Product Description

Description
Perforated drainage pipe is designed for creating direct link between the well bore 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.



Features of Perforated Drainage Pipes
Higher certainty than casing perforated in a well;

Non-staggered and staggered patterns and different shapes available to suit required custom open area; 

Different sized openings at different depths to improve production;

Arrangement of spacing of perforation to keep the strength for resisting collapse;

Less chance of flattening the pipe or making it oblong.



Standards:API 5CT, API5L, ASTM A312,ASTM A409,etc

Material grades:TP304 TP304L TP316 TP316L TP347 TP347H TP321 TP321H TP310 TP310STP410 TP410S TP403 S31803/S32205 S32750 S32760
