Abstract
Apparatus and method contemplating a high pressure fluid end assembly having a body defining a body bore and defining a recess in the body intersecting the body bore. A closure is joined to the body and forms a sealing surface. A seal is mounted to the body in the recess and configured to extend from the recess beyond the body bore to seal against the sealing surface formed by the closure.
Claims25
A method for manufacturing a fluid end assembly comprising:
- providing a housing having an external surface, an internal chamber, a first conduit formed in the housing having first and second sections, and a second conduit formed in the housing, intersecting the first conduit and having third and fourth sections, each section independently interconnecting the internal chamber and the external surface;
- forming an endless groove in the housing such that the groove surrounds the first section;
- positioning a seal within the groove;
- installing a discharge plug within the first section such that at least a portion of the discharge plug engages with the seal so as to form a barrier to fluid flow, in which the discharge plug has a top surface and an opposed bottom surface;
- and
- positioning a retainer attached to the housing and above the discharge plug such that the retainer is engaged with the top surface of the discharge plug and secures the discharge plug in a stationary position within the first section.
