Hydrostatic testing is one of the most accurate and reliable quality control methods in the piping and fluid transfer industries. The main purpose of this test is to check the resistance of pipes and fittings to internal pressure and ensure that there is no leakage, cracking or unwanted deformation. Companies such as Polymer Pars Company, by performing standard hydrostatic tests, ensure that the final products have a safe and reliable performance under real conditions.
What is hydrostatic testing?
Hydrostatic Testing is a process in which a pipe or fitting is filled with water and then subjected to a specified and controlled pressure. This pressure is usually greater than the actual working pressure to truly measure the strength of the product. If the part can withstand the test pressure without leaking or breaking, it is accepted for the test.
Why is hydrostatic testing important?
1. Ensure system safety
In water, sewage, chemical or low-pressure gas transmission networks, the smallest leak can cause serious damage. Hydrostatic testing helps identify any potential weaknesses before installation.
2. Production quality control
Companies like Polymer Pars Company conduct standard tests to verify the quality of raw materials, thickness uniformity and precision of production operations.
3. Avoid repair costs
Any pipe or fitting that fails the test is removed or modified before entering the project; this means reducing repair costs and preventing unexpected failures in the future.
4. Increase system service life
Parts that successfully pass the pressure test usually have a longer life and are more resistant to environmental stresses.
Steps to perform a hydrostatic test
1. Pipe or fitting preparation
The part is visually inspected for cracks, scratches, or visible defects.
2. Water filling
The pipe or fitting is completely filled with clean, air-free water; the presence of air can distort the test results.
3. Pressure application
A specified pressure, usually 1.5 times the system working pressure, is applied using hydraulic pumps.
4. Pressure holding for a period of time
For a standard period of time (from a few minutes to a few hours depending on the product type), the behavior of the part under pressure is examined.
5. Final evaluation
The following items are checked:
• No leaks
• No deformation
• No pressure drop
• The health of connections and seams
In companies such as Pars Polymer Company, these assessments are carried out with precise measuring devices.
