Built-Up Protection Wells are small diameter general-purpose wells for use in low temperature, low pressure, and low fluid velocity applications. Built-Up Protection Wells are constructed by welding or brazing bushings onto tubing. Built- Up Protection Wells of all stainless steel construction have welded-on bushings. Built-Up Protection Wells with brass bushings have brazed-on bushings.
