Abstract

The invention discloses a vibration reducing pipe. The vibration reducing pipe comprises a pipe body; the pipe body adopts a high-temperature-resistant and corrosion-resistant material; and a corrugated pipe section is arranged on the pipe body. The adverse effect caused by thermal expansion and cold shrinkage and vibration can be effectively reduced through the corrugated pipe sections; some use demands under such bad working conditions as high temperature and high corrosion can be satisfied; and in particular, the vibration reducing pipe manufactured by such fluorine-contained plastic materials as PTFE, FEP, PFA or PVDF is used for a heat exchange tube, can satisfy the heat exchange working conditions of high-temperature resistance and corrosion resistance, and can achieve the effect of effective vibration reduction and elimination of such adverse effects as thermal expansion and cold shrinkage.

Description

A kind of damping tube
Technical field
The present invention relates to a kind of tubing, more particularly, it relates to a kind of damping tube.
Background technology
Politef is the world today's one of corrosion-resistant material, there is temperature resistant range one wide, coefficient of friction is little, do not adhere to the features such as any material, it it is the ideal material manufacturing severe corrosive chemical mediator heat exchanger, but it is little that this material exists thermal conductivity coefficient simultaneously, resistance to force down, the major defects such as thermal coefficient of expansion is big.
Shell-and-tube heat exchanger is a kind of conventional heat-exchange apparatus, and heat exchanger tube therein uses the shell-and-tube heat exchanger that polytetrafluoroethylmaterial material manufactures, there is the advantages such as acid and alkali-resistance deep-etching, high-low temperature resistant, high, lightweight, the life-span length of intensity, be used widely in industries such as chemical industry, machinery, medicine, electronics.But typically use polytetrafluoroethylmaterial material to make heat exchanger tube, be all straight tube form, in working, because being affected by expanding with heat and contract with cold, result in the phenomenon that the connection between exchanger tubes and tubesheets falls off, and work operation time, vibrate the biggest, also easily cause obscission.
Summary of the invention
For drawbacks described above present in prior art, it is an object of the invention to provide a kind of damping tube, it is possible to reduce and expanded with heat and contract with cold, shake and the harmful effect that causes.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of damping tube, including body, body is high temperature resistant, resistant material, and described body has bellows piece.
Described high temperature resistant, resistant material are fluoro-containing plastic material.
Described fluoro-containing plastic material is PTFE, FEP, PFA or PVDF.
Described bellows piece is one section, is positioned on centre or one end of body.
Described bellows piece is two sections, lays respectively on the two ends of body or interval is located on body.
Described corrugated tube is multistage, and interval is located on body.
Described bellows piece and body are formed in one structure.
Described bellows piece and body are Split type structure, are connected by hot sealing.
A kind of damping tube is as heat exchanger tube application in heat exchanger.
The damping tube of the present invention includes body, body is high temperature resistant, resistant material, on described body, there is bellows piece, can effectively be reduced by bellows piece and be expanded with heat and contract with cold, the harmful effect shaken and cause, disclosure satisfy that some are such as high temperature, use demand under the bad working environments such as high corrosion, especially with PTFE, FEP, the damping tube that the fluoro-containing plastic materials such as PFA or PVDF make, heat exchanger tube for heat-exchange apparatus, it is not only able to meet high temperature resistant, corrosion resistant heat-exchanging state, but also effective damping can be played, elimination such as is expanded with heat and contract with cold at the dysgenic effect.

Fig. 5 is the schematic diagram that the damping tube of the present invention is applied to shell-and-tube heat exchanger.
Detailed description of the invention
Technical scheme is further illustrated below in conjunction with the accompanying drawings with embodiment.
Incorporated by reference to shown in Fig. 1~Fig. 4, a kind of damping tube of the present invention, including body 1, body 1 is high temperature resistant, resistant material, and described body 1 has bellows piece 2.As an embodiment, described bellows piece 2 is one section, is positioned at (see figure 1) on the centre (as shown in Figure 3) of body 1 or one end.As an embodiment, described bellows piece 2 is two sections, lays respectively on the two ends of body 1 (as shown in Figure 2) or interval is located on body 1 (as shown in Figure 4).Certainly, described corrugated tube can also be multistage, and interval is located on body 1.Can effectively be reduced by bellows piece 2 and be expanded with heat and contract with cold, shake and the harmful effect that causes.
Above-mentioned high temperature resistant, resistant material can use fluoro-containing plastic material or other similar material, it is possible to meet some such as the use demand under the bad working environments such as high temperature, high corrosion.
And above-mentioned fluoro-containing plastic material can use but be not limited only to PTFE, FEP, PFA or PVDF or etc. fluoro-containing plastic.Using these materials, it is high temperature resistant, corrosion resistance is the most prominent, can be widely applied under the bad working environments such as high temperature, high corrosion, such as blast furnace heat-exchanging state etc..
Additionally, described bellows piece 2 can use integrated formed structure with body 1, can also use bellows piece 2 and body 1 is Split type structure, connected by hot sealing, the hot pressing temperature that hot sealing connects is 180 DEG C to 315 DEG C, hot pressing pressure is 0.1MPa to 16MPa, and the hot-forming time is 1min to 100min.
Shown in Fig. 5 is that the damping tube using the present invention is as the heat exchanger tube 3 application in shell-and-tube heat exchanger 4, can be naturally also applied on the heat exchanger tube of other heat exchanger, it is not only able to meet heat-exchanging state high temperature resistant, corrosion resistant, but also effective damping can be played, eliminate dysgenic effects such as expanding with heat and contract with cold.
Those of ordinary skill in the art will be appreciated that, above embodiment is intended merely to the present invention is described, and it is not used as limitation of the invention, as long as in the spirit of the present invention, change, the modification of embodiment described above all will be fallen in the range of claims of the present invention.
