Abstract
The utility model relates to a kind of stainless steel pipeline blind flange plugging structure, comprise steel pipe and the blind flange for shutoff steel pipe, steel pipe is socketed with moveable flange plate, flange plate adopts plain carbon steel material, the connecting end of described steel pipe is welded with Stainless Steel Disc, and the side end face of described Stainless Steel Disc contacts with the side end face of flange plate; Described flange plate and blind flange are provided with some bolts hole, and multiple bolt is each passed through a bolt hole and flange plate and blind flange is connected and fixed.Reduce the cost of steel pipe through flange shutoff, improve the sealing of steel tube end part plugging structure.
Description
Technical field
The utility model relates to a kind of stainless steel pipeline blind flange plugging structure.
Background technique
Plain carbon steel is carbon steel, that is: be iron carbon alloy.According to the height of carbon content, be divided into low-carbon (LC) steel checkerboard (being commonly called as: wrought iron), middle-carbon steel and cast iron.General carbon content be less than 0.2% be low carbon steel, be commonly called as wrought iron or pure iron; Content is steel at 0.2-1.7%; Content is the pig iron more than 1.7%.
Stainless steel: chromium content is greater than more than 12.5% in steel, has the steel that the extraneous medium (acid, alkali, salt) of higher opposing is corroded.According to the organization factors in steel, stainless steel can be divided into martensite type, ferrite type, Austenitic, ferrite-Austenitic.
On market, stainless price will far above the price of plain carbon steel, the flange being conventionally used to fastener for connection is all the stainless steel adopted, if adopt the flange of other materials to be unfavorable for and fastener for connection, because material is different, because conventional flange is all the stainless steel adopted, therefore cost can be in any more.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of stainless steel pipeline blind flange plugging structure.
The utility model solves the technological scheme that its technical problem adopts: a kind of stainless steel pipeline blind flange plugging structure, comprise steel pipe and the blind flange for shutoff steel pipe, steel pipe is socketed with moveable flange plate, described flange plate adopts plain carbon steel material, the connecting end of described steel pipe is welded with Stainless Steel Disc, and the side end face of described Stainless Steel Disc contacts with the side end face of flange plate; Described flange plate and blind flange are provided with some bolts hole, and multiple bolt is each passed through a bolt hole and flange plate and blind flange is connected and fixed.
Further, between Stainless Steel Disc and blind flange, gasket seal is provided with.
The beneficial effects of the utility model are: reduce the cost of steel pipe through flange shutoff, improve the sealing of steel tube end part plugging structure.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Wherein: 1, steel pipe, 2, flange plate, 3, Stainless Steel Disc, 4, blind flange, 5, gasket seal.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of stainless steel pipeline blind flange plugging structure, comprise steel pipe 1 and the blind flange 4 for shutoff steel pipe 1, steel pipe 1 is socketed with moveable flange plate 2, flange plate 2 adopts plain carbon steel material, the connecting end of steel pipe 1 is welded with Stainless Steel Disc 3, and the side end face of Stainless Steel Disc 3 contacts with the side end face of flange plate 2; Described flange plate 2 and blind flange 4 are provided with some bolts hole, and multiple bolt is each passed through a bolt hole and flange plate 2 and blind flange 4 is connected and fixed.For improving the sealing connected between rust steel disk 3 and blind flange 4, between Stainless Steel Disc 3 and blind flange 4, be provided with gasket seal 5.
Single for tradition steel flange is become present Stainless Steel Disc 3 and flange plate 2, and Stainless Steel Disc 3 is mainly used in welding with steel pipe 1, and carries out sealing with blind flange 4 and contact and coordinate, and therefore Stainless Steel Disc 3 still adopts stainless steel; And flange plate 2 is actively socketed on steel pipe 1, undertaken spacing by the Stainless Steel Disc 3 being welded on steel pipe 1 end, thus through bolt, steel pipe 1 and blind flange 4 are linked together, because flange plate 2 does not weld with steel pipe 1 at needs, it is mainly used in being connected and fixed with blind flange 4, and therefore its material can be changed, and the plain carbon steel that price can be adopted lower replaces, reduce the cost of steel pipe 1 shutoff, also improve the sealing of steel pipe 1 shutoff simultaneously.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
