Abstract: The system and method for installing external corrosion guards of the present disclosure comprises a method of protecting tubing in tubular heat exchangers from external corrosion that includes the installation of protective collars or guards around the tube outer diameter at the tubsheet plate, anti-vibration baffle, and/or pass partition plate levels. The external corrosion guards can be installed using a ridge method, where a ridge sits on a plate level, using a mechanical expansion method, and using a mechanical rolling method.

Abstract: An adjustable level having an angled base with legs extending normal to one another from a common edge and with magnets spaced along and extending fully through each leg; an L-shaped bracket having at least one bubble housing fixed to a leg thereof; a post extending from the base and through a hole in the bracket; a spring on the post and between a head on the post and the bracket to bias the bracket towards the base and to thereby engage ribs on the bracket into grooves on the base; and a retainer for retaining the level to objects, including a flexible cord connected to a return spring and a loop and hook to secure the cord in a pulled out condition surrounding an object.
