| Structural Features | Butt-welding flanges are usually composed of a flange disc, a neck, and a welding groove. The necked structure can increase the strength and stability of the connection between the flange and the pipeline, and reduce the concentration of welding stress. The design of its welding groove is convenient for butt-welding connection with the pipeline, which can ensure the tightness and strength of the connection. |
| Working Principle | By performing butt welding between the welding groove of the flange and the end of the pipeline, a firm connection is formed. In the pipeline system, the bolt holes on the flange disc are used for installing bolts. By tightening the bolts, the two flanges are closely connected together, thus achieving a sealed connection between the pipelines and bearing the pressure and temperature of the medium inside the pipelines. |
| Application Scenarios | It is widely used in the pipeline systems of industrial fields such as petroleum, chemical industry, natural gas, electric power, metallurgy, pharmaceuticals, and food. It is especially suitable for the pipeline connection of media such as high-temperature, high-pressure, flammable, explosive, toxic, and harmful substances, which can ensure the safe and reliable operation of the pipeline system. For example, butt-welding flanges are widely used in the process pipelines of petrochemical plants, the steam pipelines of power plants, and other situations. |
| Advantages | |
| High strength | Due to the adoption of butt-welding connection, the welding quality is high, and it can withstand relatively high pressure and tensile force, ensuring the safe operation of the pipeline system. |
| Good sealing performance | With the appropriate form of sealing surface and gaskets, a good sealing effect can be achieved to prevent the leakage of the medium. |
| Corrosion resistance | According to different usage environments, butt-welding flanges made of different materials can be selected, such as stainless steel, alloy steel, etc. They have good corrosion resistance and are suitable for pipelines transporting various corrosive media |
| Convenient installation | Compared with other connection methods, the installation of butt-welding flanges is relatively convenient. It only requires welding the flange to the pipeline and fixing it through bolt connection. |
