Abstract
The utility model discloses a wear-resistant metal corrugated pipe expansion joint. The wear-resistant metal corrugated pipe expansion joint comprises two connection pipes and a corrugated pipe connected between the connection pipes; a first ceramic layer is also formed on the inner wall surface of each connection pipe. A lining pipe is also arranged in the corrugated pipe; the two ends of the lining pipe respectively extend into the connection pipes; and a second ceramic layer is formed on the inner wall surface of the lining pipe. According to the utility model, both the connection pipes and the lining pipe are made of ordinary Q235 steel plates, and then wear-resistant ceramics are added, so that the wear resistance of the wear-resistant metal corrugated pipe expansion joint provided by the utility model is improved, and the service life of a product is prolonged.
Description
Technical field
The utility model relates to a kind of expansion joint, relates in particular to a kind of antifriction metal (AFM) bellows expansion joint.
Background technique
The additional stress that expansion joint causes because of temperature difference and mechanical vibration for compensation, and be arranged on a kind of flexible structure on container shell or the pipeline.Because it is as a kind of elastic compensating element that can freely stretch, advantages such as reliable operation, functional, compact structure have been widely used in departments such as chemical industry, metallurgy, nuclear energy.Expansion joint also is slip joint traditionally; Or corrugated expansion joint; Be that effective dilatation in order to the elastic element that utilizes corrugated expansion joint absorbs pipeline, conduit or the container a kind of compensation device by former thereby the dimensional changes that produces such as expand with heat and contract with cold, belong to a kind of compensating element.Can be to axially, laterally and the absorption of angular displacement, be used for adding thermal walking, mechanical displacement absorbed oscillation, reduce noise etc. in pipeline, equipment and system.The additional stress that expansion joint causes because of temperature difference and mechanical vibration for compensation, and be arranged on a kind of flexible structure on container shell or the pipeline.Because it is as a kind of elastic compensating element that can freely stretch, advantages such as reliable operation, functional, compact structure have been widely used in departments such as chemical industry, metallurgy, nuclear energy.The expansion joint that on container, adopts has various ways, with regard to the shape of ripple, uses the most extensively with the U-shaped expansion joint, secondly also has Ω shape and C shape etc.And the expansion joint that on pipeline, adopts has universal, pressure balance type, hinge type and universal joint formula etc. again with regard to structure compensation.Bellows expansion joint is a kind of expansion joint of processing with metal bellows.It can be flexible along axial direction, also allows a small amount of crooked.But bellows expansion joint is in use, can easy abrasion, and especially under the condition of high temperature, the process that regular experience is expanded with heat and contract with cold, it is especially serious to wear and tear.This has had a strong impact on the life-span of expansion joint.
The model utility content
The utility model technical problem to be solved is the deficiency to above-mentioned existing technology, and a kind of expanding with heat and contract with cold of can bearing is provided, and nonabradable antifriction metal (AFM) bellows expansion joint.
For solving the problems of the technologies described above, the technological scheme that the utility model is taked is: this antifriction metal (AFM) bellows expansion joint, comprise two bellowss of taking over and being connected between the adapter, and it is characterized in that: on the internal face of taking over, be provided with first ceramic layer.
As the further improved technological scheme of the utility model, in bellows, also be provided with internal lining pipe, the two ends of internal lining pipe are stretched into respectively in the adapter, and the internal face of said internal lining pipe is provided with second ceramic layer.
The sheet material that adapter of the utility model and internal lining pipe adopt is common Q235 steel plate, adds wear-resisting pottery then, has improved the wear resistance of the utility model antifriction metal (AFM) bellows expansion joint, has prolonged the working life of product.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the local enlarged diagram at A place among Fig. 1.
Be described further below in conjunction with the embodiment of accompanying drawing the utility model.
Embodiment
Referring to Fig. 1, this antifriction metal (AFM) bellows expansion joint comprises two adapters 1 and is connected the bellows of taking between 12, on the internal face of adapter 1, is provided with first ceramic layer 3.In bellows 2, also be provided with internal lining pipe 4, the two ends of internal lining pipe 4 are stretched into respectively and are taken in 1, and the internal face of said internal lining pipe 4 is provided with second ceramic layer 5.Internal lining pipe 4 and take over 1 between leave the slit, the edges at two ends of internal lining pipe 4 is tightly connected with first ceramic layer 3 and second ceramic layer 5 respectively.First ceramic layer 3 is close to adapter 1 internal face by a plurality of ceramic plates to be formed, and second ceramic layer 5 is made up of the internal face that a plurality of ceramic plates are close to internal lining pipe 4, and ceramic plate adopts the high ceramic plate of wear resistance on the existing market.
Claims (2)
1. an antifriction metal (AFM) bellows expansion joint comprises two adapters (1) and is connected the bellows (2) between the adapter (1), it is characterized in that: on the internal face of taking over (1), be provided with first ceramic layer (3).
2. antifriction metal (AFM) bellows expansion joint according to claim 1; It is characterized in that: in bellows (2), also be provided with internal lining pipe (4); The two ends of internal lining pipe (4) are stretched into respectively in the adapter (1), and the internal face of said internal lining pipe (4) is provided with second ceramic layer (5).
