Abstract

The invention discloses a high-strength crossover flange and a processing technology thereof, and particularly relates to the technical field of flange processing. The high-strength crossover flange comprises acrylamide, vinyl imidazole, ammonium persulfate, graphene oxide, silver nitrate, glucose, nano silicon dioxide, nano yttrium oxide and deionized water in a steel material and a coating material. According to the high-strength crossover flange, the wear resistance, the antibacterial performance and the sealing performance of the high-strength crossover flange can be effectively improved, liquid absorption expansion can be effectively performed after leakage, sealing and locking treatment can be performed again, the leakage problem can be conveniently found in time, continuous use of the crossover flange with the leakage threat can be effectively avoided, and larger loss is avoided; and nano silver particles, a compound of conductive graphene and graphene oxide, nano silicon dioxide and nano yttrium oxide are spliced and compounded into hydrogel, the coating material of a fibrous structure is formed through electrostatic spinning, all components of the coating material can be effectively and rapidly compounded and combined, and the comprehensive performance of the coating material is guaranteed.

Description

technical field [0001] The invention relates to the technical field of flange processing, and more specifically, the invention relates to a high-strength conversion flange and its processing technology. Background technique [0002] Flanges are also called flange flanges or flanges. Flanges are parts that are connected to each other between shafts and are used for connection between different pipe ends. At the same time, there are also flanges used for the inlet and outlet of equipment. A connection between two devices. Flange connection or flange joint refers back to the detachable connection of flange, Gasket and bolt as the combined sealing structure. A flange that converts one connection method (or specification, size) into another connection method is called a conversion flange. [0003] The existing high-strength conversion flange, when the conveying material changes the transmission direction or flow rate, the impact on the conversion flange becomes larger instantly...
