Abstract
A swivel joint includes a first pipe section and a second pipe section. The pipe sections may define a flow path via which fluid passes through the swivel joint. One or more surfaces proximate a junction of the first pipe section and the second pipe section may be selectively coated to resist wear from erosion, corrosion, and or abrasion.
