Performing maintenance tasks correctly the first time has become increasingly important to end users. Today’s end users are tasked with doing more work with less time, fewer resources and smaller staffs while responding to the increase in environmental and other equipment-related pressures.

The criteria for expansion joint selection for fluid piping applications focuses on the expansion joint’s quality, durability and capabilities. To ensure that the rubber expansion joint’s installation provides optimal service life, operators and maintenance personnel must consider specific conditions and take a systematic approach.

Many associations, societies and regulatory agencies have rewritten and redeveloped emissions and leakage standards and controls year after year.

When discussing expansion joint selection, the conversation typically focuses on the quality, durability and capabilities of the expansion joint. However, the expansion joint’s role in the overall energy efficiency and optimization of the piping system is often overlooked.

High performance liquid chromatography (HPLC) is a chemical analysis technique with wide applications, from food and medical safety to manufacturing. HPLC can detect vitamin D levels in blood serum or performance enhancing drugs in urine. The technique has even been used to synthesize blood and determine DNA evidence in forensic investigations.

Within the oil and gas industry, the rotating shafts of equipment—such as pumps, motors, compressors, gearboxes and turbines—perform an essential function in both upstream and downstream applications. This rotating equipment ensures process flow and the safety of employees and the surrounding community.

One of the oldest sealing devices, compression packing is still very common in modern industries such as oil and gas, petrochemical, agriculture, pulp and paper, power generation, and mining. Compression packing is made from a range of soft and pliable fibrous yarn materials—from vegetable and animal fiber to many high-performance synthetic fibers.

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.

Last year, “Reduce Thrust and Extend Bearing Life” (Pumps & Systems, December 2013) discussed the benefits and some potential pitfalls of adjusting the axial clearance of American National Standards Ins

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

Since its Nov. 27 meeting, the Organization of Petroleum Exporting Countries (OPEC) has witnessed even more turbulence in the oil market. Prices have dipped as low as little more than $60 per barrel.

My previous two columns have described assessing a system that does not use controls. In the first part (Pumps & Systems, October 2014) the assessment process was detailed. Last month, I covered performing the system calculations (Pumps & Systems, November 2014).
