Hdpe, There are standards that are determined from the beginning to the end of Hdpe pipe production and which must be applied. And these tests are applied. PE 100 pipes can only be shipped and transported after these tests.
- Thermal Stability (DETERMINATION OF OXIDATION INDUCTION TIME) Test
It is the time that the antioxidant additive in the PE material prevents oxidation at high temperature.
- Carbon Black Amount Analysis (ISO 6964)
It is made by determining the amount of carbon (%) added in order to make the Hdpe pipes resistant to UV rays.
- Density Test (ISO 1183)
It is made with the aim of calculating the weight of the Hdpe pipe per unit volume. The sample is weighed first in air and then in a liquid whose density is known beforehand. Density is also found with the calculation specified in the standard.
- MFR (Melt Flow Rate) Test (ISO 1133)
It is an application made to test the behavior of the material to be used against temperature before it is processed. The values found as a result of the test with the MFI device were loaded into the device and calculated gr/10 min. The result is determined with the unit.
- Tensile Strength (ISO 527)
Thermoplastic and profile pipes flow or max. It includes the determination of tensile stress and elongation at break at load. The test for tensile properties is carried out to determine the properties used in manufacturing and is valid for all thermoplastic pipes.
- Hydrostatic Pressure Test (ISO 9080 EN 921)
It is the test in which PE 100 pipes are examined in abbreviated ambient conditions in order to test their behavior against pressure over time. The changes of Pe 100 pipes over a period of 50 years are observed with this test.
- Homogeneity Test (ISO 13949)
It is done with the aim of examining the homogeneous pigment distribution and possible gaps in the structure of the material. The microtome section taken at a thickness of 10-15 µm is examined under the microscope.
