Perforated Support Core / Back Up Tube

Perforated Support Core or Perforated Back-Up Tube is the main internal component within the strainer housing. The Strainer Assembly can be used with the Back-Up Tube by itself for coarse separation, or with a Wire Mesh OverScreen for straining (down to 74 microns), or with a Filter Sock for filtering down to 25 microns. The Perforated Back-Up Tube is punched from 316L SS sheet. The Back-Up tube has solid edge margins at both ends of the tube, and on either side of the longitudinal welded seam. All welds are gound smooth. The Back-Up Tube is electro-polished ensuring a surface finish of 25Ra or better.
