No header, but the framing still needs to be strong enough to hold the weight of the materials above it.
NO !
A typical load bearing header will be 2 2x12s with a 7/16 plywood spacer between them.
No.
The load bearing header size chart provides information on the recommended sizes of headers needed to support different loads in a building's structure.
The part of the framing above a window opening is known as the lintel. It is a horizontal structural element that supports the load from above, helping distribute the weight of the structure evenly.

To properly install a wall header in a load-bearing wall, you need to first determine the size of the header required based on the span and load it will support. Next, you will need to remove the existing studs where the header will be placed and install the header using appropriate fasteners and support. It is important to follow building codes and consult with a structural engineer if needed to ensure the header is installed correctly and safely.
A non-load bearing door header in a building structure is used to support the weight of the door and its frame, providing stability and ensuring proper alignment of the door within the wall. It helps distribute the weight of the door and any loads above it to the surrounding walls, preventing sagging or damage to the structure.
Outside wall, inside partition wall, usually down the center of the house, header over a door or window, top and bottom plate in the wall, the floor the wall sits on, the rim joist the wall sits on, the floor joists, these are all horizontal load bearing features.
You must temporarily support the framing above on each side of the wall, then emplace an adequately sized header to support the load, and transfer that load appropriately. Contact a qualified carpenter or seek the advice of a structural engineer.
I would install studs, or struts, on each side of the pipe in question.
A partition wall divides a larger space. Non load bearing means that it's not supporting the floor or wall above.
