Hydrostatic pressure testing is essential for a variety of reasons. This type of testing, when performed properly, will determine if there are any problems with a pipe or fitting, it can identify the exact location of any leaks or cracks in a structure and it can help to pinpoint the source of a pressure fluctuation. A variety of different instruments are used during hydrostatic pressure testing. These instruments vary in terms of both complexity and utility and are used in a wide range of applications. Let’s take a closer look at some of the instruments commonly used for this type of testing.
A visual hydrostatic pressure test is one of the simplest and most cost effective ways to test the integrity of a pipeline or fitting. The instruments used for visual hydrostatic pressure testing consist of an inexpensive handheld digital instrument, such as a pen-based meter reader or an LCD display that is set up with a computer. This tool can be used to test the ground water level, or can be used to test the discharge of any liquid from a specific vessel or fitting.
Another type of hydrostatic pressure testing instrument is the portable Horizontal Line Flux Gauge (HLG), which can often be manually operated. The HGH is connected to a specific area through a flexible hose that is stretched along the surface to be tested. The probe of the HGH is gently pressed into the surface to be tested, and its position, orientation and depth of penetration can be recorded. This type of hydrostatic pressure testing device is commonly used for underground pipes or disposal wells. The instrument is capable of detecting the exact degree of saturation and can show a good indication of the pipe’s internal diameter and length. There are also some models of HGH that incorporate automatic pressure relief.
A computerized hydrostatic monitor is the next most popular type of hydrostatic tool. In essence, this is an electronic device used to record the pressure within an underground pipeline. Generally, this device comprises a computer control unit, an external tap or regulator and a couple of probes, which are used to detect the changes in pressure. The computer can integrate this data with other types of information to create a complete picture of the pipe in question.
The last type of pipe-monitoring device is the Hydrostatic Pressure Alarm. This device is used to detect any impending leak. It works on the principle that a certain level of pressure will always exist beneath any surface, including water, and it is caused by the natural dissipation process of the soil around the pipes. This alarm is set off when any change in the pressure detected by it occurs. Usually, this type of alarm works with the help of an external tap or regulator, as well as a battery-powered vibrator.
There are many different manufacturers in the market that offer various types of hydrostatic pressure monitors. A customer needs to find out the name of the manufacturer that s/he intends to buy the monitor from, the years of experience that the brand has in the industry, and the feedbacks from customers who have previously bought the same monitor from the same manufacturer. From this information, a customer should be able to gauge whether a particular brand is worth buying or not. Moreover, a person also needs to be aware of the types of measurements used to determine the hydraulic pressure of a pipe. In order to conduct an accurate reading of the pressure, one needs to consult an expert technician for hydrostatic pressure testing.
