Description
Technical field
The present invention relates to a kind of flange, a kind of downhand welding formula Double-layer 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 downhand welding formula Double-layer flange being connected firmly.
The object of the present invention is achieved like this：It includes flange body, and the flange body cross section is made up of in annular shape stainless steel layer and carbon steel layer, and at least two exit orifice are provided with the flange body, and each exit orifice runs through stainless steel layer and carbon steel layer.
Compared with prior art, the invention has the advantages that：
A kind of downhand welding formula Double-layer flange of the present invention, enhances two connections between equipment or pipe, makes it 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 downhand welding formula Double-layer 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.
Embodiment
Referring to Fig. 1 and Fig. 2, a kind of downhand welding formula Double-layer 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, at least two exit orifice 2 are provided with the flange body 1, each exit orifice 2 runs through stainless steel layer 1.1 and carbon steel layer 1.2.
