TOBO STEEL Group ASTM GB JIS Large Diameter Stainless Steel Seamless Pipe 406mm- 1524mm OD

ASTM,GB,JIS S3048 Outer Diameter:406mm- 1524mm Stainless Steel Seamless Pipe

TOBO GROUP has developed together with the relevant scientific research organizations series filter products for petroleum chemical filtration: Oil sand control screen (anti-sand filter blocks), spiral welded stainless steel filter tube (spiral welded pipe), straight seam welded stainless steel filter tubes, well received by the oil field customers. Product performance and features: Spiral Welded Pipe 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. Excellent anti-corrosion properties
Center tube is API standard tube or oil tube and the high precision perforated filter glove is made of 304 stainless steel materials.
For wells containing H2S, CO2, high-C l that has special requirements, the center tube can be corrosion-resistant casing or tubing. Screen is acid and alkali resistant and salt corrosion resistant.
