What should be done with foreign materials found inside a pipe before testing?

When conducting tests on pipes intended for the transport of gases or liquids, it is critical to ensure that the testing environment is uncontaminated and properly prepared. Foreign materials found inside a pipe can interfere with the accuracy of the test results and potentially compromise the integrity of the pipe system. Contaminants can affect the flow of gas or liquid, lead to inaccurate pressure readings, or create safety hazards during testing.

Removing these foreign materials ensures that the pipe is in optimal condition for testing and that the data gathered will reflect the true performance of the system. This practice not only adheres to safety standards but also helps in maintaining the reliability and effectiveness of the gas piping infrastructure. Testing with clean, unobstructed pipes allows for conclusive results that uphold regulatory standards and ensure the safety of the gas delivery system.
