A deflection gauge is used in pipelines to determine if the line is functioning properly. The gauge can determine if the line has any blockages or if the pipe has taken any damage. If a pipe is not perfectly round, this can cause backup issues or increased stress on the pipe once liquid is in it. These kinds of issues are what commonly cause a pipe to crack and break. Deflection gauges are available to prevent that from happening. However, there are many different types of gauges and you need to be sure to get the correct gauge for the pipe. There are certain requirements your pipe has to pass when you test it, so be sure to know those before you purchase a gauge.
Multi Size Gauges
A multi size gauge is perfect for pipelines that have different size pipes. This gauge can come in a couple of sizes and allows you to swap out and change the size if needed. It does not automatically fit to your pipe though, so you will have to take it out and adjust it every time your pipe size changes.
Steel and Aluminum Gauges
These deflection gauges are made of steel or aluminum, depending on which you choose. The aluminum gauge is significantly lighter and therefore can be used for a quick test. However, since a steel gauge is heavier, it can easily find imperfections in the pipe that you might miss with the faster, lighter aluminum gauge.
Bullet Style Gauges
A bullet gauge, as you might guess, is for quick and accurate tests. The gauge is shaped differently from any other gauge and looks similar to a bullet in its design. This makes it ideal for pipes with tight turns or generally small pipelines. Its different design means that it can go much faster than most gauges and is less likely to get stuck. It is also built with aluminum, making it lightweight as well as fast.
Split Type Gauges
If you have a very large diameter pipeline, you need a split type gauge. This kind of gauge is ideal for large pipes because it can be broken apart into smaller pieces and reassembled. This allows it to fit through manhole openings and still be used in large pipes. It typically breaks apart into four or five pieces and the pieces are easily put back together once in the pipeline.
It is important to test all pipelines before you put liquid in them. If you do not test it and your pipe breaks, it could be disastrous for anyone or anything in the area.
