Wall thickness 8–20 mm depending on section. Materials: Cu-DHP (TP2), CuAg (0.08–0.12 % Ag), CuCrZr. Inner plating: hard chrome 0.08–0.12 mm or nickel-chrome. Sections not listed are also accepted. Download or print this page for your maintenance file.

What You Get With Every Tube

Taper & radius inspection

Every tube is measured on a CMM against the drawing; the report ships with the tube.

Chrome plated bore

Hard chrome 0.08–0.12 mm, uniform along the full length, polished to reduce friction and sticker breakouts.

Material choice

Cu-DHP for standard speed, CuAg for high speed, CuCrZr for long campaigns. We advise on the grade.

Repair & re-plating

Used tubes with worn plating can be re-machined and re-plated instead of replaced.

Made According to Your Drawing

Send the tube drawing, the caster manufacturer's mould specification or a photo of the marking on your old tube (for example "150×150×900 R6000"). We confirm taper, wall thickness, water slot and plating before quoting.

  • PDF, DWG, STEP or a photo with measurements
  • Any radius from R3000 to R15000
  • Square, rectangular, round and H-type sections
  • Matching water jacket and flanges on request
