Hydrostatic test method: The hydrostatic test method for plastic pipes in water conservancy projects is mainly to sample plastic pipes within a specified time under a constant hydrostatic state. In the process of sampling, it is necessary to strictly implement the relevant regulations in the "Internal Pressure Resistance Test Method of Thermoplastic Plastic Pipes for Fluid Transport" promulgated by the relevant departments of our country. First, the tested pipe samples filled with water need to be put into the experiment. In the water tank, the temperature of the water tank is adjusted according to the tested pipe samples in the experiment. In the process of experiment, it is necessary to subdivide the medium in the pipe hydrostatic experiment into water, air or other liquids according to the experimental standard of hydrostatic pressure. At the same time, during the hydrostatic experiment of plastic pipes, it is necessary to accurately record the specific experimental phenomena of the pipe under test. After the pipe to be tested reaches the specified time for the experiment, the experimenter needs to observe whether the pipe under test is damaged by hydrostatic pressure. I found that the pipe under test was broken or leaked too much during the experiment, so the experimenter should analyze the specific reasons for the damage of the pipe.
Elongation at break testing method: The testing method for elongation at break of plastic pipes in water conservancy projects is mainly to check the physical properties of plastic pipes and fittings. In the process of testing the elongation at break, the experimenter needs to strictly implement the relevant requirements in the "Determination of Tensile Properties of Thermoplastic Pipes" promulgated by the relevant departments of our country. During the testing process, the testing temperature needs to be maintained at Between 20°C and 23°C, the pipe under test needs to be placed on the experimental machine for tensile experiments at different rates, and according to the experimental results, it is necessary to analyze whether each plastic pipe fitting is subject to fracture problems during the fracture tensile test. The specific reason is that in this way, we can have a clear understanding of the tensile properties of plastic pipes in the application process of water conservancy projects, so as to ensure the safety of water conservancy project construction. Vicat thermal deformation detection method: In the process of Vicat thermal deformation detection of plastic pipes in water conservancy projects, it is mainly to detect the heat resistance of plastic pipes in the application process. The grades in heat resistance performance are accurately divided. In the process of Vicat thermal deformation detection, the inspectors need to strictly implement the relevant requirements of "Determination of Vicat Softening Temperature of Thermoplastic Pipes and Fittings" promulgated by relevant departments in my country. During the Vicat heat deformation experiment, if the temperature that the pipe can reach during the experiment is higher, it means that the thermal stabilization effect of the plastic pipe fitting is better. On the contrary, it means that the thermal stabilization effect of the plastic pipe fitting is poor.
