Over the coming months Zapp will be integrating the Sandvik portfolio, to provide a smooth transition for customers. During the integration period, the full line of Sandvik wire products will continue to be accessible on this website, or via the Zapp website.

Sandvik's Wraptor ductility testing unit will enable a more accurate prediction of the retirement point of a slickline. This can lead to considerable cost savings through the reduced risk of unplanned production stops and the loss of valuable production equipment.
