Industrial pollution is a signal of environmental protection. These industrial pollution must be environmentally friendly. These equipment and machinery, insulation air valve pollution sources and discharge routes must be applied to the pipeline. Changzhou Rubber hose It is just one of the rare ventilation ducts. Let's take a look at the precautions of stainless steel pipe welding process. Stainless steel welded air duct is called welding nano, which is a kind of welding nano. Since the thickness of the pipe is 0.8-5.0mm, welding is rare in the market (the thickness of the seamless pipe formed in the steel plant is 5-30mm), which is different. It can be said that it is a thin wall welding nano. As the thickness of welded pipe, the thickness of welded pipe may not be required to be the same as that of seamless welding, but only to meet the national standard of ventilation pipe, and at the same time meet the requirements of full pressure and air volume in the ventilation system. In the application environment, the thickness of stainless steel welded air duct pipes can be customized according to the requirements of the enterprise factory (the demander) to adapt to the processing of welded pipes. In short, as long as the above requirements are met, the cost of the enterprise will be lower. As long as the enterprise factory knows that it needs more air volume to customize and sell the fan, and then press the full pressure and air volume of the fan, the welding size of the stainless steel pipe can be determined. Because of the small wind resistance of round air ducts, ordinary air ducts are rarely used to connect environmental protection equipment. even if wear-resisting Rubber hose The air outlet of the equipment is square or round (also called square turn). Circles, heaven and earth, cylindrical dampers and circular places are connected to fans and air ducts. In this case, the circular pipe is very good for installation.

At present, the common air ducts in the domestic market are generally made of galvanized iron sheet, commonly known as white iron sheet. wear-resisting Rubber hose And the thickness is 0.44~1.22mm. The thickness of iron sheet of air duct in China is generally less than 1.5mm, and the thickness of zinc coating refers to the national standard GB/T 13912-2002: 35 μ m. Average 45 μ m。 During the production of galvanized air duct, the national standard requires us to understand the following figures: 1. Appearance: conduct appearance inspection on all hot galvanized parts, and the main surface should be smooth, free of falling off, roughness and zinc spikes (if these zinc spikes will cause damage), free of peeling, missing plating, and residual solvent residue, There shall be no zinc lump and zinc ash in the parts where hot galvanized workpieces are used or where they are corrosion resistant. Note: "Roughness" and "smoothness" are relative concepts, and the coating roughness of workpiece is different from that of mechanical roller or (and) blow molding and galvanized products (such as galvanized steel plate and galvanized steel wire). As long as the coating thickness is greater than the specified value, there may be dark or light gray uneven areas on the surface of the plated parts. White rust (mainly white or gray corrosion products of alkaline zinc oxide) is allowed on the surface of galvanized workpieces stored in wet conditions. 2. Thickness: quantitative sampling shall be carried out according to the specified test method for coating thickness test. According to the size of the main surface area of hot-dip galvanized parts, the coating thickness measured in the test shall meet the following requirements: A) For parts with the main surface area greater than 2m (i.e. large parts), the average coating thickness measured on all basic measured surfaces of each part in the sample shall not be less than the minimum value of the corresponding average coating thickness: B) For parts with the main surface area less than 2m, Rubber hose Where can I find it? The local coating thickness measured on each basic measuring surface shall not be less than the minimum local thickness, and the average coating thickness measured on all basic measuring surfaces of the sample shall not be less than the corresponding minimum average thickness.

With the rapid development of the national economy and the continuous improvement of the technical level, almost all walks of life need to do exhaust ventilation systems, Changzhou Rubber hose What are the advantages worth pursuing? 1. The welding method is unique. It adopts a new low temperature welding form, which does not damage the galvanized layer of the product. The welding spot is firm, the weld seam is beautiful, and the sealing is good. After welding, no treatment is required for the weld seam. 2. The manufacture of mechanically formed air duct makes the high-quality galvanized sheet not damaged, and the galvanized layer not damaged, thus prolonging the service life. 3. The specification is uniform and the size is standard, which ensures that the inner wall of the pipeline is flat and smooth, so that it is easy to clean and the material transportation is smooth. 4. The self forming flange can make the pipe material uniform, no longer use angle steel flange, and reduce the pipe weight by more than 20%, so the load bearing capacity of the building can be greatly reduced, thus reducing the overall cost of the building. 5. Enhance the beautiful pipeline, beautiful appearance, exquisite structure, smooth lines, superior performance, and the installation of exposed air ducts, especially suitable for this product. 6. Typical round air pipe fittings are generally 3-6 meters long and rectangular pipe fittings are 1-1.5 meters long, reducing the connection points of pipe fittings and minimizing the leakage at the joint of pipe fittings. 7. The pipe fittings, joints and spare parts made by mechanized assembly line all have standard sealing rings. As they are produced in a standardized and factory way, they have better air tightness. 8. Mechanically formed compression ribs and stiffeners can improve the strength of the pipe wall, save material thickness and reduce costs. The thickness of the seam of the spiral pipe is 4 times that of the pipe body, which makes the pipe very rigid and has the best pressure bearing performance, especially the negative pressure. 9. Scientific joint and seaming methods can ensure smooth pipeline gas without affecting pipeline flow diameter. Therefore, mechanized assembly line production improves production efficiency and effectively shortens delivery cycle. Advanced computer process control program blanking, production, Rubber hose Where can I find it? It ensures the dimensional accuracy of pipeline components, thus ensuring fast and convenient installation and construction, and improving work efficiency and economic benefits.

Comprehensive evaluation of world conveyor belt wear-resisting Rubber hose The development level and the application practice of large industrial and mining enterprises in China, in the future, the technology and market development of conveyor belt vulcanizers in China will show the following eight characteristics: more intelligent: Canada Xiaoai Group has recently launched a new X-PAD conveyor belt vulcanizer control system, which uses full touch color screen control, and one operating system can implement real-time monitoring on multiple pairs of vulcanizer heating plates, And it can conduct remote monitoring through WIFI.
