I don't do stacks or chimneys, but I have seen this term strates used before in SEAINT. What so these things look like? I didn't find much useful information on Google other than they breakup the airflow.

Fellow engineers, I have a client who manufactures flare systems for the oil and gas industry. A major component of these systems is the flare stack itself.These stacks vary from 40' to 80' tall with the top 6' to 10' varying from 4" to 8" stainless steel pipe with a burner tip at the top.Occasionally, vortex shedding may be a concern; my client iswilling to go to almost any length to avoid the use of traditional strakes. My question "What do you think of the idea of creating strakes by wrapping the top third of the stack with wire rope and securing the rope to the stack with clips that are tack welded to the stack?" The cost of wire rope strakes would seem to be only a small fraction of the cost oftraditional rolled plate strakes. Regards, H. Daryl Richardson
