Problems solved by technology

[0003] Since the flange is exposed outside and is used to connect pipes, it is often in a humid and dark environment. In order to improve the life of the flange, its protection measures are particularly important. The existing flange protection measures are as follows. The disadvantage of spraying paint on the blue surface is that it is easy to wear during handling, and the worn part cannot be protected, or it is made of stainless steel, which has high cost and does not have good wear resistance.

Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing.

[0013] Such as figure 1 As shown, an anti-corrosion and durable flange of the present invention includes a flange body 3, a nozzle 6 and a bolt hole 2, a nozzle 6 is arranged in the center of the flange body 3, and a plurality of bolt holes are arranged on the flange body 3 2. The bolt holes 2 are located on the outer periphery of the nozzle 6, and also include a protective layer 1, which is glued on the outer surface of the flange body 6.

[0014] As a further improvement of the present invention, the material of the protective layer 1 is polytetrafluoroethylene. The protective layer 1 can be made of various plastics or other anti-corrosion materials, preferably polytetrafluoroethylene is waterproof, has good anti-corrosion performance and high wear resistance.

[0015] As a further improvement of the present invention, a sealing groove 5 is formed on the inner end surf...

Abstract

The invention discloses an anti-corrosion durable flange plate which comprises a flange body (3), an adapter hole (6), bolt holes (2) and a protecting layer (1), wherein the adapter hole (6) is formed in the center of the flange body (3); a plurality of bolt holes (2) are distributed in the flange body (3) and at the periphery of the adapter hole (6); and the protecting layer (1) is adhered to the outer surface of the flange body (3). The protecting layer is added to the outer surface of the flange body, so that the corrosion resistance and the wear resistance of the flange plate are effectively improved, the flange plate can be better used in a severe environment, and the service life of the flange plate is prolonged.

Description

technical field [0001] The invention relates to a flange, in particular to an anti-corrosion and durable flange. Background technique [0002] The flange is the flange plate. The flange is a part that connects the pipe to the pipe. It is connected to the pipe end and is also useful for the flange on the inlet and outlet of the equipment. . There is a nozzle on the flange, which is used to connect the pipeline. There are a number of bolt holes arranged on the flange. The two flanges are tightly connected by bolts, and the gaskets can be used to seal the flanges. [0003] Since the flange is exposed outside and is used to connect pipes, it is often in a humid and dark environment. In order to improve the life of the flange, its protection measures are particularly important. The existing flange protection measures are as follows. The disadvantage of blue surface spray painting is that it is easy to wear during transportation, and the worn part cannot be protected, or the sta...
