Tubos de Acero Inoxidable Sin Costura ASME SA312 ASTM A312 TP304L TP316L PICKLED AND ANNEALED

Yuhong Special Steel 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

Chemical Composition:

 Mechanical Property:

Application :

Widely used for liquid or gas pressure transfer in water treatment, waste water treatment, petrochemical, chemical, pharmaceutical and other industries. And structural applications include handrails, poles and support pipe for salt water and corrosive environments. Compared with type 304 stainless steel, type 316 stainless steel pipe has lower weldability, therefore it is not used as often as welded pipe unless its superior corrosion resistance exceeds weldability.
