  • Apparatus containing multiple sequentially used infrared heating zones for tubular articles
    Patent number: 10107438
    Abstract: An apparatus for heating an elongate tubular article, such as a heat shrinkable sleeve applied around a welded pipe joint during pipeline construction. The apparatus is in the form of a frame which can be disposed around the article, the frame having a heater device having both longitudinally disposed heating zones and radially disposed heating sectors, each of which can be independently controlled. Alternatively, or in combination, the apparatus can have an air circulation system. Also, a method for shrinking a heat shrinkable sleeve comprising use of said apparatus.
    Type: Grant

  • Method for applying or repairing a coating on a substrate by inductive heating
    Patent number: 7012227
    Abstract: A method of applying or repairing a coating on a substrate by inductive heating. A susceptor element is applied on the coating and the element and the substrate are inductively energized to cause the substrate and the coating to be heated. The susceptor element is removed from the heated coating before applying the coating or applying a patch to the coating.
