Abstract: The quaternary ammonium compound described by general formula 1 below (wherein R1, R2 and R3 are the same or different hydrocarbon radicals with 1 to 4 carbon atoms, and n is an integer between 1 and 10) is used as a metal corrosion inhibitor. With this metal corrosion inhibitor, it is possible even with the addition of small quantities to adequately prevent corrosion of metal in a steam generating unit or petroleum refining or petrochemical process unit. Moreover, (?-hydroxyethyl)trimethylammonium hydroxide is used as a hydrogen chloride formation inhibitor for a crude oil atmospheric distillation unit. With this hydrogen chloride formation inhibitor, it is possible to prevent the formation of hydrogen chloride itself in a crude oil atmospheric distillation unit without having any adverse effect on the catalyst.

Abstract: A composite hose for heavy-duty purposes is disclosed which is essentially comprised of a flexible main hose of increased diameter and a subhose disposed longitudinally thereover. The subhose has a reinforcing layer oriented at a specified angle to thereby dilate widthwise upon application of pressure, allowing the main hose to readily bend in a predetermined direction.
