A containment system and method for creating a confined space around a portion of a piping circuit, and for maintaining the confined space at a designated pressure with a pressurized blanketing gas. The confined spaced with its controlled environment protects against process upsets or icing when insulation is removed from sections in extreme temperature services. The containment system includes a shroud assembly that is made up of a cover configured into a tubular shape, and end plates on axial ends of the cover that mount onto the piping. Support rings are set within the cover that also mount to the pipe, and which provide radial support for the cover along the span between the end plates. Ports are formed through a sidewall of the cover that provide operations personnel access to the piping. Lines carrying the pressurized blanketing gas connect to inlets formed in the cover sidewall.

A glove box has an enclosure having a glass window top and gloves mounted to the front wall. The enclosure can be tilted to so that one or other, or both, of the work piece and the window can be placed at an angle such as may facilitate processing. The glove box has an environmental control system to both to permit flushing with inert or other desired gases, and to permit heating or cooling. The workstand may have cooling passages as well. Controls are mounted inside the enclosure chamber to permit the operator to change working parameters without removing his or her hands from the gloves. A parameter status display may be located outside the enclosure. The window may be provided with a movable smoked glass filter for use during welding. The workstand may be independently adjustable for angle within the enclosure. The glove box has electrical and cooling service penetrations to permit use of a welding electrode.

An apparatus that may entirely be contained in a glovebox for the removal of at least one contaminant from an inert atmosphere. The apparatus includes a body, a media in the body for the removal of at least one of the contaminants from the inert atmosphere flowing through the media, a fan for causing the inert atmosphere to flow through the media and body, and a motor for driving the fan. The apparatus may be provided in combination with a glovebox. A method of purification of the inert atmosphere using such an apparatus is also provided.
