With the features of high strength and deformation resistance, perforated casing pipe is a good solution for easy flow of oil or gas to wellbore.
Perforated casing pipe, mainly made of stainless or mild steel, is also called perforated casing tube. It is used as connection support to make easy flow of oil or gas to the wellbore and featured by the high strength, deformation resistance, smooth surface, easy installation and long service life. Punched holes are distributed in straight line or staggered forms, and the open area of staggered type pipe is larger than the straight type pipe.
Feature：
- High strength and deformation resistance.
- Smooth surface without burrs.
- Easy installation.
- Durable and long service life.
