1. The butt welded flange is the diameter and wall thickness of the pipe at the interface end and the pipe to be welded, just like the two pipes. The flat welded flange is a concave table machined at the interface slightly larger than the outer diameter of the pipe, and the pipe is inserted inside the welding. The welding performance of butt welding is better, and the corrosion is relatively small.
2, Flat welding and butt welding is the flange and pipe connection welding mode, flat welding flange welding only one side welding does not need to weld the pipe and flange connection of the inner mouth, butt welding flange welding installation requires flange welding on both sides. Therefore, the flat welding flange is generally used for low and medium pressure pipelines, and the butt welding flange is used for the connection of medium and high pressure pipelines.
3, Butt welding and flat welding flanges are the two most commonly used flanges, butt welding flanges are with neck, and flat welding flanges are not with. If it is best to use butt welding for safety considerations, if it is an ordinary medium, the pressure is not high, and the leakage will not cause danger, you can consider using flat welding flange.
4, Butt welding flange has the following advantages: health non-toxic, light weight, good heat resistance, corrosion resistance, heat insulation, good impact resistance, long service life, welding flange welding assembly is easier to set, installation is simple and convenient; The advantages of flat welding flange are widely used, can be used in metallurgy, machinery, chemical industry, petroleum, machine tools, water conservancy, construction, engineering, shipbuilding, environmental protection, coal, agricultural machinery, food, boiler pressure vessels and other industries; Beautiful appearance, flat welded flange surface is smooth, mainly used for carbon steel pipe connection.
