You know? Fuzhou Acid and alkali resistant rubber hose Are there reinforcement regulations and requirements? Stainless steel welded air duct is a commonly used equipment, and its reinforcement actually has regulations and requirements, do you know? If in pipe support is adopted, the spacing between each support point and the edge or flange of the air duct shall be uniform, and the value shall not be greater than 950 mm. If the corrugated bars or wires are used for reinforcement, the arrangement should be regular and the spacing should be even. Moreover, there should be no obvious deformation and other problems for the board surface. If the welded air duct is reinforced, it should be made of ribbed bars, vertical bars, angle steel, flat steel, reinforcing bars and supports inside the duct. The appropriate one can be selected according to the actual situation and needs. If angle steel or reinforcing bars are used, they should also be arranged neatly and symmetrically. The height shall not be greater than the flange width. Principles and requirements for stainless steel air duct plate connection. When the thickness is less than or equal to 1mm, the splicing of plates shall be done by biting or riveting. When the thickness of plates is greater than 1mm, argon arc welding or electric arc welding shall be used instead of gas welding. The mature argon arc welding process of "single side welding, double side forming" shall be adopted; When assembling weldments, the welding materials and process measures selected for spot welding shall be consistent with the formal Acid and alkali resistant rubber hose Price The requirements are the same. The misalignment deviation of the pipe butt joint is less than 20% of the wall thickness and less than 2mm. Adjust the butt joint clearance, and do not use the method of heating, tensioning and twisting the pipe. It is not allowed to strike an arc or test the current on the weldment, and the pipe surface shall be free of arc scratch and other defects. Splash prevention measures shall be taken during welding. After welding, the slag and spatter shall be cleaned with stainless steel flat shovel. After welding, the slag on the weld surface and the spatter on both sides shall be cleaned.

“ wear-resisting Acid and alkali resistant rubber hose What are the applications in engineering transformation? " In this issue, we will explain this problem for you. Those who have consulted this problem will come to see it: First, we should consider the water supply and drainage of all water related equipment, such as wells, pumps, etc., their location, installation method and temperature, including galvanized air ducts. 2、 It is very important to consider galvanized air duct in advance to avoid temporary replacement of galvanized air duct materials. 3、 After the location of the machine tool is determined, the drainage outlet can be considered to be arranged underground, which is not only convenient but also durable. 4、 After river reconstruction, there should be a suppression test, but now many construction teams do not suppress the test. It is usually said that it is not important, that there is water and pressure in the galvanized air duct, and so on. Try to be present to suppress the test. 5. If the installation is completed, pay attention to the inspection of the workshop, water pump room and FRPP drain. If the drainage system is slow, the installation program should be able to open the installation. Water outlets should be protected, especially during civil engineering construction, Acid and alkali resistant rubber hose Price It may cause soil loss and blockage. I believe that you have a better understanding of this information, and we will continue to improve the galvanized air duct to make it more widely used.

Many people have never understood wear-resisting Acid and alkali resistant rubber hose It is better to use cast iron or rubber lining plate, so today I will give you a detailed analysis. The lining plate of the ball mill can tell you for sure that it is better to use rubber lining plate, which is also a trend for rubber lining plate to replace manganese steel lining plate. The rubber lining plate has many advantages that can not be achieved by manganese steel lining plates such as cast iron, so it has more advantages. One of the advantages of using cast iron or rubber liner for ball mill liner is that the noise of rubber liner is lower. In the process of grinding the rubber lining plate with materials, the noise is lower because it is not directly rubbed. Moreover, the rubber lining plate can throw the steel ball up for the second time to form the second grinding of materials, which makes the grinding of materials more thorough and the grinding fineness more uniform with good effect. In addition, the rubber lining plate can reduce the noise by an average of 30 dB compared with the noise of the cast iron lining plate, making it acceptable. Another important reason is energy saving. Energy consumption is an unavoidable problem for users of ball mills, because the cast iron lining plate is heavy in quality, Acid and alkali resistant rubber hose Price Therefore, when the motor drives the lining plate, it will consume a lot of power. The rubber used by the rubber lining plate itself is light, so the electric energy consumed by the motor when driving is very small, which can be more than 10000 yuan of electric energy a year.

Let's take a look today Fuzhou Acid and alkali resistant rubber hose How should the maintenance work be done? Firstly, the thickness of galvanized air duct splice plate shall be within the range specified in various specifications. If it is less than the thickness, it is easy to have defects such as cracking and wrinkling due to significant increase of bending force, abnormal damage of forming roll, overload of transmission system, boring, etc. Secondly, in the dedusting system: galvanized air ducts can be used for the collection and transportation of dedusting devices. In terms of air exhaust system: there is a large amount of smoke in the dining room, dining room and hotel kitchen, which needs air exhaust. The galvanized pipe is more appropriate, with good strength, economy and practicality. In air conditioning system: galvanized air duct can be pasted with thermal insulation materials, and the surface is beautiful. In bulk material transportation: in the pneumatic conveying system, some materials with fine loose particles can be transported by galvanized pipes, which has low cost and good effect. In the ventilation system: fresh air is supplied and discharged, harmful gases are discharged outdoors, and outdoor fresh air is sent indoors. The strength of stainless steel plate is greater than that of ordinary steel plate. When stainless steel plate is used for seaming, first of all, a forming test should be carried out to avoid overloading of equipment and excessive wear or mechanical problems. Due to the poor plasticity of aluminum plate, it is easy to crack when biting into forming. Forming test shall be conducted before construction. The last point is that the protection and decoration of the galvanized layer of the galvanized air duct can be significantly improved after passivation treatment, dyeing or brushing light protective agent. and Fuzhou Acid and alkali resistant rubber hose The fire prevention function of is mainly reflected in that it is nonflammable, but it should be noted that whether the insulation layer is burned depends on the material. We recommend that galvanized air duct materials use nonflammable insulation materials such as centrifugal glass wool.
