In order to get the bundle to line up with the shell side gasket, the best tool to use to lift the bundle is?

Using a drift pin is the best choice for lifting the bundle to align it with the shell side gasket due to its design and functionality. A drift pin is a tool specifically used to align holes or components, making it ideal for achieving precise alignment. When working with vessel components like bundles and gaskets, ensuring that everything lines up correctly is critical for sealing and operational integrity. The tapered design of a drift pin allows it to fit into the holes of the alignment features, enabling the technician to accurately position the bundle without exerting excessive force or causing damage.

In contrast, a pipe jack, while capable of lifting, is more suited for elevating heavier components rather than facilitating precise alignment. A flange spreader is designed to create space between flanged joints for installation or removal purposes, but it doesn’t help with alignment specifically. A finger wedge can also assist in small adjustments, but it lacks the precise alignment capability that a drift pin provides, making it less suitable for this task. Therefore, the use of a drift pin stands out as the most effective option for aligning the bundle with the gasket effectively.
