Steel Chimney & Flare Stacks

Structural steel chimneys and flare stacks require regular inspection and maintenance, particularly where sited within industrial areas and exposed to aggressive corrosive atmospheric conditions.

For freestanding units N.D.T. thickness tests of the platework and inspection of any lining system are advisable. Inspection of guyed units should also include measurement of guy rope tensions along with close examination of rope condition and any lubricants or dressings previously applied.

Careful attention should be paid to any bolted or welded joints within the height of the stack and the integrity of any protective paintwork should be assessed and upgraded if necessary. The requirement for an effective anti-corrosion system is particularly important where the supporting structure is constructed of potentially more vulnerable open lattice steelwork.
