Sofronas, A., Consulting Engineer

Steam boiler explosions happen all over the world, as an internet search will reveal.

Engineering Case Histories: Case 103—Addressing heat exchanger tube leaks

Sofronas, A., Consulting Engineer

Heat exchangers have multiple tubes with fluid passing through and over them that either heats or cools another fluid.

Engineering Case Histories: Case 102—Use caution when specifying a safe hydrotesting distance

Sofronas, A., Consulting Engineer

Hydrotesting is performed on piping and vessels to verify their integrity.

Engineering Case Histories: Case 101: Preventing crankshaft failures in large reciprocating engines

Sofronas, A., Consulting Engineer

The gas processing and pipeline industries use many integral gas engine reciprocating compressors with crankshafts more than 20 ft long.

Engineering Case Histories: Case 100—Was sloshing the cause of a failure?

Sofronas, A., Consulting Engineer

Some situations in failure analysis demand an understanding of the wave motion of a liquid wave in a tank, called “sloshing.”

Engineering Case Histories—Case 99: Pooling knowledge and experience builds personal and team success

Sofronas, A., Consulting Engineer

With the help of an excellent mentor, I became adept at analyzing equipment and structures at the start of my career, using analytical techniques.

Engineering Case Histories: Case 98—Why performing calculations is important to an engineer’s career

Sofronas, A., Consulting Engineer

Engineering calculations can help an engineer’s career by controlling the risks taken. The author has followed this path.
