Piping elbow liners
View Patent ↗Liners useful as piping elbow liners comprising a body liner, a tangential inlet liner, and a tangential outlet liner. The tangential inlet liner and the tangential outlet liner can be removably inserted into a cavity in the body liner. The body liner can comprise two substantially-identical body section liners.
1. A method for making a liner joint of a refractory, corrosion-resistant and/or abrasion-resistant lining, comprising the steps of:
providing a first substantially cylindrical structure of the liner material having an inside surface and an inside diameter;
providing a second substantially cylindrical structure of the liner material having a first end, having an inside diameter smaller than the inside diameter of the first structure, and having an outside diameter;
creating a cavity in the first structure having a diameter equal to or larger than the outside diameter of the second structure by removing a plug from the first structure;
shaping the first end of the second structure to be substantially identical to the shape of the created cavity; and
inserting the shaped first end of the second structure into the created cavity of the first structure.
2. A method according to claim 1 , wherein the shaping step is performed by removing a plug from the second structure.
3. A method for making a liner joint of a refractory, corrosion-resistant and/or abrasion-resistant lining, comprising the steps of:
providing a first substantially cylindrical structure of the liner material having an inside surface and an inside diameter;
providing second and third substantially cylindrical structures of the liner material, each structure having a first end, an inside diameter smaller than the inside diameter of the first structure and an outside diameter;
creating two cavities in the first structure by removing plugs from the first structure, each created cavity having a diameter equal to or larger than the outside diameter of the second structure;
shaping the first ends of the second and third structures to be substantially identical to the shapes of the created cavities; and
inserting each shaped first end into a created cavity.
4. A method according to claim 3 , wherein the shaping step is performed by removing plugs from the second structure.
5. A method for making a liner joint of a refractory, corrosion-resistant and/or abrasion-resistant lining, comprising the steps of:
providing a first substantially cylindrical structure of the liner material having an inside surface and an inside diameter;
providing second and third substantially cylindrical structures of the liner material, each structure having a first end, an inside diameter smaller than the inside diameter of the first structure and an outside diameter;
creating a first cavity in the first structure having a diameter equal to or larger than the outside diameter of the second structure by removing plugs from the first structure;
creating a second cavity in the first structure having a diameter equal to or larger than the outside diameter of the third structure by removing plugs from the first structure;
shaping the first end of the second structure to be substantially identical to the shape of the created first cavity;
shaping the first end of the third structure to be substantially identical to the shape of the created second cavity;
inserting the shaped first end of the second structure into the created first cavity; and
inserting the shaped first end of the third structure into the created second cavity.
6. A method according to claim 5 , wherein the shaping steps are performed by removing plugs from the second structure.
