AI Technical Summary

Problems solved by technology

However, the heat exchange tubes are generally made of polytetrafluoroethylene materials, which are all in the form of straight tubes. In the working state, due to the influence of thermal expansion and contraction, the connection between the heat exchange tubes and the tube sheet will fall off. Phenomenon, and when the work is running, the vibration is relatively large, and it is easy to cause shedding

Embodiment Construction

[0021] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Please combine Figure 1 ~ Figure 4 As shown, a shock absorbing tube of the present invention includes a tube body 1 made of high temperature resistant and corrosion resistant material, and the tube body 1 has a bellows section 2 on it. As an example, the bellows section 2 is a section, located in the middle of the pipe body 1 (see image 3 shown) or on one end (see figure 1 shown). As an example, the bellows section 2 is two sections, which are respectively located at both ends of the pipe body 1 (see figure 2 shown) or spaced on the tube body 1 (see Figure 4 shown). Of course, the bellows can also be multi-sections, which are arranged on the pipe body 1 at intervals. The bellows section 2 can effectively reduce adverse effects caused by thermal expansion and contraction, and vibration.

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

technical field [0001] The present invention relates to a pipe material, more specifically, to a shock absorbing pipe. Background technique [0002] PTFE is one of the most corrosion-resistant materials in the world today. It has the characteristics of a wide temperature range, a small friction coefficient, and no adhesion to any substance. It is an ideal material for manufacturing heat exchangers with strong corrosive chemical media, but this This material also has serious defects such as small thermal conductivity, low pressure resistance, and large thermal expansion coefficient. [0003] Shell and tube heat exchanger is a commonly used heat exchange equipment, and the heat exchange tube is made of polytetrafluoroethylene material, which has strong acid and alkali corrosion resistance, high and low temperature resistance, high strength, With the advantages of light weight and long life, it is widely used in chemical, mechanical, pharmaceutical, electronic and other indust...
