Date:2020-03-25 keywords:casing, tubing
Tubing naturally has a smaller diameter than
casing pipe, except for the 4 1/2-inch diameter. An outer diameter of 114.3 mm (4 1/2 inches) is considered a threshold and can be either casing or tubing. Anything smaller is called tubing, anything larger is casing.
