To ensure quality and safety, the 2.0m extra-long LPG natural gas pipeline undergoes rigorous testing before being shipped to customers. Here are some common tests:
1. Pressure Test: This test is conducted to evaluate the ability of the pipeline to withstand the required operating pressure. Connect the pipeline to the pressure source and gradually increase the pressure until the specified working pressure or predetermined test pressure is reached. Monitor the pipes for any leaks, deformations or failures during the test.
2. Leak testing: Since gas pipelines carry flammable materials, testing for potential leaks is critical. The pipe is pressurized to a specific pressure level while submerged in water. Any sign of bubbles indicates a leak and is unacceptable. We perform a thorough inspection to determine and resolve the cause of the leak.
3. Burst test: This test evaluates the burst strength of gas pipes. The pressure on the pipe increases significantly until it reaches a breaking point. Testing is conducted in a controlled environment and the results are carefully observed. If a pipe breaks or fails before it reaches the required pressure level, it is considered a quality problem.
4. Flexibility Test: This test measures the gas pipe’s ability to bend without causing damage or performance issues. Pipes are typically subjected to bending stresses under controlled conditions, simulating different installation scenarios. Visually inspect for cracks, breaks, or any other signs of damage that may affect its functionality.
5. Tensile test: This test is to evaluate the physical strength of the gas pipe. The pipe sample is placed in tension until it breaks. This test measures maximum breaking force and elongation at break, thereby indicating the tensile strength of the pipe.
6. Chemical Resistance Test: This test determines the pipe’s resistance to chemical exposure, such as the gases it carries. Pipelines are exposed to different chemicals typically associated with LPG or natural gas. Observe the sample for any signs of corrosion, degradation, or chemical reactions that could compromise the integrity of the pipe.
7. UV Resistance Testing: Since pipes may be exposed to outdoor conditions, it is important to test their resistance to UV radiation. Pipe samples were exposed to UV light for extended periods of time, simulating outdoor conditions. Observe the sample for any signs of discoloration, degradation, or loss of structural integrity.
8. Comply with standards: Gas pipelines are tested to ensure compliance with relevant industry standards and regulations, such as those set by the International Organization for Standardization (ISO) or specific regional standards for gas pipeline installation. These tests verify that the pipeline meets specific performance and safety requirements.
After passing the above tests, only pipes that meet the qualified standards will be delivered to customers by us. We insist on producing high-quality, high-guaranteed products.
