Problems solved by technology

[0003] In the production process of isooctane, the raw material feed pipe needs to be in contact with chemical substances for a long time, so the limitation of the application environment requires the alloy feed pipe to have excellent oxidation resistance and corrosion resistance. The corrosion resistance of the alloy feed pipe cannot meet our needs

Abstract

The invention discloses a corrosion-resistant alloy feed pipe for isooctane production and a processing technology thereof. Since the feed pipe disclosed in the present application is used for isooctane production, the feed pipe involved in the production process has long been incompatible with chemical substances. Therefore, the limitation of the application environment requires that the alloy feed pipe needs to have relatively excellent anti-oxidation and corrosion resistance; therefore, the application uses 316L stainless steel to prepare the alloy pipe body, and perform surface treatment on it to improve its surface resistance. Corrosive properties. In this application, aluminum powder is used as the aluminum supply agent, silicon powder is used as the silicon supply agent, and calcium chloride is used as the activator. After the co-infiltration slurry is prepared according to the formula, the aluminum-silicon co-infiltration layer is co-infiltrated on the surface of the alloy pipe body; the setting of the aluminum-silicon co-infiltration layer It can effectively improve the corrosion resistance of the alloy feed pipe; the process design is reasonable, the operation is simple, the prepared alloy feed pipe has excellent corrosion resistance, and the surface is hydrophobic, which can effectively block the entry of corrosive media and improve the use of the feed pipe longevity and high practicability.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a corrosion-resistant alloy feed pipe for isooctane production and a processing technology thereof. Background technique [0002] Alkylation reaction refers to the reaction of introducing an alkyl group (-R) into carbon, nitrogen, oxygen and other atoms in organic molecules, which is referred to as alkylation. Commonly used alkylating agents include alkenes, halogenated alkanes, alkyl sulfates and alcohols, etc. The alkylated products mainly include alkanes and their derivatives, aromatic hydrocarbons and their derivatives. Alkanes and their derivatives include fatty alcohols, fatty amines, carboxylic acids and their derivatives, etc. Through alkylation, methyl, ethyl, isopropyl, tert-butyl, and long carbon chains can be introduced into the alkylated molecule. Alkyl and other alkyl groups. [0003] In the production process of isooctane, the raw material feed pipe needs to be in...
