Armstrong makes a wide variety of flow meters to meet the needs of nearly any application, but which one is right for your specific needs? Here’s a quick guide that covers key aspects to consider such as: Line Size Permanent Pressure Loss Accuracy of Flow Coefficient Required Straight Run of Piping Rangability What Fluid/Gas is […]
In the following pie chart, which of the following two are responsible for the highest expense and the least expense when it comes to generating steam? Fuel (highest) and Depreciation (least)Direct Compensation (highest) and Property Tax (least)Electricity (highest) and Environmental Waste Control (least)Fuel (highest) and Water (least)Repairs/Improvements (highest) and Supplies (least) And the answer is… 4. Fuel and Water Fuel is the most expensive part of producing […]
Thank you to everyone who attended our 80th Anniversary Customer Appreciation Celebration on September 8th. It was incredible to see so many of the people we’ve gotten to know so well over the years in one place. It was 1937 when Campbell-Sevey originated our company as the Hoyt A. Sevey Company. 80 years later we […]
Shannon insulation blankets, covers and jackets are designed for conserving energy and thermal efficiency. In a recent case study they supplied Albany Medical Center’s district heating system, in Albany, NY, with a self-contained insulation system. Initially, the medical center purchased reusable blankets as part of a pilot project for steam components within a single mechanical […]
Benchmarking the fuel cost of steam generation, in dollars per 1,000 pounds ($/1,000 lb) of steam, is an effective way to assess the efficiency of your steam system. This cost is dependent upon fuel type, unit fuel cost, boiler efficiency, feedwater temperature, and steam pressure. This calculation provides a good first approximation for the cost […]
A system of compressors powered by surface condensing steam turbines is inherent in the operation of a typical ethane cracker unit. These turbines run by extracting work from high-pressure steam, while a surface condenser condenses the turbine’s exhaust to both maximize compressor horsepower and recover valuable condensate. In an ethane cracking unit, a troubleshooting study […]

Steam losses are typically calculated using one of two well known formulas. What is the name of the formula illustrated on the right? Napier’s Formula Campbellseveyian Formula Hoytan’s Formula Masoneilan’s Formula Brianrossian’s Formula And the answer is… 5. Masoneilan’s Formula The two most commonly used formula’s to calculate steam loss are Masoneilan’s and Napier’s. If […]
Though straight runs of piping are normally insulated, in a typical steam system, radiant heat escapes from exposed valves, strainers, and steam traps, causing the loss of thermal energy. With just one Gate Valve equal to the surface area of 5 linear feet of pipe, those surface areas add up quickly, creating energy losses as […]
There is nothing like a solar eclipse to get the Campbell-Sevey team out of our offices . . . and staring up at the clouds. Because the last total solar eclipse in the US happened in 1979, last Monday the team was excited to see one of nature’s most awe inspiring events. With Charlie Thomas […]
