Inquiry (采购产品): chemical cleaning Gentlemen' My client has a heat exchanger that is fouled on the tube side with a baked on oil deposit approx 1/8th inch thick . I;m looking for sampples of products to test to determine which one would be effective in removing this scale formation. I'm told that chromic acid, trichloroethane, or trichloethelyne may soften and disolve this coating.Can you supply samples of these products or do you have any other recommendations?
