Now on the market Jining Oil resistant hose There are various models of galvanized air ducts. I believe you are familiar with galvanized air ducts. Do you know the main characteristics of galvanized air ducts? If you don't know, you can have a look. It will be helpful to purchase and use galvanized air ducts in the future. Galvanized air ducts refer to air supply, exhaust and smoke exhaust ducts used in hotels, shopping malls, textiles, chemical fiber, petrochemical, machinery manufacturing, instruments, electronics, medicine, tobacco, food, medical care, storage, office buildings, subway, civil air defense, basement and other projects. Its thickness and specification can vary according to requirements. Generally, when connecting, both ends of the galvanized spiral air duct are always externally connected to the accessories. Galvanized air duct metal air duct is made of various metal materials, commonly including galvanized iron sheet and stainless steel. With the continuous development of the tank industry at present, more and more industries and enterprises have applied to the tank industry, and more and more enterprises have entered the tank industry. Composite air ducts are composed of various inorganic materials, which can be divided into various types according to their composition, but most of them are lightweight, porous, and have large thermal resistance. First of all, the galvanized air duct is exquisite, compact, durable, beautiful, noble and elegant. The support and hanger of iron sheet air duct should be in the form and specification suitable for strength and rigidity according to the national standard atlas and specifications. The supports and hangers of extra wide, overweight and other special iron sheet air ducts with diameter or side length greater than 2500 mm shall be in accordance with the design regulations. Oil resistant hose Where can I find it? High quality galvanized sheet is used. Condensate water pan is molded by molding process. There are no welding seams, welding spots, and thermal insulation materials (applied to industry and buildings) that meet the fire protection standards are connected to the water pan as a whole. The galvanized air duct is small in size, and the installation of drainage pipes and lines is simple and convenient. The left and right connecting pipes and return air modes can be changed at any time to match the site conditions. Galvanized air duct can be installed in any space.

Let's take a look today Jining Oil resistant 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 Jining Oil resistant 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.

Jining Oil resistant hose Also called pu steel wire pipe, ventilation pipe, dust removal pipe, dust collection pipe, dust conveying pipe, industrial powder dust collection pipe, sweeping car dust collection pipe, drilling machine dust collection pipe, woodworking dust collection pipe, collectively called dust collection pipe. Therefore, industrial food dust transportation and industrial dust transportation are used for dust collection pipe. The production process structure of copper plated steel wire dust collection pipe is to wrap the pipe wall with solid elastic copper plated steel wire spirally, and the pipe wall material is coated with copper plated steel wire with special polyether PUR. PUR material is also called PU material. The thickness of pipe wall can be 0.4mm, 0.6mm, 0.9mm, 1.2mm, 1.5mm, 1.8mm and 2.1mm, depending on the customer's needs. Such as the temperature, wear resistance, flexibility and bending, hydrolysis resistance of the dust collection pipe. It is also necessary to consider whether static electricity is generated in the process of pipe full conveying dust to avoid unnecessary dust explosion and fire. Copper plated steel wire plastic coated dust collection tube is suitable for vacuum suction of powder and particle in industrial and mining, agriculture and water conservancy, civil engineering, food, petroleum, chemical industry, health and other industries, as well as transportation of water, oil, chemical materials, food, etc. Abrasive solids such as dust, powder, fiber, chip and particle, gas and liquid environment, for dedusting and suction plant, Oil resistant hose Where can I find it? Industrial vacuum cleaners, paper and textile fibers, are used as protective tubes. It is widely used in farmland irrigation, industry and mining, oil depot, sand extraction, sand blasting, food, medicine, indoor gas, powder, dust absorption and emission and other fields. This product is a substitute for PVC, rubber and metal pipes.

You know? Jining Oil resistant 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 Oil resistant hose Where can I find it? 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.
