Problems solved by technology

Due to the flow resistance of the fluid medium in the compensator and the high-speed flow of the medium in the existing corrugated compensator, it is easy to cause corrugated induced vibration
In addition, the medium chloride ion content in the delivery pipeline is too high, which has a strong corrosion effect on the stainless steel pipe of the corrugated compensator, directly affecting its service life, resulting in a serious reduction in the service life of the corrugated compensator

Embodiment Construction

[0009] The present invention will be described in detail below in conjunction with the drawings and specific embodiments:

[0010] As shown in Figure 1, the bellows 1 and the end pipe 2 are connected to form an integral structure. The bellows 1 is provided with an inner sleeve 3, and the inner surface of the inner sleeve is evenly sprayed with an anticorrosive layer 4, and the outer ends of the end pipes There are flanges 5 on the surface, and the flanges are integrated with the end pipe. Several reinforcing ribs 6 are installed on the flanges. The reinforcing ribs can be ordinary bolts. The outer surface of the corrugated pipe 1 is evenly sprayed with an anti-corrosion layer 7. In addition, the filling between the corrugated pipe and the inner sleeve can also be provided with a layer of heat-resistant and heat-resistant material. The structure of the bellows 1 can be U-shaped, single-layer, double-layer, and multi-layer; the type of corrugated compensator can be single axial type...

Abstract

The invention relates to the technical field of a corrugation compensator, especially a vibration-proof corrugation compensator, which comprises a sylphon bellowss and a side tube which are connected into an integral structure. The invention is characterized in that an inner sleeve is arranged in the sylphon bellowss, and the inner surface of the inner sleeve is uniformly sprayed with an anticorrosion coating. The external surfaces of both ends of the side tube are provided with a flanging which is integrated with the side tube, and a plurality of stiffeners are arranged on the flanging. The invention has the advantages of compact structure, strong pressure bearing capacity, acid, alkali and chloride corrosion prevention, high temperature resistance, heat insulation prevention, etc, which prevents the flow resistance of flow media in the compensator and the induced vibration of the sylphon bellowss caused by high speed flow of the media and extends the service life.

Description

[Technical Field] [0001] The invention relates to the technical field of a corrugated compensator, in particular to an anti-vibration corrugated compensator. [Background technique] [0002] Corrugated compensators have a wide range of applications, such as metallurgy, petroleum, chemical, thermal power, heating and water supply, gas and other pipeline systems or pipe networks, and there is a great potential for market demand. The corrugated compensator is usually made of stainless steel as the core element of the corrugated pipe. Existing corrugated compensators can easily cause ripple-induced vibration due to the flow resistance of the fluid medium in the compensator and the high-speed flow of the medium. In addition, the medium chloride ion content in the conveying pipeline is too high, which has a strong corrosive effect on the stainless steel pipe of the corrugated compensator, which directly affects its service life and causes a serious reduction in the service life of the c...
