Out of all the different flow management tools that you could choose for your system, none provides the versatility and accuracy of the Parshall flume. These flumes can be installed in a variety of applications, and when cared for correctly, should consistently perform the way that you need and deserve.
While there are several questions that people have when thinking about installing a Parshall flume, the most common is how long their flume will last. Unfortunately, there is no simple answer to this question, as the lifespan of a Parshall flume can depend on several factors. Here are a few tips to help you determine your Parshall flume lifespan and advice for making this useful tool last as long as possible.
What’s Your Material?
There are several factors that play into Parshall flume lifespan, but the most important issue is the material from which your flume was constructed. Generally, Parshall flumes will be constructed from stainless steel, galvanized steel, or fiberglass, and each of these materials will have individual lifespans.
Under normal flow circumstances, one of the longest lasting of Parshall flume materials is stainless steel. Stainless steel generally holds up well under tough conditions and should last for multiple decades. However, in applications where corrosion is likely, the lifespan of stainless steel flumes will be shorter.
Fiberglass flumes are nearly as long-lasting as stainless steel flumes, and in many cases, may be the better option. Typically, a fiberglass flume will last for twenty years or more and resists UV damage better than almost any other flume material. Unlike metal flumes, fiberglass flumes are not at risk for corrosion. However, when the flow has grit, it can scrape away the laminate used in fiberglass flumes and reduce their lifespan.
When cost is a concern, many people choose galvanized steel flumes. While they are more affordable than other flume types, galvanized steel flumes have significantly shorter lifespans, and are at high risk for corrosion.
What Causes Corrosion?
If you choose a stainless steel or galvanized steel flume, you should be prepared to deal with corrosion, which can be caused by several factors. For instance, gases in your flow can cause tremendous corrosion, particularly if there is high oxygen content. Hard water, meaning water that contains high mineral content, can also cause corrosion in metal flumes. If you suspect your flume will be exposed to corrosive materials, fiberglass is the best choice.
While there are several threats to the lifespan of your flume, keeping your flume in tip-top shape can be as easy as having your operators perform regular maintenance. Make sure that your operators are frequently checking your flumes for signs of damages and are taking steps to correct his damage when detected. By scheduling regular maintenance, you should be able to boost your flume’s lifespan.
