Asset or Write-off: Passivating and Lubricating Steel Wire Ropes
Passivating and lubricating steel wire rope can prolongue the service time of steel wire ropes significantly. As usual, not all steel wire ropes apply. Ropes that face kinking, crushing or continuous welding during their duty have to face the truth that their lives will be short-lived.
Tensioning-ropes, umbilicals, towing-cables, anchoring-cables, elevator cables and safety steel wire ropes are in that group. Still, they do benefit from a decent treatment before construction and stranding. Also after construction or in duty, steel wire ropes apply for a next season of summer.
Passivating and lubricating steel wire rope
Nano corrosion passivation is a water-displacing / corrosion-inhibiting technique. It forms a chemical bond to metal alloys with deep penetrating characteristics. This new technology is the culmination of 30 years experience and development in the field of corrosion control and lubrication. Deployment of Archoil AR5600 provides stable and particularly long-term protection. This is especially suitable for steel wire ropes in extreme corrosive or washing environments.
Pictures tell the story best, here we go:
Treatment of a steel wire rope with Archoil AR5600. Pictures show the dissection of the steel wire rope subject to accelerated corrosion test STD 423-0014. This method has accreditation according to ISO/IEC 17025. Treating a cable after it is completely user ready is common, so the thorough penetration of a traditional fluid to the core is hard to achieve. As AR5600 is a nano-formulation fluid (for corrosion passivation and lubrication), we can see that nanotechnology has it’s benefits in hard-to-enter areas.
Also galvanic corrosion is to be postponed for a longer period of time. Pictures show the same steel wire rope subject to accelerated corrosion test STD 423-0014. Pics show result after a period of time equivalent to 12 months. This is an accredited method according to ISO/IEC 17025.
From write-off to asset: This 2500 meters of steel wire rope served 2 years longer by means of reconditioning. Cost: less than € 3000, investment of € 79000 postponed by 24 months.
