Development of a Production Technique for Porous Stainless Steel Tubes.

摘要

The report summarizes work performed in developing a production process for seamless porous stainless steel tubing as used for membrane supports in reverse osmosis systems. A process for compacting stainless steel powder in an annular mild steel shell was developed. A prototype quantity of tubing was fabricated to demonstrate process reproducibility and to provide samples for product characterization and evaluation of corrosion resistance. A manufacturing cost estimate was prepared for large scale production of the product. Seamless porous stainless steel tubing is fabricated by loading stainless steel powder into an annular mild steel shell,compacting the powder using a combination of tube drawing and tube reducing,sintering the compacted composite,and chemically removing the mild steel shell.
