MANDRELS RECONDITIONING TECHNOLOGY
a Scientifically developed coating material which is applied by welding on the outside surface of the mandrel. The material hardness replicates that of the original mandrel. The repaired mandrel is thereafter chrome plated using the most advanced technology available on the market.
In order to protect our R&D, the process and the product is covered by one or more patents, or patent applications worldwide.

ADVANTAGE
KEY ADVANTAGES
ADVANTAGE
TRADITIONAL APPROACH TO REPAIRING MANDELS
Mandrel Outside Diameter
Diameter becoming smaller after each reconditioning cycle
Hardness
Is typically slightly reduced after each reconditioning cycle
Mandrel Inventory
As a result of dimensional loss, there is a continuous need to purchase new mandrels
TOLEROX ™
Remains the same after each reconditioning cycle
Stays the same after each reconditioning cycle
Dramatically reduces the need to purchase new mandrels
PROCESS
The complete process is done under one roof only. No process is outsourced; we control every step of the production chain to secure the highest quality.
OUTCOME
The mandrel performance after restoration with ToleroX will depend on the material rolled, the wall thickness of the pipes, rolling conditions, etc. ToleroX reconditioned mandrels match the performance of a newly forged mandrel
