FIELD: manufacturing technology.
SUBSTANCE: invention relates to a method for producing an anti-erosion coating on an inner or outer wall of a fluid-catalytic cracking unit. Method includes: (i) attaching a plurality of metal anchor elements to said metal wall, with each anchor element being fixed individually in an isolated manner to said metal wall or fixed to a specified metal wall assembled with other identical anchor elements by welding the fastening edge of each anchor element to the metal wall, each of the anchor element contains a mounting edge attached to the metal wall, and the anchor body rigidly connected to the mounting edge having an upper edge, which is located away from the fastening edge and defines a plane, while at least one section of the upper edge, which is not located near the upper edge of another identical anchor element and is not assembled with it, has a limiting protrusion to limit the height of the composite material that should cover the top edge of the anchor element, and the limiting protrusion has a limiting edge located at a predetermined distance from the plane defined by the upper edge of the anchor element, (ii) applying a layer of composite material on the metal wall, thickness of which is chosen in such a way that the composite material covers or is flush with the limiting edge of each anchor element limiting protrusions, and the remaining part of the upper edge of each anchor element is covered with a layer of composite material, thickness of which is at least equal to the specified distance. Fluid-catalytic cracking unit is also disclosed.
EFFECT: it is possible to completely coat the fastened sections at the joints with a layer of composite material for a given layer thickness.
