Characteristics Of Large-diameter Carbon Steel Flat Welding Flange.

Characteristics of large-diameter carbon steel flat welding flange. Large diameter carbon steel flat welding flange is a kind of flange, which is widely used and promoted in the machinery industry, chemical industry, wind power industry and sewage treatment industry, and has been praised and favored by users. The large diameter flat welding flange is widely used. Production process is divided into rolling and forging, very large can only be rolling. Large diameter flange is common in addition to flat welding flange and butt welding flange. In the real production and sales, or the proportion of flat welding products accounted for more. The structure and use scope of flat welding and large diameter welding flange are different, and the characteristics and advantages can be different, so it should be used for different ranges to ensure that the flange plays an important role. Large diameter carbon steel flat welding flange is poor steel, suitable for pressure p 4MPa; different nature of flange fittings in different fields have good product performance, different occasions and space, different effects. Large diameter carbon steel flat welding flange is a better welding kind, because the pipe and flange are good to vertical, the pipe will not incline. Large diameter welding flange is not all need internal and external double-sided welding, there is no special requirements are generally just a welding. Large diameter carbon steel flat welding flange is a hollow inner hole processed slightly larger than the outer diameter of the pipe, the pipe is inserted inside the welding. Large diameter butt welding flange is the pipe diameter and wall thickness of the interface end is the same as the pipe to be welded, just the same as the two pipes are welded. Large diameter carbon steel flat welding flange clearance and surface treatment, remove the flange clearance and screw floating rust with a brush; clean the flange clearance with compressed air; if using chemical rust prevention agent, chemical rust resistance agent affects the flange seal. When installing the large diameter flange, operate according to the above installation principles and requirements.
