Nanoclad Pipe Weld Repair, Systems and Methods

摘要

An in situ apparatus, system, and method for cladding or repairing cladding in installed pipelines are presented. The apparatus can include a coating collar, a material reservoir, a cladding head, an adjustable cladding chamber, and a chamber controller. The coating collar can include an external surface, a first circumferential wall, and a second circumferential wall and forms the adjustable cladding chamber along with interior wall of the pipe. The coating collar can have an aperture to include and allow deployment of the cladding head through it. The cladding head can be operatively coupled with the cladding material reservoir to allow efficient deployment of the cladding material on the pipe surface. The chamber controller can be coupled with the adjustable cladding chamber to control dimensions of the chamber thus restricting and controlling the environment and enabling efficient functioning of the cladding head and limiting grain growth in applied nanoclad materials.

主权项

1. An in situ cladding apparatus for cladding within an installed pipe, the apparatus comprising:
a coating collar around a portion of a main body of the apparatus, the collar configured to allow deployment of a cladding head through the collar; at least one cladding material reservoir capable of storing a cladding material coupled to the cladding head; an adjustable cladding chamber formed from an interior wall of the pipe, an external surface of the coating collar, at least a first circumferential wall and a second circumferential wall extending away from the coating collar toward the interior wall; a chamber controller configured to control dimensions of the adjustable chamber by controlling a position of at least one of the external surface of the coating collar, the first circumferential wall, and the second circumferential wall relative to the interior wall of the pipe; and wherein under control of the chamber controller the adjustable cladding chamber substantially forms a restricted cladding environment accessible to the cladding head.
