Description
Technical field
The present invention relates to a kind of flange, a kind of reinforced double-layer screwed 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 reinforced double-layer screwed flange being connected firmly.
The object of the present invention is achieved like this：A kind of reinforced double-layer screwed flange, it includes flange body, and the flange body cross section is in annular shape, it is made up of stainless steel layer and carbon steel layer, set fluted close to inner radius in the flange body, exit orifice, the exit orifice at least two are provided with the flange body；At least one reinforcement is provided with the flange body.
Compared with prior art, the invention has the advantages that：
A kind of reinforced double-layer screwed 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.
Brief description of the drawings
Fig. 1 is a kind of structural representation of reinforced double-layer screwed flange of the invention.
Fig. 2 is the longitudinal section of flange body in Fig. 1.
Wherein：
Flange body 1
Stainless steel layer 1.1
Carbon steel layer 1.2
Exit orifice 2
Groove 3
Reinforcement 4.
Embodiment
Referring to Fig. 1 and Fig. 2, a kind of reinforced double-layer screwed flange of the present invention, it includes flange body 1, the cross section of flange body 1 is in annular shape, it is made up of stainless steel layer 1.1 and carbon steel layer 1.2, being set in the flange body 1 close to inner radius in fluted 3, the flange body 1 has exit orifice 2, the exit orifice 2 at least two；At least one reinforcement 4 is provided with the flange body 1.
The flange body 1 is made up of stainless steel, carbon steel or nickel steel.
