Which action is performed after marking the end of the pipe during bolted coupling installation?

After marking the end of the pipe during the installation of a bolted coupling, the next crucial step is to stab the coupling to the mark. This action ensures that the coupling is positioned correctly on the pipe to guarantee a proper fit and secure connection.

By stabbing the coupling to the mark, the installer aligns the coupling with the designated point on the pipe, which is essential for achieving the required axial alignment and ensuring that the pipe ends are properly engaged within the coupling. Proper placement not only facilitates a good seal but also helps to avoid any misalignment that could lead to leaks or structural failure.

The other actions may also be important in the broader context of the installation process, but they typically occur at different stages. Cleaning the steel surface is important before installation to ensure a good bond but would come before marking. Applying a coating often occurs after ensuring the correct alignment and securing the coupling to provide corrosion resistance. Inspecting the joint according to manufacturer instructions is a critical quality assurance step, typically done after the installation to confirm that everything has been properly executed.
