A casing pipe is a hollow steel tube that is typically rammed into place through the earth by using a hydraulic or pneumatic jack. After being driven, the displaced soil is removed and the product pipe, or carrier pipe, is inserted inside the steel tube.
Casing pipe may also be simply referred to as casing or encasement pipe.
A casing pipe is rarely the product pipe, and is simply used in order to create a bore. This type of pipe is most commonly used to protect utility lines over short distances. The casing pipe may be installed in sections and then welded or threaded together immediately prior to installation.
The diameter of a casing pipe is usually between 4 to 55 inches in diameter, although there have been successful installations of casing pipes as big as 150 inches in diameter.
