The UTSP-0100 Concrete Pipe Testing Machine is made to specifically complete crushing tests on drain and sewer pipes, concrete pipes, fixtures, valves, adapters, pre-fit accessories and pre-cast sections. The machine is able to test pipe components, both in closed and open positions. It can be utilized for underground pipes with a Length of more than 3000mm. When the machine passes through an obstruction, it will leave an impression on the pipe, usually referred to as a strike.
A high-pressure version of the machine is the UTSP-EKMS, which is especially useful in determining the flow capacity of underground pipes. The device is made up of two main components namely, the hydraulic piston assembly and the hydrostatic hose. The hydraulic piston assembly consists of a cylinder and ring gearbox. The hydrostatic hose has a tapered inner diameter and a tapered outer diameter.
The pipe testing machine comprises of various accessories. These accessories are helpful for different types of testing including hydraulic compression, hydrostatic pressure and tensile strength. These accessories include the probe for the soil, the clamp for handling pipes and the cut throat for cutting concrete pipe. The clamp is placed over one end of the pipe and clamped at the other end. The cut throat consists of a steel cylinder that is pushed into the pipe, from one end.
There are three types of hydrostatic pipe testing machines. These are the single stage machine, the two-stage machine and the multi-stage machine. The single stage machine is very similar to the UTSP-0100 but only the second stage is used here. This machine is considered to be the best for checking the pipe pressures. On the other hand, the two-stage machines can only measure the pressures and not for checking the tensile strengths.
The Multi-stage machine comes in various sizes and the most commonly used is the 40-inch pipe. All the pipes in a construction are treated equally and hence the equipments are of equal sizes. When it comes to choosing the right machine, the operator has to consider the capacity of the bore. If the capacity of the bore is greater than four hundred pounds, then better quality and better testing machines are required. The criterion to judge the size of the machine is the hydrostatic pressure obtained after five minutes of compression. If the pressure of the bore is less than four hundred pounds, then smaller machines can be selected.
A hydrostatic testing machine should have a control system that gives the operator easy access to the tested pipes. The control system has to be able to indicate if the test was successful or not. There are some optional accessories that can be added to the machine, like the measurement of the stress radii, etc.
