Description
Technical field
The present invention relates to a kind of flange, a kind of multi-layer plate-type slip-on welding 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 multi-layer plate-type slip-on welding flange being connected firmly.
The object of the present invention is achieved like this：A kind of multi-layer plate-type slip-on welding 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, exit orifice and endoporus are respectively arranged with from outside to inside in the flange body, the exit orifice at least two, the endoporus at least two, the inwall of each exit orifice and exit orifice 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 multi-layer plate-type slip-on welding 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 multi-layer plate-type slip-on welding 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
Back-up coat 1.3
Exit orifice 2
Endoporus 3.
Embodiment
Referring to Fig. 1 and Fig. 2, a kind of multi-layer plate-type slip-on welding flange of the present invention, it includes flange body 1, the cross section of flange body 1 is made up of stainless steel layer 1.1, carbon steel layer 1.2 and back-up coat 1.3 in annular shape, exit orifice 2 and endoporus 3 is respectively arranged with from outside to inside in the flange body 1, 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, and the inwall of each exit orifice 2 and exit orifice 3 is provided with skid resistant course.
The flange body 1 is made up of stainless steel, carbon steel or nickel steel.
