A method for quantifying pipe vibrations
Failures of piping due to vibration-induced fatigue are a serious problem in the chemical process industries (CPI) and a matter of concern for the safety and reliability of plant operations. Due to the complexity of flow-induced vibrations in pipes, no closed-form design solutions — those that can be expressed in terms of well-known functions — are available. In this article, we present a...

Tubing for peristaltic dosing pumps
Peristaltic pumps work by compressing a tube against a circular pump housing with rollers on a rotating arm. The fluid that is ahead of the roller gets pushed forward, while new fluid is drawn into the tube by the vacuum generated as the tube returns to its relaxed state. Peristaltic pumps are a type of positive displacement pump that can be used in industrial chemical dosing applications and others...

Piping: Minimizing the Risk of 'Pre-buys'
To stay on budget, major capital projects often call for aggressive schedules. Engineering, procurement and construction (EPC) contractors often end up using work processes that are not part of an established or standard work procedure. This is especially true when it comes to acquiring materials to support the schedule, particularly for critical paths related to the piping design, supply, fabricate and...
