Abstract
The present invention relates to a kind of high-neck type alloy steel flange, it includes flange body（1）, the flange body（1）Cross section is in annular shape, by stainless steel layer（1.1）, carbon steel layer（1.2）And back-up coat（1.3）Composition, the flange body（1）It is upper that inner radius is provided with projection（2）, the projection（2）In annular shape, the flange body（1）On be provided with exit orifice（3）, the exit orifice（3）At least two.A kind of high-neck type alloy steel flange of the present invention so that two connections between equipment or pipe are more firm, reduce equipment or the repair rate of pipe, extend its service life.
Description
Technical field
The present invention relates to a kind of flange, a kind of high-neck type alloy steel flange is specifically related to.
Background technology
Flange, is called flange flange disk or bead.Flange is the part being connected with each other between pipe and pipe, for the connection between pipe end；Also have with the flange imported and exported in equipment, for the connection between two equipment, such as reductor flange.Traditional flange is made up of flange body and collar aperture eye, is connected between equipment not enough firmly, the time, long rear bolt easily came off.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency, there is provided a kind of high-neck type alloy steel flange being connected firmly.
The object of the present invention is achieved like this：A kind of high-neck type alloy steel flange, it includes flange body, the flange body cross section is in annular shape, it is made up of stainless steel layer, carbon steel layer and back-up coat, inner radius is provided with projection in the flange body, it is described raised in circular, it is provided with exit orifice, the exit orifice at least two in the flange body.
Compared with prior art, the invention has the advantages that：
A kind of high-neck type alloy steel flange of the present invention so that two connections between equipment or pipe are more firm, reduce equipment or the repair rate of pipe, extend its service life.
