Abstract
The present invention relates to a kind of anti-skidding flange of major diameter, it includes flange body（1）, the flange body（1）Cross section is in annular shape, by stainless steel layer（1.1）And carbon steel layer（1.2）Composition；The flange body（1）On be respectively arranged with exit orifice from outside to inside（2）And endoporus（3）, the exit orifice（2）At least two, the endoporus（3）At least two, each exit orifice（2）And endoporus（3）Inwall be provided with skid resistant course.A kind of anti-skidding flange of major diameter 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 anti-skidding flange of major diameter 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 anti-skidding flange of the major diameter being connected firmly.
The object of the present invention is achieved like this：A kind of anti-skidding flange of major diameter, it includes flange body, and the flange body cross section is made up of in annular shape stainless steel layer and carbon steel layer；It is respectively arranged with exit orifice and endoporus in the flange body from outside to inside, the exit orifice at least two, the endoporus at least two, the inwall of each exit orifice and endoporus is provided with skid resistant course.
The internal diameter of the exit orifice is more than endoporus.
Compared with prior art, the invention has the advantages that：
A kind of anti-skidding flange of major diameter 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.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the anti-skidding flange of major diameter of the invention.
Fig. 2 is the longitudinal section of flange body.
Wherein：
Flange body 1
Stainless steel layer 1.1
Carbon steel layer 1.2
Exit orifice 2
Endoporus 3.
Embodiment
Referring to Fig. 1 and Fig. 2, a kind of anti-skidding flange of major diameter of the invention, it includes flange body 1, and the cross section of flange body 1 is made up of in annular shape stainless steel layer 1.1 and carbon steel layer 1.2；It is respectively arranged with exit orifice 2 and endoporus 3 in the flange body 1 from outside to inside, the exit orifice 2 at least two, the endoporus 3 at least two, the internal diameter of the exit orifice 2 is more than endoporus 3, the inwall of each exit orifice 2 and endoporus 3 is provided with skid resistant course.
The flange body 1 is made up of stainless steel, carbon steel or nickel steel.
