WELDLESS TRANSFER TUBE ASSEMBLY

摘要

A weldless assembly comprises a plurality of tubes, wherein the plurality of tubes includes an inner tube, an intermediate tube, and an outer tube; a first closure end configured to cap a first side of the plurality of tubes; and a second closure end configured to cap a second side of the plurality of tubes.

主权项

1. A method of constructing a weldless assembly, comprising:
inserting an inner tube into an intermediate tube; applying a first closure end onto the intermediate tube and the inner tube thereby constructing the first sub-assembly; inserting the first sub-assembly into an outer tube by forcing an end of the first sub-assembly opposite to the first closure end through the center of the outer tube; applying a second closure end onto the end of the first sub-assembly opposite to the first closure end; and applying a guide onto the second closure end thereby constructing the weldless assembly.
