Description
Technical field
The utility model relates to a kind of silicon carbide wear-resistant anticorrosion composite pipe, belongs to abrasion-proof pipe field.
Background technique
In the Cemented filling operating mode that deep-etching and wear-resisting property require, existing wear-resisting, anti-corrosion pipeline only comprises armor and wear-and corrosion-resistant layer, by high-abrasive material as inside liner, matrix uses the metallic material after derusting by sandblasting, be combined with metallic matrix by glue mode, using high-abrasive material as working surface fed sheet of a media.But, because gap (especially obvious when being subject to temperature variation) easily appearring in the inner wear-and corrosion-resistant layer of common anti-corrosion pipe, internal flow acid-alkali medium being leaked and cause armor to corrode, finally causing whole pipeline to lose efficacy.
Model utility content
The technical problems to be solved in the utility model is: provide a kind of multiple tube working life of improving, ensure armor by the erosion of medium, is applicable to carry containing admittedly washing away, the silicon carbide wear-resistant anticorrosion composite pipe of aggressive medium.
Silicon carbide wear-resistant anticorrosion composite pipe described in the utility model, comprise armor, armor adopts metal pipe, armor inside arranges anticorrosion separation layer, anticorrosion separation layer inside arranges wearing layer, armor end arranges adpting flange, and wearing layer is segmented silicon carbide ceramic, adopts wear-resisting glue composite to carry out filling and pasting between adjacent carbons SiClx stoneware pipe.
Carborundum composite pipe adopts multilayer materials, and namely armor adds anticorrosion separation layer and adds wearing layer, and wherein, armor adopts metal pipe, under the support of outer wall steel pipe, meet requirement of strength completely; The structure of anticorrosion separation layer, plays the anti-corrosion function to armor, can resistance to strong acid, highly basic, strong oxidizer, and inner wear resistance lining adopts silicon carbide sintered ceramic pipe, not with inorganic acid reaction, has high wear resistance, and opposing thermal shock, can not be cracked.
Described anticorrosion separation layer adopts teflon, silica gel, polyethylene or polypropylene.Can resistance to strong acid, highly basic, strong oxidizer, there is anti-corrosion function.
Described material is teflon, the end of polyethylene or polyacrylic anticorrosion separation layer pipe arranges flange.The design of flange, effectively isolates internal corrosion flowing medium and armor in pipe end sealing place, and the alignment be simultaneously convenient between pipeline is installed.
Described material is that the anticorrosion separation layer of silica gel is set to overall structure.When material is silica gel, after armor and wearing layer are fixed, adopt injection mode to form integral type wear-resistant structure, play wear-resisting effect.Adopt Flange joint between pipeline and pipeline, and adopt corrosion-resistant teflon pad.
The surface hardness of described wearing layer is HRC91-95.There is high wear resistance, and opposing thermal shock, can not be cracked, realize conveying containing the medium admittedly washing away, corrode.
The beneficial effects of the utility model are:
Carborundum composite pipe adopts wearable silicon nitride stoneware pipe to be liner, greatly can improve multiple tube working life, utilize isolation and the continuity of anticorrosion tubing simultaneously, ensure that armor by the erosion of medium; Armor support under meet requirement of strength completely; Be applicable to carry the medium containing admittedly washing away, corroding.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure for amplifying schematic diagram of part A in Fig. 1.
In figure: 1, armor 2, anticorrosion separation layer 3, wearing layer 4, adpting flange 5, flange.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Fig. 1 ~ Fig. 2, silicon carbide wear-resistant anticorrosion composite pipe described in the utility model, comprise armor 1, armor 1 adopts metal pipe, armor 1 inside arranges anticorrosion separation layer 2, and anticorrosion separation layer 2 inside arranges wearing layer 3, and armor 1 end arranges adpting flange 4, wearing layer 3 is segmented silicon carbide ceramic, adopts wear-resisting glue composite to carry out filling and pasting between adjacent carbons SiClx stoneware pipe.Anticorrosion separation layer 2 adopts teflon, silica gel, polyethylene or polypropylene.Material is teflon, the end of polyethylene or polyacrylic anticorrosion separation layer pipe arranges flange 5.Material is that the anticorrosion separation layer 2 of silica gel is set to overall structure.The surface hardness of wearing layer 3 is HRC91-95.
When material is teflon, polyethylene or polyacrylic anticorrosion separation layer pipe, first fill armor 1, then anticorrosion separation layer 2 is refilled, finally wearing layer 3 is installed, when material be silica gel anticorrosion separation layer time, first fill armor 1 and wearing layer 3, inject silica gel finally by injection mode, form wearing layer 3.
