The invention relates to a skidproof plate-type flange with three layers of neck-shaped alloys. The skidproof plate-type flange comprises a flange body (1), wherein the cross section of the flange body (1) is annular, and the flange body consists of a stainless steel layer (1.1), a carbon steel layer (1.2) and a reinforcing layer (1.3); a protrusion (2) is arranged at a position close to the inner diameter of the flange body (1), and is annular; a skidproof layer is arranged outside the protrusion (2); and at least two outer holes (3) are formed in the flange body (1). Through the adoption of the skidproof plate-type flange with three layers of neck-shaped alloys disclosed by the invention, the connection between two pieces of equipment or two pipes is firmer, the returning rate of the equipment or the pipes is reduced, and the service life of the equipment or the pipes is prolonged.
Description
Technical field [0001] The invention relates to a flange, in particular to a three-layer alloy plate flange with a non-slip neck type. Background technique [0002] Flange, also called flange flange or flange. Flange is the connecting part between the pipe and the pipe, used for the connection between the pipe ends; it is also useful for the flange on the inlet and outlet of the equipment, used for the connection between two equipment, such as the reducer flange. The traditional flange is composed of the flange body and a circle of holes, the connection between the equipment is not strong enough, and the bolts are easy to fall off after a long time. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a three-layer alloy plate flange with a non-slip neck type with firm connection. [0004] The object of the present invention is achieved as follows: a non-slip necked three-layer alloy plate flange, which ...
