When you need to check the condition of your underground pipes and pipelines, you may consider using pipe testing machines. The machine is easy to install, and works perfectly in all types of conditions. It ensures that all the joints are tight, and also that there are no leaks in the pipe walls. You can carry out all sorts of tests without the hassle of digging up the entire trench.
Pipe testing machine is designed to ensure correct installation and proper functioning of drainage systems, sewage pipelines, water pipes and central-stack waste pipes. It helps in checking the pipe joints, flow, temperature, strain, temperature and other vital parameters like load-bearing capacity and resistance. The machine has various options in its working. It can test both long and short pieces and can check the pipe walls. The device has the ability to measure the inner diameter, inner length, cross-section and surface texture in the concrete pipe or the steel pipe.
In the process of inspecting the pipe joints, the machine comes into play by mounting clamping plate 11 in the open position. The clamping plate 11 has one-way valve which allows the flow of gases to be regulated. The valve can close if there is no or insufficient flow. The two other types of clamps which are manually and electrically operable are fixed-clamp and screw clamping.
The third type of pipe is the rotary pipe. This is often used for drainage systems. The rotary pipe is similar to that of a water pipe where the bottom of the rotating cylinder and the pipe bed are both enclosed in a cylinder skirt. The gas travels in the form of a jet while going through the pipe and it is usually recovered via a rotary vane or hydraulic piston in the bed. This is one of the most commonly used testing machines since it is able to test both liquids and gases with high accuracy.
The fourth type is known as the dynamic line test machine. This is one of the most commonly used testing devices for testing both cold and hot water pipes. It works by subjecting the end of the piping to the high pressure and cold temperatures to ascertain the stress level of both ends. The pressure applied may either be static or dynamic pressure.
Lastly, the last type of hydrostatic testing machines is known as dynamic pressure measuring device or DPM. This uses a pump driven by an electric motor to inject water into the pipes. When the flow of water is detected, a computer display shows the pressure change that took place. It is normally used to measure flow variation in the pipes as opposed to pressure changes.
