Description

Trough of belt hub low temperature carbon steel welded flange
Technical field
The present invention relates to a kind of flange, a kind of trough of belt hub low temperature carbon steel welded 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 trough of belt hub low temperature carbon steel welded flange being connected firmly.
The object of the present invention is achieved like this：A kind of trough of belt hub low temperature carbon steel welded flange, it includes flange body, the flange body cross section is in annular shape, inner radius is provided with raised and groove in the flange body, it is described raised in circular, exit orifice and endoporus, the exit orifice at least two are respectively arranged with from outside to inside in the flange body, the inwall of the endoporus at least two, each exit orifice and endoporus 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 trough of belt hub low temperature carbon steel welded 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 trough of belt hub low temperature carbon steel welded flange of the invention.
Wherein：
Flange body 1
Exit orifice 2
Endoporus 3
Projection 4
Groove 5.
Embodiment
Referring to Fig. 1, a kind of trough of belt hub low temperature carbon steel welded flange of the present invention, it includes flange body 1, the cross section of flange body 1 is in annular shape, 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, and the inwall of each exit orifice 2 and endoporus 3 is provided with skid resistant course.
The flange body 1 is made up of stainless steel, carbon steel or nickel steel.
