The primary tests conducted during a gas pipe installation are crucial for ensuring the safety and reliability of the gas system. A leak test and pressure test are both vital to confirm that the gas pipes are properly sealed and can withstand the pressures they will face during operation.

The leak test involves pressurizing the gas piping system with a specific medium, commonly air or an inert gas, and monitoring for any pressure drops over a set period. This helps identify any potential leaks in the system that could pose safety hazards.

The pressure test ensures that the system can safely handle the operating pressures expected once the gas is introduced. This test not only verifies the integrity of the installation but also prepares the system for actual operation.

In contrast, other options listed involve testing methods that are not standard for verifying gas pipe installations. Routine inspections and diagnostic techniques like thermal imaging or flow rate tests may be useful in different contexts but do not fundamentally serve the purpose of confirming the integrity and safety of gas pipe installations right after they are installed. Similarly, resistance and calibration tests are more relevant to electrical systems rather than gas piping assessments.
