Galvanized, Stainless Steel, Carbon Steel, Spiral Welded Filter Pipe For Oil Well OEM

Perforated Metal Tubes can be used for vertical wells, the inclined shaft, horizontal wells and various gases, oil and water wells, can be used individually as sand control tube, and also can be used together with fillings.

Material: stainless steel, carbon steel (galvanized or painting), etc

Perforated seam is welded in straight line; with unique spiral distribution formed by spiral welding and greater filter strength. When squeezed in some parts from external, under outside pressure, the forced part will have reduced or closed gap and ensures the reliability of sand control. Made with sophisticated technology, stainless steel filter glove has openings in the side with reduced direct corrosion to the perforated welded sand pipe. Seam gap in the processing ranges between 20 mm-0.7mm. The uniform opening ensures the processing difference is within the error scope allowed - 0.015 mm, also ensures the accuracy of its filter requirements. Using high precision perforating technology, the effective slotting length is the three to five times of common cut seam tube and two to three times of common perforated seam tubes.
