Appearance color, use and precautions of A105 BL large caliber flange
A105 BL large diameter flange is one of the flanges widely used in machinery, chemical industry, wind power, sewage treatment and other industries, and is welcomed and favored by users, its production process is divided into rolling and forging, very large can only be rolling, materials for carbon steel, stainless steel and alloy steel. Since the exterior color of the A105 BL large-caliber flange has nothing to do with the quality, the surface treatment of the flange exterior is only the color of the antirust oil, but not the color of the material of the product itself. However, the production date of the product can also be judged by the color of the A105 BL large caliber flange appearance. If the production date is long, the antirust oil will penetrate into the product interior, will present the old color, the appearance is not so fresh, but this does not mean that the quality of the product has a problem. For the measurement standard of large caliber flange, every manufacturer and even everyone is different, some people think that the caliber of 600 above is a large caliber, and some people think that 800 above, of course, most people will take 600 as the standard line. A105 BL large diameter flange is wide in use, the use range is determined according to different characteristics, mostly used in the case of relatively moderate medium conditions, such as low-pressure non-purified compressed air, low-pressure circulating water, its advantage is relatively cheap. What are the precautions for using large-caliber flanges? A105 BL large diameter flange is used for flange and pipe matching welding, mainly used in welding technology, good performance of use characteristics and performance, reasonable structure, strength and stiffness, withstand high temperature and repeated bending and temperature fluctuation, reliable sealing, roll flange with nominal pressure of 0.25~2.5MPA using concave and convex sealing surface.
