APPLICATIONS

In highly competitive market sectors where increased productivity through better management of operational cost and efficiencies; and improved safety standards are key, Segnut will deliver a clear return.

Threaded metallic nuts are universal in industrial and commercial applications. Nut removal is required for maintenance, inspection or disassembly. In the resources sector, for example, the maintenance budget can be 30% – 50%+ of the mine site total operating cost and part of this involves the regular unfastening of nuts. With use over time, nut removal can become difficult and even impossible as a result of damage, painted coatings, corrosion, debris etc. Oxy flame cutting is the common method of removal requiring hot work permits which not only increases time but add to risks in fire and injury.

Segnuts have the full structural properties of standard nuts and can be used as a replacement in normal applications. The return on investment comes into play when there is a need for multiple change overs of equipment parts.

MULTIPLE APPLICATIONS

  • Wear plates
  • Conveyor liners
  • Mining equipment
  • Steel structures
  • Any application where there is a need for multiple change overs.

DIVERSE INDUSTRIES

  • Mining
  • Infrastructure
  • Oil & gas
  • Marine
  • Construction.

CASE STUDIES

SMS Mining Services – Caterpillar Dozer trial

Background: SMS Mining Services’ fleet of mining equipment operates in a harsh environment, which requires the regular change out of cutting edges on their dozers. Conventional nut removal methods require the use of a RAD or impact gun whilst seized nuts require oxy-acetylene cutting. This results inblade change outs taking up to 6-8 hours.

Result: Changing the cutting edge blade of a Caterpillar D10T Dozer (39 x1 ¼ Class 12 Segnuts) resulted in a reduction of 6.5 hours to the change-over time, representing an 81% saving. There was no damage to the backing plates, the existing bolts were reused and safety of the maintenance crew was improved. This translated directly to increased plant/equipment utilisation and increased productivity through redirection of labour time.

Using target pricing developed for this application – based on initial manufacturing reviews – and in consultation with the client, a $25,000 annual saving per D10T Dozer was projected. This is a significant saving for such a simple change in practice.

Mill chute liner trial

Background: The changeover of ceramic coated wear plates for a Mill Chute liner was analysed. All nuts (M16 Class 8) had previously been oxy flame cut from the liners. For economic reasons, some liners were reused and had the remaining stub of the studded bolt ground off and a new stud welded to the liner.

Result: Changing to Segnuts resulted in a saving of 58 hrs (64% savings).
