Problems solved by technology

[0002] Flanges, also known as flange flanges or flanges, are parts that are connected to each other between pipes. They are used for connection between pipe ends, and are also useful for flanges on equipment inlets. The connection between equipment, such as reducer flange, etc., flange connection or flange joint refers to the detachable connection of flange, gasket and bolt as a group of combined sealing structure. Refers to the flange used for piping in the pipelin

Abstract

The invention discloses a high-temperature combined type flange. A protective layer is coated on the surface of the flange and comprises the following components in parts by mass: 10-15 parts of zircon powder, 15-18 parts of diatomite, 20-25 parts of isopropanol, 20-40 parts of polyvinyl acetate emulsion, 30-40 parts of acrylic resin, 10-15 parts of polypropylene carbonate glycol, 10-15 parts of 1,4-butanediol, 8-10 parts of ammonium polyphosphate, 1-3 parts of formaldehyde, 7-15 parts of triphenyl phosphate, 14-20 parts of a modified polyamide curing agent, and 10-15 parts of a silane coupling agent. The flange has relatively high temperature resistance and long service life.

Description

technical field [0001] The invention relates to a flange, in particular to a high-temperature combined flange. Background technique [0002] Flanges, also known as flange flanges or flanges, are parts that are connected to each other between pipes. They are used for connection between pipe ends, and are also useful for flanges on equipment inlets. The connection between equipment, such as reducer flange, etc., flange connection or flange joint refers to the detachable connection of flange, gasket and bolt as a group of combined sealing structure. Refers to the flange used for piping in the pipeline installation. When used on equipment, it refers to the inlet and outlet flanges of the equipment. There are holes on the flange, and the bolts make the two flanges tightly connected. The gasket is used to seal the flanges. The flanges are connected by threads. There are many types of flanges, welding flanges and clamping flanges. At present, the existing flanges do not have the c...
