Market Outlook 2012: The Winds of Change

vmfall11_market_outlook

Attendees at this year’s VMA Market Outlook walked into the meeting room with a bit of shell shock. The stock market fluctuated wildly in the days leading up to the Aug. 11-12 event in Boston following weeks of tough U.S. federal budget negotiations and the downgrading of the U.S. credit rating for the first time in history. Sara Johnson, senior research director of IHS Global Insight, called the events “headwinds” blowing against what had been expected. She said the year 2011 had been filled with such unusual occurrences, including the Japanese earthquake/tsunami earlier that year as well as other natural disasters and political upheavals.


SIL Made Simple

A good deal of misunderstanding exists about what an SIL is and how it is assigned. Yet anyone involved in products that are to be used in Safety Instrumented Systems should know how this designation came to be and what it means.

Extreme Valve Testing

Valves today face more challenging conditions from a wider range of applications. As a result, users are asking for more and better testing.

Filling a valve up with water, adding pressure and looking for leaks might work for some valve specifications, but many of today’s demanding valve requirements call for much more stringent testing and evaluation. Special service applications such as hazardous fluids, nuclear power plants, high-pressure pipelines and more dictate a much broader testing and inspection regimen than traditional simple tests.

Materials Selection for Deepwater Gate Valves

With the discovery of oil and gas in water depths thousands of feet below the surface, selection of valves is more important, difficult and complicated. Gate valves, which are often used in subsea applications, are available today in a wide selection of materials, but choosing them requires knowledge of new challenges and established standards.
