Two decades ago, EST Associates, Inc. started operations in Needham, Mass., to provide the New England area with environmental sampling and related monitoring services.
Driven by the demands of a growing customer base including engineering and consulting firms, remediation contractors, local municipalities and wide ranging industries, EST has expanded its capabilities to a new selection of O&M services, site remediation and pipeline inspection programs. John Carlin, president and owner, credits the company's 20 percent growth in profitability during the past few years to EST's ability to capitalize on the area's growing needs.

Massive amounts of energy are used to transfer oil and refined products over long distances. In the United States, several long distance pipelines move gasoline from the refineries in the Southwest to the coastal areas in the Northeast. Pipelines are an efficient, quick, reliable and economic method compared to trucking or boats.

With production time and cash flow at an all time premium, more companies are looking for time and cost saving alternatives to replacing slightly damaged assets. In a refinery, for example, it is common to encounter a leak from a hole in a carbon steel pipe. This may initially seem like a simple repair, which would normally be fixed by cutting the old leaking section of the pipe and welding in a new section. The majority of the time, it is not that straightforward.

Consider a typical ANSI-dimensioned 1x1.5-6 pump, as discussed in the P&S August article. The performance curve showed the BEP flow at around 100 gpm. The ANSI designation 1x1.5 means that the discharge flange is 1 in and suction 1.5 in. Why and how do manufacturers select such dimensions for a particular flow rating? Why did they not select and base their performance coverage charts on a 3x4-8 size for the 100 gpm?

About 900 years before Newton formulated his universal gravitational theory, the Greek philosopher Aristotle espoused something different. He believed that all things had a natural place in the universe, so any object that fell to the earth did so because it had a "need" to return to its natural place. He further theorized that heavier objects would fall faster than lighter ones because they had an even greater need to return. We know now that his theory was a bit off the mark, but had he adapted it to corrosion, it could have described the process quite well.

Infrastructure is in the headlines again thanks to the Obama Administration and its strategy to help create jobs by rebuilding the nation's roads, bridges and water systems. In fact, renewed interest in infrastructure is so high the American Society of Civil Engineers (ASCE) moved up the release of its Report Card for America's Infrastructure. Unfortunately, the news was not good.

If any silver linings exist for the economic crisis that has gripped the United States since last summer, one is the heightened public and governmental awareness about the nation's need for infrastructure improvements-a situation that American industry had watched grow without proper attention in recent years.

Have you ever wondered why the pressure exerted by a column of liquid has absolutely nothing to do with its volume or, for that matter, the geometric shape of its container?
