Abstract
A wellhead housing of a wellhead assembly can include a body having a top end, a bottom end, and a cavity that traverses its length between the top end and the bottom end. The wellhead housing can also include a main channel that traverses the body from the cavity at a distal end of the main channel to an outer perimeter of the body at a proximal end of the main channel, where the proximal end of the main channel is located closer to the top end of the body compared to the distal end of the main channel, and where the distal end of the main channel is located closer to the bottom end of the body compared to the proximal end of the main channel.
