What are the differences between casing and tubing
What is casing pipe? Casing is a series of steel pipes that are run into a drilled oil well to stabilize the well, keep contaminants and water out of the oil stream, and prevent oil from leaching into the groundwater. Casing is installed in layers, in sections of decreasing diameter that are join...Read more -
ASTM A420 Carbon & Alloy Steel Pipe Fittings
