Precise Punched Continuous Slot Wire Wrapped Screen Pipe
The Precise Punched Continuous Slot Wire Wrapped Screen Pipe primarily comprises a perforated base pipe, a stainless steel filtration jacket with meticulously punched slots, and a backup ring. The base pipe adheres to API casing or API tubing standards, featuring numerous drilled holes. Crafted from premium stainless steel, the filtration jacket boasts a high-density array of spatial slots achieved through precision digital punching. This jacket is seamlessly welded onto the perforated base pipe via the backup ring. During application, the formation sand is effectively blocked from entering the filtration jacket, while formation fluid effortlessly flows through the slots, ensuring robust sand control. For enhanced protection, an optional outer protective shroud can be added to the filtration jacket.
Key Benefits:
1. Precision Slot Control.
With slot widths ranging from 0.30 to 1.00mm and a width accuracy of ± 0.05mm, this pipe can accommodate formation sand of various particle sizes, perfectly meeting sand control requirements under the well.
2. Exceptional Corrosion Resistance.
The stainless steel filtration jacket with punched slots exhibits formidable resistance to acid, alkali, and salt, making it highly effective against H2S and CO2. This ensures the slots remain unaffected by corrosion over long-term use.
3. Superior Integral Strength and Anti-Deformation Capabilities.
Supported internally by a base pipe and optionally covered by an outer protective shroud, the filtration jacket remains robust. The base pipe's strength, only 2-3% less than standard casing or tubing, ensures it can endure compression deformation from the stratum. Even in cases of localized deformation, the slot gaps remain stable, confirming the pipe's high reliability for sand control.
