Abstract
The utility model discloses a wear-resisting pipe and a wear-resisting elbow pipe. The wear-resisting pipe and the wear-resisting elbow pipe respectively comprise a steel pipe body, wherein, an inner wall of the steel pipe body is provided with a wear-resisting ceramic paint inner covering, as an improvement, the wear-resisting ceramic paint inner covering is provided with a metal mesh therein, the metal mesh is welded and fixed to the inner wall of the steel pipe body. The wear-resisting pipe and the wear-resisting elbow pipe have a simple structure, and have the beneficial effects that: the wear-resisting ceramic paint inner covering is in seamless connection with the steel pipe body, so that the wear-resisting ceramic paint inner covering is not easy to drop in an operation process, after the wear-resisting ceramic paint inner covering is worn, the external steel pipe body can be reused.
Description
Technical field
The utility model relates to pipe and the bend pipe tools of making pipeline, especially a kind of wear-resisting pipe and wear-resistant bend pipe fitting of making wind powder medium transfer canal.
Background technique
Be used in the existing technology make wear-resisting pipe and the wear-resistant bend pipe fitting that transmits wind powder medium pipeline, be employed in more and install abrasionproof alloy sheets or abrasionproof ceramic plate in the steel casing additional, the shortcoming of this pipe is that the wear strip integrality that edge pastes in the steel casing body is bad; There is seam the centre, and medium gets into the gap between frame and wear strip from seam crossing easily, causes the loosening or deformed damaged of wear strip; In equipment running process; The wear strip that edge pastes comes off easily, causes pipeline obstruction, and the cost of this wear-resisting pipe and wear-resistant bend pipe fitting is high; Can not repair after the wear strip wearing and tearing in wear-resisting pipe and the wear-resistant bend pipe fitting; Can only disposablely use, cause waste, be unfavorable for reducing production costs.In addition, because wear-resisting pipe of the prior art and wear-resistant bend pipe fitting adopt flange to connect or welding more, therefore, have that construction is inconvenient, defectives such as waste of manpower resource and time.
The model utility content
The technical problem that model utility will solve is: a kind of wear-resisting pipe and wear-resistant bend pipe fitting are provided; This wear-resisting pipe and wear-resistant bend fitting structure are simple; The seamless connection between wear-resistant liner layer and steel body; Wear-resistant liner layer difficult drop-off in running, after the wearing and tearing of wear-resistant liner layer, outer steel tubulation body can utilize once more.
The technological scheme that the technical solution problem is taked:
A kind of wear-resisting pipe and wear-resistant bend pipe fitting comprise the steel body, are provided with the wearable ceramic coat inside liner at the inwall of steel body.
Improvement as the utility model:
In the wearable ceramic coat inside liner, be provided with metal and hang net, metal is hung net and is weldingly fixed on the steel inboard wall of tube body.
At the crooked position of wear-resistant bend pipe fitting, wearable ceramic coat inside liner thickness is greater than wearable ceramic coat inside liner thickness on the intrados on the outer arced surface.
The thickness of wearable ceramic coat inside liner is 20-50mm.
On the outer wall of the steel body end of wear-resisting pipe and wear-resistant bend pipe fitting, be provided with the Connection Card annular groove.
Beneficial effect: wear-resisting pipe of the utility model and wear-resistant bend pipe fitting; Owing to adopted said wear-resisting pipe and wear-resistant bend pipe fitting to comprise the steel body, be provided with the technological scheme of wearable ceramic coat inside liner at the inwall of steel body, make seamless connection the between wear-resistant liner layer and the steel body of wear-resisting pipe and wear-resistant bend pipe fitting of the utility model; Wear-resistant liner layer difficult drop-off in running; After the wearing and tearing of wear-resistant liner layer, only need to repair or make the wear-resistant liner layer again to get final product, and outer steel tubulation body can utilize once more; Therefore, the cost of production and the maintenance expenses of equipment have been reduced; Owing to adopted and in the wearable ceramic coat inside liner, be provided with metal extension net; Metal is hung net and is weldingly fixed on the technological scheme on the steel inboard wall of tube body; Further strengthened the intensity that the wearable ceramic coat inside liner is connected with the steel body; Prevent that the wearable ceramic coat inside liner from coming off, prolonged the working life of wear-resisting pipe and wear-resistant bend pipe fitting, improved the Safety performance of equipment operation; Owing to adopted crooked position at the wear-resistant bend pipe fitting; Wearable ceramic coat inside liner thickness is greater than the technical characteristics of wearable ceramic coat inside liner thickness on the intrados on the outer arced surface; Thickness through the direct wash surface wearable ceramic coat of wind-engaging powder medium inside liner in the suitable increase wear-resistant bend pipe fitting; Further prolong the working life of wear-resistant bend pipe fitting, reduced the operation and the maintenance cost of equipment; Owing to reasonably define the thickness of wearable ceramic coat inside liner, make cost of production, wear-resisting property, the working life three of wear-resisting pipe and the wear-resistant bend pipe fitting of the utility model reach best fit; Owing to adopted on the outer wall of the steel body end of wear-resisting pipe and wear-resistant bend pipe fitting; Be provided with the technical characteristics of Connection Card annular groove; Through Joining clasp wear-resisting pipe or wear-resistant bend pipe fitting are connected; Make the attended operation simple and effective, can practice thrift the great amount of manpower resource, shorten the engineering time.
