The perforated casing tube has round holes uniformly distributed for smooth flow of the liquid. It is actually a supporting pipe for sand control system in drilling oil or water wells. The metals are mostly stainless or mild steel.
Perforated Mild Steel Casing Pipe
The Perforated casing is mainly made of stainless steel or carbon steel. It is used as a connection support to make oil or natural gas easy to flow to the wellbore, and has the characteristics of high strength, resistance to deformation, smooth surface, easy installation and long service life.
The Perforated casing has evenly distributed round holes to make the liquid flow smoothly. It is actually a support pipe for sand control systems used to drill oil or water wells. Most of the metal is stainless steel or low carbon steel.
Working principle: Perforated pipe or perforated pipe is used as connection support. It connects the wellbore and the production formation through perforations on the casing and the cement casing surrounding the casing.
