Description
Technical field
The present invention relates to a kind of flange, a kind of non-skid band neck type low temperature flat 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 non-skid band neck type low temperature flat flange being connected firmly.
The object of the present invention is achieved like this：A kind of non-skid band neck type low temperature flat 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, 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 inwall of the exit orifice at least two, 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 non-skid band neck type low temperature flat 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.
