Abstract
The exposure of components to high-pressure fluids can result in the application of high tensile stresses to those components, which may lead to reduced life. The preload system described herein helps to reduce the magnitude of those tensile stresses by providing a body and a plug. The body includes a first bore and a second bore. The first bore is configured to be exposed to high tensile stresses. The second bore includes a first engagement structure and a bottom surface near a first portion of the first bore. The plug includes a second engagement structure and a first end. The second engagement structure engages the first engagement structure to force the first end of the plug against the bottom surface of the bore. The force of the plug against the bottom surface of the bore applies a compressive preload to the first portion of the first bore.
