Your Selection Guide to Pipe Test Plugs
Piping and plumbing inspections are crucial. They come in handy for new construction or routine maintenance procedures like checking for corrosion, leaks, and other damages. When this happens, plumbers will often rely on a range of tools to aid their inspections. Plumbing or pipe test plugs are some of the most helpful equipment for such applications. The devices or equipment are designed to seal each end of the tested pipe, ensuring the rest of the pipeline or piping system remains undisturbed throughout the testing process. However, pipe test plugs come in an array of options to suit different requirements. Here are a few quick tips to help you know which one to choose.
Mechanical Or Pneumatic
Mechanical and pneumatic or hydraulic test plugs are the primary options you will find in the markets. Therefore, it's worth knowing a thing or two regarding how they work to determine the best for your application. Your choice may come down to your need for the test lung. For instance, you may need to block a plumbing line or pipe. For such applications, go for mechanical test plugs.
On the other hand, pneumatic plugs are inflatable (with water or air), making them ideal for leak detection, pressure-testing new pipes, bypassing, etc. However, since pneumatic test plugs are inflatable, they are usually meant for short-term uses as the inflation pressure reduces over time. Therefore, when using pneumatic test plugs, the inflation pressure must be monitored and adjusted every few hours. Also, it's crucial to maintain the ideal pressure for optimal results and avoid under-inflation or over-inflation.
Size And Shape
Just like pipes have different shapes and sizes, the test plugs designed to seal or block them also come in various sizes and shapes. Therefore, get the measurements of your pipes, particularly the diameter. Using the wrongly sized test plug can result in inaccurate results, and you risk damaging your pipes in the process. For unconventional pipe configurations or shapes like rectangular openings, you may be able to get custom test plugs, although they may cost you slightly more than standard shaped plugs.
Pressure Rating
Like size, your test plugs can only hold up to a maximum amount of pressure. For safety reasons and to avoid damages to the plug, choose one that can withstand the maximum pressure of the content inside the tested pipes.
Material
Pipe test plugs also come in many different material options. Personal preference, cost, and the environment will help you choose the correct material. For instance, nylon may be the more affordable option than PVC but not as durable. For lightweight applications, consider options like aluminium. Therefore, consider aspects like corrosiveness, temperature, pressure, etc., and choose a material that is insusceptible to damage under such conditions.
