What should be done with the shipping plugs in STI-P3 tanks prior to testing?

In the context of STI-P3 tanks, it is essential to ensure that shipping plugs are handled correctly prior to any testing procedures. Removing the shipping plugs and replacing them with standard threaded plugs is important because the shipping plugs are not designed for long-term use in a storage system. Standard threaded plugs provide a secure seal that is compatible with the operational conditions of the tank, allowing for accurate testing and preventing any leaks.

The integrity of the tank system is crucial during testing, as any failure to properly secure the tank can lead to environmental hazards or inaccurate test results. Replacing the shipping plugs with fittings specifically designed for the operational requirements of the tank is a standard practice to ensure both safety and compliance with regulatory standards.

Other options may involve actions that do not ensure a secure and reliable seal required during testing. For instance, leaving the shipping plugs in place does not address their temporary nature and can lead to potential issues during testing. Adding sealing tape may provide an immediate solution but doesn't ensure the structural integrity needed during the testing process. Inspecting them for compatibility, while useful, does not provide the necessary action of securing the tank for testing. Thus, removal and replacement with appropriate fittings is the best practice in this scenario.
