RE: insulation coating
Hi, there is a whole area of applications for TSA, thermally sprayed aluminium coatings on steam and high temperature piping. Corrosion Under Insulation, it is my understanding that NACE now recognizes TSA as giving the best lifetime coating against CUI.
Flame Spray, benefits of using a flame spray gun:
1) Deposition Efficiency is higher than arc spray, so you can do more coating with less wire
2) Deposition Rate, kg per hour can be close to arc spray considering: using large diameter flame spray wire, spray time per manhour greater than arc, simply because of the heat output of arc spray makes it uncomfortable
3) Small components can be coated with focused nozzle, and broad areas with fan nozzle
4) Buy in or start up cost much, much cheaper than arc spray probably buy 4 flame for price of one arc spray
5) Flame spray is highly mobile
6) Bonding, in some cases it can actually be better than arc.
