Pump Selection
The Pump Centre

<<Pump selection is regarded by many engineers as a black art and they are only too happy to pass on as much of this task as possible to the prospective pump supplier or manufacturer. Using a manufacturer that has vast experience of pumps and undertakes similar selection procedures on a daily basis is a sensible strategy for saving valuable time and money. The major strength or weakness of this selection partnership is "communication" - making sure the manufacturer knows exactly what the pump is expected to do. For successful pump selection purchasing engineers must be clear in their own mind what they want and why they want it. They must complete a specification document including a suitable data sheet and system drawings. It is important that they have a good feel for what generic type of pump they require so that approaches are made to manufacturers who have suitable products to offer. Also they must be able to assess the relative merits of competitive bids from different suppliers. The needs and characteristics of the pumping system determine what pumps can be used. The guidelines given below address the issues that every engineer should consider before purchasing a pump. >>

Vertiline Case Histories - Innovative Pipeline Evaluation and Repair
Baker Hughes Incorporated

<<Operators now recognize that a high number of their failures occur in the shorter and/or small-diameter pipelines, many of which were considered "un-piggable" by the industry. As the frequency and cost of failures in this category are realized, it becomes apparent to operators that all failures, regardless of pipeline size and length, can create significant risk exposure and expense to their companies. Most pipeline operators are unaware of the tethered, magnetic flux leakage inspection system specifically designed by Baker Atlas for the shorter, small-diameter pipelines. Typical application for this service includes oil and gas production flowlines, product lines, river crossings, refineries, and industrial and municipal piping. Since most of these types of pipelines are not equipped with launchers or receivers, the tethered inspection system is ideally suited. >>

Investment-Grade Compressed Air System Audit, Analysis, and Upgrade in a Pulp and Paper Mill
Unicade Inc.

<<An investment-grade compressed air audit, analysis, design, and upgrade in an industrial facility requires a thorough understudying of original design basis, current problem definition, goal settings, load assessment, base case model development, and an ability to conduct unlimited "what if" analysis to determine the cost-effective efficiency improvement measures. Most successful projects are justified using energy savings and non-energy benefits. A life-cycle cost analysis will help the customer focus on cost of owning, operating, and maintaining the compressed air motor system over it's useful life. A software application that easily integrates and calculates interactive impact of process and mechanical variables on electric power use would be of immense help in conducting such "systems analysis" of motor systems. This article presents a real-life successful project, with an investment of about $0.75 million dollars, documented energy savings of 2,935,000 kWh/year, and other non-energy benefits that eventually justified the project.

Plumbers, Pipefitters, and Steamfitters - Job Statistics U.S. Department of Labor

<<Most people are familiar with plumbers who come to their home to unclog a drain or install an appliance. In addition to these activities, however, plumbers, pipefitters, and steamfitters install, maintain, and repair many different types of pipe systems. For example, some systems move water to a municipal water treatment plant and then to residential, commercial, and public buildings. Other systems dispose of waste, provide gas to stoves and furnaces, or supply air-conditioning. Pipe systems in power plants carry the steam that powers huge turbines. Pipes also are used in manufacturing plants to move material through the production process.>> Received on Mon Jan 22 18:57:00 2001
