Abstract

The invention discloses a stainless steel flange. The stainless steel flange comprises a sealing gasket. The sealing gasket is prepared from, by weight, 90-95 parts of FEPM, 3-6 parts of precipitation method white carbon black, 3-8 parts of an LK-620 aluminum-zirconium coupling agent, 1-3 parts of polyamide wax micro powder, 1-3 parts of SAS-60, 2-4 parts of expanded perlite, 5-8 parts of PCDT , 3-5 parts of beewax, 3-5 parts of polyethylene polyamine, 1-3 parts of LSR1, 5-8 parts of a polycarbonate / poly (butyl glycol terephthalate elastomer) blending alloy, 3-5 parts of epoxidized soybean oil and 5-10 parts of polyphenylene sulfone resins. In this way, the stainless steel flange is simple in structure, high in strength and good in sealing performance.

Description

technical field [0001] The invention relates to the technical field of flanges, in particular to a stainless steel flange. Background technique [0002] Flange is a connection tool, and flange connection refers to a detachable connection in which flanges, gaskets and bolts are connected to each other as a combined sealing structure. Flanges are divided into threaded (screw connection) flanges, welding flanges and clip flanges. Flange connection is widely used in construction industry, urban water supply, boiler pressure vessel, petroleum industry, gas supply, chemical industry, food industry, Fire protection, pharmaceutical industry, power station, water conservancy, HVAC and other industries. The existing flange still needs to be improved. Contents of the invention [0003] The technical problem mainly solved by the invention is to provide a stainless steel flange with simple structure, high strength and good sealing performance. [0004] In order to solve the above t...
