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.

In the United States and around the world, industrial processers are striving to do more with less—to maximize efficiency, minimize costs and remain compliant with increasingly stringent regulations governing operations and output. The need for higher production at lower cost is especially pronounced within the power market. Producers must balance the growing demand for energy with the changing regulatory environment, while the traditional methods of power production, such as coal-fired power, face challenges that threaten their future viability.

Natural gas returned as star of the show at the 2014 VMA Market Outlook Aug. 14-15 in Boston, but it shared the stage this year with oil. Speakers said those two commodities promise to alter the flow of trade around the world and rebuild the North American economy. Speakers also said the economy has met the expectations for growth that many predicted would finally bury the Great Recession in the past.
