Induction hardening of pipes and bends:
the inner surface is hardened to a level which withstands abrasion while keeping the outer surface ductile to accomodate normal installation and maintenance.
Ultra 600 precision controlled heating-quenching process to change the micro-structure of the inner pipe wall to increase hardness and abrasion-resistance.
- inner surface hardness: HB 600
- outer surface hardness: ductile at HB 250
- diameters: 53 – 1016 mm
- pipe lengths: 15,24 m
