Perforated pipe or perforated casing is designed for creating direct link between the wellbore and the producing formation through punched holes in the casing and the cement sheath that surrounds it. It is usually used as a protect casing or supporting pipe of other well screens, such as pipe-based wire wrapped screen The size and distribution of perforated hoses pose a direct impact on well productivity.

• Available in J55 or N80. J55 and N80 have high strength and less potentiality of deformation.
• Punched hoses are smooth and clear without burrs.
• Easy installation.
• Overall preservative treatment creates a dense protective layer over the surface of the pipe and improves corrosive resistance.
• Six types of punched hoses are available for specific application.
