Exhaust wrap is wrapped completely around the manifold. Although this is cheap and fairly simple, it can lead to premature degradation of the manifold. The goal of performance exhaust headers is mainly to decrease flow resistance (back pressure), and to
Hotter exhaust gases travel faster which may reduce turbo lag and improve exhaust gas scavenging. [1] [3] There has been much debate if heat wrap is better than plasma-sprayed coatings. The far cheaper option in the short term is heat wrap being quick and easy to apply. Heat wraps are more fragile and can absorb oil and water.
For example, such a regulation might limit the concentration of NOx to 55 ppmv in a dry combustion exhaust gas corrected to 3 volume percent O 2. As another example, a regulation might limit the concentration of particulate matter to 0.1 grain per standard cubic foot (i.e., scf) of dry exhaust gas corrected to 12 volume percent CO 2.
This technique is mostly used to produce coatings on structural materials. Such coatings provide protection against high temperatures (for example thermal barrier coatings for exhaust heat management), corrosion, erosion, wear; they can also change the appearance, electrical or tribological properties of the surface, replace worn material, etc ...

A run-around coil installation, serving air handling units on the roof of an office building. A run-around coil is a type of energy recovery heat exchanger most often positioned within the supply and exhaust air streams of an air handling system, or in the exhaust gases of an industrial process, to recover the heat energy.
Wearing his wrap-around sunglasses, he smiled while staring at the snow-covered peaks. Having lunch at a rest stop, Dad ate his sandwich, half of Mom’s and four cookies. He was happy in the ...
