Seals

Latest Seals Articles

In the U.S. and abroad, governments, regulators and third-party activist groups are considering policies and actions that could have implications for the sealing device industry. The passing of the Clean Air Act in the early 1990s was a watershed moment for the industry.

Dry containment seals provide enhanced safety and control of emissions. When coupled with the appropriate piping plans, they can provide early detection of sealing performance deterioration and trigger an alarm if the seal fails.

Climate has an often ignored impact on sealing systems. Damage from harsh weather conditions, such as intermittent storms or humidity, can be effectively managed. But daily exposure to the outdoors, especially where extreme temperatures are the norm, can wreak havoc on seals.

Gaskets are crushed more frequently than many end users realize. Some maintenance professionals claim that is all they see when they separate a leaking flange. Many simply replace the gasket rather than investigating the cause of the failure in depth.

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.

Columns

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.

In this two-part series, how transient events in process equipment affect other system components will be discussed. Part 1 covers how deaerators (DAs) may be affected by generator trips and how these deaerator transients may also affect system pumps.

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