Large-bore ASME B16.47 flange wear reduction method
Large diameter ASME B16.47 flanges are common with flat and butt welding flanges. There are no large-caliber wire buckle flanges. In the real production and sales, or the proportion of flat welding products is much larger. Flat welding large diameter welding ASME B16.47 flange and large diameter welding ASME B16.47 flange structure and use range is different, can show the characteristics and advantages will be different, so it should be used for different ranges, to ensure that the flange plays an important role. The measures for severe wear of large diameter ASME B16.47 flanges include: reasonable design of structural shape and size of mechanical parts to reduce the pressure and relative motion speed between the relative moving surface; select appropriate materials and heat treatment; adopt appropriate lubricants, additives and their supply method; when working under pollution, dust conditions, add necessary sealing or protective devices, and improve the working and assembly accuracy to avoid local wear and tear. Reduce wear on large-caliber ASME B16.47 flanges: First, Reasonable mechanical design structure can help us to reduce the pressure and wear between the flange surfaces; 2. The material and heat treatment process of the large diameter ASME B16.47 flange also affect the overall quality of the flange; 3. If the flanges work in a dusty or polluted environment, The necessary dustproof devices and seals should be added; 4. General methods to reduce mechanical wear, Use of lubricant is also essential, For the large-caliber ASME B16.47 flanges, Can use fluid static lubrication and fluid dynamic pressure lubrication way to handle; 5. You can also use a more technical accurate maglev support to solve this problem. When the large diameter ASME B16.47 flange production is completed, the latter process is to apply antirust oil on the flange surface, which is an essential process, the purpose is to prevent the flange in contact with water after rust, affecting the appearance of the product.
