A cylindrical insert, placed in the form of a concrete wall, in a location where a pipe is to pierce the wall; the insert prevents concrete from flowing into the cylindrical opening.
Pipe sleeves are generally one of three things: a protective ring used to keep a pipe hole open, a ring used to fill the gap between a pipe and another surface, or a covering to create a barrier between a pipe and its surroundings. These sleeves are used during the construction of a building or pipe system.
Pipe Sleeves Baseplate: This includes a base portion that defines a longitudinal axis. The base plate further includes two flanges: a first flange that elongates from the base portion in a first direction mundane to the longitudinal axis and lies in a first plane. The second flange elongates from the base portion in the first direction, generally parallel to the longitudinal axis, and lies in a second plane spaced from the first plane.
Sleeve portion: The sleeve portion of the pipe sleeves consists of a body portion and a third flange that elongates from the body portion in the first direction.
