Abstract
A wear resistant pipe elbow is provided having a seamless inner liner with an upstream beveled end directing fluid flow away from the interior surface of the pipe elbow, thereby protecting the interior surface of the pipe elbow from abrasive particles contained in the fluid, and a downstream beveled end, which assists in directing fluid flow away from the inner surface of downstream pipe sections. The pipe elbow may also include a particle trap cavity, which traps particles suspended in the fluid flow. The trapped particles act as a buffer between a portion of the interior surface of the pipe elbow and particles subsequently carried in the fluid flow, thereby additionally protecting a portion of the interior surface of the pipe elbow from abrasion.
Claims9
A pipe elbow, comprising:
- an outer shell having an upstream end, a downstream end, and an interior surface defining an interior space;
- and
- a seamless liner extending substantially over the interior surface of the outer shell, the seamless liner including an outer and an inner surface and a beveled annular end tapered from the inner surface to the outer surface in a downstream direction, the beveled annular end being generally adjacent the upstream end of the outer shell, the seamless liner further including a half annular lip end generally adjacent to radially outward portion of the downstream end of the outer shell, the half annular lip end slanting generally in the downstream direction and extending a distance into the interior space.
