The joints commonly used in the explosion-proof flexible pipes at the price of such hazardous areas are all metal threaded live joints, all of which are made of metal flexible pipes, and some of them are on the outer surface of the surface. Rubber or a special sheath used by Nibb hose to wrap, coupled with the protection of steel wire mesh tube, in the entire explosion-proof operation process, to ensure the use of safety together with a certain degree of stability.
Explosion-proof flexible connecting pipe is used for its excellent explosion-proof function, and therefore most of the time is applied to the connection line between the explosion-proof products in some dangerous areas with flammable gas in the air and the electrical appliances, because it is used in more hours. In this type of area, therefore, it is necessary to have a certain explosion-proof function from the perspective of its application.
In addition, this explosion-proof flexible connecting pipe has its own excellent characteristics, flame resistance and oil resistance, and in the course of long-term use, it will not appear because of the time and corrosion appearance, and it has been eroded in water for a long time. There is no need to worry about the fact that it will lose its own explosion-proof function because of the external environment. According to scientific verification and determination by various parties, this type of explosion-proof flexible tube is superior in flexibility during use, and with its strong structural properties, it is then used to obtain superior explosion-proof and connection effects at work.
Under normal circumstances, because of the different application areas of such a flexible tube, the length of the flexible tube will be selected differently, generally 500, 700, 1000, etc. because of the use of such a flexible tube. Generally speaking, it is a relatively severe area with flammable dust. Therefore, the need for dust prevention is also relatively severe.
Explosion-proof flexible pipe connection equipment need to pay attention to what details
Excavation, oil refining, chemical industry, military, and other hazardous environments and the use of *** common explosion-proof flexible connections in offshore oil tanks, oil tankers and other hazardous locations, in order to allow the normal operation of the equipment, in addition to the quality of the equipment itself ** It is important that the explosion-proof flexible connecting pipe be equipped with equipment in a precise manner. So, what need to pay attention to in the equipment, how to do the equipment according to the following options:
1. It is not necessary to use a cable to seal joints on the two ends of the explosion-proof flexible connecting pipe. Both ends of the hose are equipped with explosion-proof live joints. The pipeline performance of the artificial equipment is good, and all the small details that need to be taken care of inside the pipeline can be handled well. In the equipment, the two ends of the pipe are lifted by hand, and then the construction personnel at the bottom of the tank perform the equipment. In the process of equipment, you need to apply some things, including ropes, rigs and so on.
2. With regard to the equipment of the explosion-proof flexible connecting pipe connecting pipe, it is necessary to pay attention to the two threads along the direction of the other end device, so that the explosion-proof flexible connecting pipe will not appear loose at both ends of the device during operation. Excellent cable passage.
3, after the explosion-proof flexible connecting pipe equipment, the length of the pipeline needs to be adjusted accordingly, adjust the backward, and then view the spacing of equipment and equipment or equipment and power supply position, try to make the pipeline adhere to vertical conditions, to avoid the emergence of Loss of appearance.
Explosion-proof flexible tube, also known as explosion-proof flexible connecting pipe, is suitable for the explosive mixture of IIBIIC grade T1-T6 groups, and is used as the connecting place of the explosion-proof electrical equipment's in-out line connection or steel pipe wiring bending.
MAX phase
MAX phase (including Ti3SiC2, Ti2AlC, etc.) is a new type of machinable ceramic material that attracts much attention
Phase MAX is A new type of ternary layered compound composed of three elements M, A and X. Its general chemical expression is MN+1AXN (where M: pre-transition metal, A: group A elements, X: carbon or nitrogen, N=1, 2, 3...). , both metal materials (excellent electrical conductivity, thermal conductivity, mechanical processing performance, thermal shock resistance, etc.) and ceramic materials (high modulus, high temperature resistance, oxidation resistance, corrosion resistance, etc.) excellent performance. In the past ten years, this field has been active in the international research, with remarkable progress, and its potential application in the field of energy and environment has been widely concerned. This research group mainly studies the synthesis of MAX phase materials, forming process and sintering technology and mechanism of high purity bulk materials
The material includes more than fifty ternary carbides or nitrides. M stands for transition metal element; A stands for main family element;
X stands for carbon or nitrogen. The basic formula can be expressed as M(n+1)AXn of which Ti3SiC2 has been the most widely studied.
Ti3SiC2 was synthesized by Barsoum's group from Drexel University in 1996 by hot pressing method, and its excellent performance was found.
Due to the unique nano-layered crystal structure, these materials are self-lubricating, highly ductile, electrically conductive and other properties.
This kind of material can be widely used as high temperature structure materials, electrode brush materials, chemical anticorrosion materials and
high temperature heating materials. After 1996, research related to this kind of material was widely carried out in Japan, Europe and China.
