What is the first step in installing a bolted coupling on a steel pipe?

In the process of installing a bolted coupling on a steel pipe, the first step is to mark the end of the pipe with an approved marker. This marking serves to provide a clear reference point, ensuring that the coupling is correctly positioned for optimal sealing and support. Proper alignment is crucial for the effectiveness of the coupling and helps avoid any misplacement that could lead to installation issues or leaks after the coupling is applied.

Marking the pipe also aids in visual confirmation during the installation process, providing a quick way to ensure that all components align correctly with the intended design specifications. Failing to mark the pipe initially could lead to misalignment during the installation, resulting in potential leaks or structural weaknesses in the piping system.

While checking for debris, centering the clamp, and tightening the bolts are important steps in the overall installation process, they follow the initial action of marking the pipe for accuracy and alignment.
