Abstract
The present invention relates to a kind of multilayer slip-on welding flange with holes, it includes flange body（1）, the flange body（1）Cross section is in annular shape, by stainless steel layer（1.1）, carbon steel layer（1.2）And back-up coat（1.3）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.A kind of multilayer slip-on welding flange with holes 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 multilayer slip-on welding flange with holes 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 multilayer being connected firmly slip-on welding flange with holes.
The object of the present invention is achieved like this：A kind of multilayer slip-on welding flange with holes, it includes flange body, and 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, the exit orifice at least two, the endoporus at least two are respectively arranged with the flange body from outside to inside.
The internal diameter of the exit orifice is more than endoporus.
Compared with prior art, the invention has the advantages that：
A kind of multilayer slip-on welding flange with holes 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 multilayer slip-on welding flange with holes 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 multilayer slip-on welding flange with holes 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, carbon steel layer 1.2 and back-up coat 1.3, is respectively arranged with exit orifice 2 and endoporus 3, the exit orifice 2 at least two in the flange body 1 from outside to inside, the endoporus 3 at least two, the internal diameter of the exit orifice 2 is more than endoporus 3.
The flange body 1 is made up of stainless steel, carbon steel or nickel steel.
