Latest Piping Articles

I received a lot of feedback on my column “How Much Energy Do Pipes Remove?” in the September issue of Pumps & Systems

Last month’s column discussed the pre-screening process that identifies and prioritizes systems with a high probability of significant energy savings.

In sewage grinder pumps, domestic wastewater from one or a few households flows by gravitation to a pumping station equipped with one or two grinder pumps, having a discharge pipe of nominal diame

In past “Pumping Prescriptions” columns this year, I have discussed the procedure of piping size selection when given the process flow requirement and how this affects the pump’s power consumption

Part One of this series (Pumps & Systems, August 2014), discussed the new American National Standards Institute/Hydraulic Institute (ANSI/HI 9.8) design standard requirements.

When discussing expansion joint selection, the conversation typically focuses on the quality, durability and capabilities of the expansion joint.

Last month’s column described the process of creating an energy cost balance sheet for a piping system (see Figure 1).

Piping plans for mechanical seals are used to improve the environmental conditions around a seal, extend its capabilities and allow operators to monitor seal performance.

My last column (Pumps & Systems, April 2014) explained why resistance in implementing pump system impro

For those of you old enough to remember Lawrence Welk, you’ll notice that the title of this brief column is the final quote from his show’s closing song. I am still a loyal fan of his reruns today.

Part 1 of this series (Pumps & Systems, March 2015) discussed what happens to a boiler feedwater (BFW) pump during plant transients.

A reciprocating power pump, as depicted in Figure 1, is a displacement machine. It has characteristics that are different than a centrifugal pump.

In today’s high-volume pumping applications, energy efficiency and cost control are more important than ever.

Last month's column (Pumps & Systems, February 2014) reviewed the pump selection process and described how many users oversize pumps by adding design margins to account for unknown conditions present during the pump specification process.
