At a steel mill, oscillation occurred during the winding of this hard pipeline steel coil leaving it in a "telescoped" condition. It did not pass quality inspection, and could not be shipped to the customer. Not willing to send valuable materials to the scrap heap without exploring alternatives, the steel mill placed a call to SOS Services, Inc. After assessing the damage, we recognized that the coil was easily repairable, and dispatched a service team with the equipment needed to get the job done.

Working outside in the coil yard to avoid disrupting normal plant operations, we utilized a truck-mounted PM Series 32 knuckle crane to lift our large mobile hydraulic press into position. With 1.2 million lbs. of pressure available, we hydraulically squeezed the coil back to an acceptable condition, with only a 1/8" variance on the side wall. It was then banded with A.A.R. - approved 2" x .044" steel strapping so it would maintain its corrected condition thru transit.

Our skilled team, proprietary equipment and "safety first" approach, enabled us to restore this telescoped coil in much less time and at a fraction of the cost of re-manufacturing it.

  • Product Description
    Galvanized Steel Coil Pancake Flat ! A steel distributor received a galvanized steel coil that needed to be slit in house then shipped to another customer's location. After being unloaded the coil lost it's structural integrity and collapsed. A coating issue allowed the winding tension to buckle inward, deflating the coil eye.
  • Capabilities Applied/Processes
    The flat coil was jacked lifted up and held safely in place, while the tension buckle was hydraulically pressed back into place. Steel sleeves or rings were then inserted into the coil to maintain the correct I.D. size. The sleeves then were hydraulically locked into place correcting the shape of the entire coil.
