Superstorm Sandy made landfall Oct. 29, 2012 on the eastern seaboard of the United States, resulting in unprecedented flooding in the New York City metropolitan area. Flood levels zoomed past the previous record of 10 feet in the southern portion of Manhattan to reach 14 feet, and wave heights in New York Harbor were measured as high as 32 feet.

A universal issue that comes up at almost any event today is the need to attract new people with the right skills into the specialized, technical fields where valves and control devices are made and used. But to solve that problem requires something that many of those doing the hiring and training don’t have: an understanding of the differences between the generations of yesterday and those of tomorrow.

The combination of North American shale fields that continue to fuel high levels of new domestic oil and gas projects and ongoing global efforts means the need for efficiency in instrumentation selection has never been higher. To drive efficient work processes with a younger, less experienced workforce requires an understanding of regulator and control valve functionality, an understanding that will lead to optimal selection in minimal time. This article is intended to address these issues.

Almost every day we read about a cybersecurity breach of a major bank, retailer or government computing system. These attacks have become so commonplace we are no longer surprised by what we read. In fact, a recent panel of top-level security experts from industry, military and government concluded that “the threat posed by cyberattacks targeting U.S. critical infrastructure and private industry now outweighs any other national security threat.”1

Because flanges allow the assembly and maintenance of system components without the need for cutting and welding pipe, they play an important role in piping systems. However, the structural integrity and leak tightness of waterworks piping systems are only as strong as the weakest element, which often is the flange connection between various valves and fittings. Yet because piping systems are subject to many types of loads and are constructed of a variety of materials, understanding and predicting the rating and performance of those flange connections is difficult. This is further complicated by the fact that different sealing mechanisms such as gaskets, O-rings and mechanical seals can significantly affect the performance of the connections. As far as ratings, ASME B16.1 lists pressure ratings for Class 125 flanges from 50 to 200 psig depending on size, material and temperature.
