Tubes

We supply tubes in the qualities EN-GJL-250 (GG25), EN-GJS-400-15 (GGG40), EN-GJS-500-7 (GGG50) en EN-GJS-600-3 (GGG60)

Tubes minimum maximum
Outside diameter 50 mm 703 mm
inside diameter 30 mm 597 mm
 

For an indication of the weight of the tube you can calculate: Weight of the outside diameter -/- weight of the inside diameter

  • Standard lengths:
    500 mm en 1000 mm
  • Condition
    Outside diameter as cast or proof machined, inside diameter trepanned
  • Tolerance on inside diameter
    -2 tot -3 mm on the finished sizes

Tubes with a larger diameter can be offered from centrifugal or static casting
