Abstract

The utility model discloses a bimetal composite flat welding flange piece which comprises a flat welding flange piece body (1). A flange sealing face (2) and a thread installation hole (3) are arranged on the flat welding flange piece body (1). The bimetal composite flat welding flange piece is characterized in that a corrosion-resisting alloy layer (4) is arranged on the flange sealing face (2), a plurality of round sealing face carved grooves (5) are formed in an end face of the free end (41) of the corrosion-resisting alloy layer (4), and the flat welding flange piece body (1) is made of carbon steel materials. The bimetal composite flat welding flange piece solves the problem that a traditional pure stainless steel flange piece is used in a large-diameter pipeline connection process so as to increase cost.

Description

The compound welded flange sheet of a kind of bimetal
Technical field
The utility model relates to metal tube complex technique field, is specifically related to the compound welded flange sheet of a kind of bimetal.
Background technique
Development along with the domestic industry manufacturing technology, people adopt bimetal composite steel tube instead of pure stainless steel pipeline more and more on industry and civil building, the purpose of doing like this is to reduce cost significantly satisfying under the prerequisite of using effect, also is in order to promote performance sometimes.Yet, when the Placement of pipeline needs flange to connect, but there is not supporting composite flange sheet on the market, can only choose pure stainless flange plate, for large diameter pipeline, supporting steel flange price is very expensive, has increased manufacture cost.
Summary of the invention
The utility model purpose provides the compound welded flange sheet of a kind of bimetal, and the utility model has solved and adopted traditional pure steel flange sheet, the problem that causes cost to increase in the large diameter pipeline connection procedure.
The utility model is achieved through the following technical solutions:
The compound welded flange sheet of a kind of bimetal, comprise welded flange sheet body (1), welded flange sheet body (1) is provided with flange facing (2) and threaded mounting hole (3), it is characterized in that: described flange facing (2) is provided with corrosion resisting alloy layer (4), corrosion resisting alloy layer (4) free end (41) end face is provided with multiple tracks circular seal face cutting (5), and welded flange sheet body (1) is made by carbon steel material.
The further technological scheme of the utility model is:
Described corrosion resisting alloy layer (4) is spliced to form by a plurality of curved panels (42) ringwise.
The utility model further technological scheme is:
Described resistant alloy layer (4) is made by austenitic stainless steel material or for the super austenitic stainless steel material or for two phase stainless steel material, titanium material, nickel and nickel-bass alloy material;
Described corrosion resisting alloy layer (4) is fixed by argon arc welding or for the welding of soldering and flange facing (2);
Described each independent arcuate panel (42) forms annular corrosion resisting alloy layer (4) by the argon arc welding welding;
Described sealing surface cutting (5) degree of depth is 0.5mm~1.5mm.
The present invention compared with prior art, has obvious advantage, welded flange sheet body adopts cheap carbon steel material, the sealing surface of projection is to touch aggressive medium easily, this part material adopts the corrosion resisting alloy layer to cover, thereby guarantee the working life of flange plate, the ratio that corrosion resistant alloy uses only is equivalent to 5%~10% of pure material, thereby can cut down the manufacturing cost and use cost of flange plate significantly.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises welded flange sheet body 1, welded flange sheet body 1 is provided with flange facing 2 and threaded mounting hole 3, flange facing 2 is provided with corrosion resisting alloy layer 4, corrosion resisting alloy layer 4 free end 41 end faces are provided with multiple tracks circular seal face cutting 5, and welded flange sheet body 1 is made by carbon steel material; Described corrosion resisting alloy layer 4 is spliced to form by a plurality of curved panels 42 ringwise; Described resistant alloy layer 4 is made by austenitic stainless steel material or for the super austenitic stainless steel material or for two phase stainless steel material, titanium material, nickel and nickel-bass alloy material; Described corrosion resisting alloy layer 4 is fixed by argon arc welding or for 2 welding of soldering and flange facing; Described each independent arcuate panel 42 forms annular corrosion resisting alloy layer 4 by the argon arc welding welding; Described sealing surface cutting 5 degree of depth are 0.5mm~1.5mm.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
