Description
Technical field
The present invention relates to a kind of flange, it is specifically related to a kind of double-deck hub reinforcement type and accepts welding method orchid.
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 double-deck hub reinforcement type undertaking welding method being connected firmly is blue.
The object of the present invention is achieved like this：It is blue that a kind of double-deck hub reinforcement type accepts welding method, 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, inner radius is provided with raised and groove in the flange body, it is described raised in annular shape, 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 endoporus is provided with skid resistant course, the flange body and is provided with least one reinforcement.
The internal diameter of the exit orifice is more than endoporus.
Compared with prior art, the invention has the advantages that：
It is blue that a kind of double-deck hub reinforcement type of the present invention accepts welding method 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 accepts the blue structural representation of welding method for a kind of double-deck hub reinforcement type of the present 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
Endoporus 3
Projection 4
Groove 5
Reinforcement 6.
Embodiment
Referring to Fig. 1 and Fig. 2, it is blue that a kind of double-deck hub reinforcement type of the present invention accepts welding method, 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, inner radius is provided with projection 4 and groove 5 in the flange body 1, described raised 4 in annular shape, exit orifice 2 and endoporus 3 are 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, the inwall of each exit orifice 2 and endoporus 3 is provided with skid resistant course, at least one reinforcement 6 is provided with the flange body 1.
The flange body 1 is made up of stainless steel, carbon steel or nickel steel.
