Description
Technical field
The present invention relates to a kind of flange, a kind of anti-skidding double-deck downhand welding formula 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 anti-skidding double-deck downhand welding formula flange being connected firmly.
The object of the present invention is achieved like this：A kind of anti-skidding double-deck downhand welding formula flange, it includes flange body, the flange body cross section is in annular shape, it is made up of stainless steel layer and carbon steel layer, at least two exit orifice are provided with the flange body, the inwall of each exit orifice is provided with skid resistant course, 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 anti-skidding double-deck downhand welding formula flange of the 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 anti-skidding double-deck downhand welding formula flange of the present invention.
Fig. 2 is the longitudinal section of flange body in Fig. 1.
Wherein：
Flange body 1
