OSTI ID:6177985
This blast joint employs ceramic material to resist the eroding action of the fluid flowing against the joint. The blast joint consists of a ceramic sleeve of the isostatic type made up of several tubular members that are slipped on the tubing joint in end-to-end relationship opposite a producing zone in a well. The sleeve assembly is held in position by annular stop collars of an impact resistant, non-brittle material, such as steel, and are held in position by set screws. The end surfaces of the ceramic tubular members are conically shaped and arranged so the facing surfaces of adjacent members will overlap. An annular protector ring encircles the abutting end surfaces and is made of steel, aluminum, copper or certain plastics that are impact resistant. (9 claims)
