What must be ensured during the installation of gas piping?

During the installation of gas piping, it is essential that the system is pressure tested. This procedure is critical as it ensures that there are no leaks in the gas piping, which could lead to hazardous situations, including gas leaks that pose safety risks. Pressure testing involves sealing off the gas piping system and applying a specified pressure to check for any drop in pressure over time, indicating a potential leak.

Pressure testing is a standard practice in the industry and is necessary before the gas piping can be put into operation. It plays a crucial role in ensuring the reliability and safety of the gas distribution system, confirming that all joints, fittings, and sections of pipe are intact and secure.

While insulation, painting, and exposure of the piping can be important for various reasons, such as thermal efficiency or exterior protection, they do not directly relate to the immediate safety and functionality of the gas system in the same critical way that pressure testing does. Hence, the focus on pressure testing is paramount for compliance with industry standards and ensuring safe operation.
