HDPE Pipes Testing Procedures
HDPE Pipes – Testing Procedures
1. Appearance & Dimension Measurement Test
- Verification of pipe visual appearance and dimensional accuracy (e.g., diameter, wall thickness) to ensure consistency and compliance with specified standards.
2. Melt Flow Index Test (MFI)
- Measurement of the melt flow rate to determine the viscosity of the polymer melt, which indicates processability and molecular weight of the material.
3. Density Test
- Determination of the pipe’s density to ensure uniformity in material composition and confirm compliance with material specifications.
4. Impact Test
- Evaluation of the pipe’s resistance to sudden impacts and external forces, ensuring that the material can withstand physical stress.
5. Hydrostatic Pressure Test
- Simulation of high-pressure conditions to assess the pipe’s ability to withstand pressure without failure, ensuring safety and durability in water and gas distribution applications.
6. Tensile Strength Test
- Measurement of the material's resistance to pulling forces, ensuring the pipe can withstand mechanical stresses without breaking or deforming.
7. Heat Deflection Temperature Test (HDT
- Determining the temperature at which the pipe material deforms under a specified load, helping to assess the pipe’s suitability for high-temperature environments.
8. Elongation Test
- Measurement of the pipe’s ability to stretch before breaking, indicating its flexibility and ability to handle expansion and contraction under different conditions.
9. Environmental Stress Cracking Resistance (ESCR) Test
- Evaluation of the material’s resistance to cracking under stress, especially in the presence of environmental factors like chemicals or UV exposure, ensuring the pipe’s long-term durability and reliability.
