Wherein being provided with projection on the inwall of interior pipe, when tail gas is through interior pipe, described projection serves honeycomb sound-absorbing effect, it is possible to effectively reduce noise; Meanwhile, described projection can also play certain obstruction adsorption, contributes to the dust granules in tail gas and assembles, will not contaminated air.
Further, above-mentioned a kind of automobile exhaust pipe with antioxidant anticorrosive ability, described body is box-structure, and interior pipe seamless welding, and inside is vacuum chamber. Described body interior is set to vacuum chamber, it is ensured that inner tube outer surface not with atmosphere, oxidation reaction will not be there is under the effect of high temperature, vacuum wall body simultaneously, can also effectively reduce the transmission of heat, people or other animals will not be scalded, and then reach safe effect.
Further, above-mentioned a kind of automobile exhaust pipe with antioxidant anticorrosive ability, the inlet end of described air inlet pipe is provided with adpting flange.
Further, above-mentioned a kind of automobile exhaust pipe with antioxidant anticorrosive ability, described exhaust purifier is ternary catalyzing unit. Ternary catalyzing unit can remove the harmful gass such as CO, HC and the NO in vehicle exhaust effectively, reduces the generation of atmospheric pollution.
Further, above-mentioned a kind of automobile exhaust pipe with antioxidant anticorrosive ability, described anti oxidation layer is mixed by the silicon oxide 10%-30% and binding agent 6%-9% and the solvent 20%-22% thereof being made up of sodium phosphate and waterglass of aluminium oxide 35%-45%, 120-140 nanometer of 60-80 nanometer. Described anti oxidation layer is tightly combined owing to it is intermolecular, viscosity is good, good barrier property can be played, the formula of this coating has good high temperature oxidation resistance simultaneously, ensure that interior pipe has the characteristic of good antioxidant anticorrosive under the impact of long high-temperature tail gas, extend the service life of exhaustor.
Further, above-mentioned a kind of automobile exhaust pipe with antioxidant anticorrosive ability, described air inlet pipe and escape pipe adopt stainless steel processing to prepare, and outer surface scribbles zinc coat. Pipeline is coated with by zinc coat, it is possible to ensure to be not result in corrosion phenomenon under the environment of pipeline long-time high temperature again, simultaneously because with part steam in tail gas, zinc coat ensure that the antiseptic property of exhaustor, effectively extend the service life of exhaustor.
