Advantages of Union Steel Slotted Pipe
1. Our perforated pipe use J55/K55/N80 casing and tubings of API standard, with High overall strength, not so easy to deformation.
2. The edge of the slot is vertical, smooth, without burrs, and the slot is uniformity.
3. The perforated pipe is suitable for sandy well, which the diameter of the sand greater than 0.3mm.
4. The slot can be longitudinal and transverse, the section of the slot can be parallel and trapezoidal types, with a wide open area.
5. Slotted screen pipe has a big inner diameter.
