Abstract
The utility model discloses a flange connecting structure for an anti-corrosive pipeline. The flange connecting structure comprises metal flange pipes, wherein anti-corrosive liners are arranged on the inner surfaces of the metal flange pipes; anti-corrosive outer layers are arranged on the outer surfaces of the metal flange pipes. The flange connecting structure is characterized in that the flange-covered parts of the anti-corrosive liner and the anti-corrosive outer layer are provided with right-angled flangings at the right-angled positions, and the flange-covered parts of the anti-corrosive liners and the anti-corrosive outer layers are connected with straight pipe parts by using sealing adhesive at the line sections, so that better sealing effect is easily obtained. The flange connecting structure disclosed by the utility model has the characteristic that the connecting effect of an inner anti-corrosive layer and an outer anti-corrosive layer is good.
Description
Technical field
The flange that the utility model relates to anti-corrosion pipeline connects, specifically a kind of flanged connecting structure for anti-corrosion pipeline.
background technique
Existing anti-corrosion pipe often adopts flange to connect, in order to meet anticorrosion and requirement of strength, the normal metal flange pipe that adopts, then the inner and outer surface at metal flange pipe is coated the good plastic cement liner of antiseptic property and external coating, the disconnected place link position of the plastic cement liner of prior art and external coating is in joint, right angle, and sealing is relatively difficult to process.
Summary of the invention
The purpose of this utility model is the defect for prior art, proposes a kind of flanged connecting structure for anti-corrosion pipeline that can process preferably anticorrosive coat sealing.
The purpose of this utility model is achieved in that a kind of flanged connecting structure for anti-corrosion pipeline of the present utility model, it comprises metal flange pipe, at metal flange pipe internal surface, be provided with corrosion-proof lining, at metal flange tube outer surface, be provided with asepticised outer layer, it is characterized in that above-mentioned corrosion-proof lining and asepticised outer layer have a right angle flanging at the flange covered section of metal flange pipe at place, right angle, the flange covered section of corrosion-proof lining and asepticised outer layer is connected with sealer at straightway with straight-tube portion.
A kind of flanged connecting structure for anti-corrosion pipeline of the present utility model, because corrosion-proof lining and asepticised outer layer have a right angle flanging at the flange covered section of metal flange pipe at place, right angle, therefore the flange covered section of corrosion-proof lining and asepticised outer layer is connected with sealer at straightway with straight-tube portion, easily obtains good sealing effect.The utlity model has the feature of inside and outside anticorrosive coat good connecting effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the flanged connecting structure for anti-corrosion pipeline of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail:
As shown in Figure 1, a kind of flanged connecting structure for anti-corrosion pipeline of the present utility model, it comprises metal flange pipe 1, at metal flange pipe 1 internal surface, be provided with corrosion-proof lining, at metal flange pipe 1 outer surface, be provided with asepticised outer layer, it is characterized in that above-mentioned corrosion-proof lining and asepticised outer layer have a right angle flanging at the flange covered section 2 of metal flange pipe 1 at place, right angle, the flange covered section 2 of corrosion-proof lining and asepticised outer layer is connected with sealer 3 at straightway with straight-tube portion 4.
