FLANGE
A flange is a crucial disc-shaped mechanical component essential for seamlessly connecting pipes, valves, and various equipment. Typically crafted from either metal forging or casting, it features precisely positioned bolt holes for secure fastening. Designed for use in pairs, a sealing gasket is ingeniously inserted in the middle to facilitate a detachable connection within pipeline systems. Flanges are widely implemented in pipeline projects across numerous industrial sectors, including petroleum, chemical industry, and electric power. Depending on the connection surface form, they are classified into different types such as flat welding flange, butt welding flange, and socket welding flange. They are indispensable key components within pressure pipeline systems.
The standout feature of a flange is its adherence to standardized connection dimensions combined with its exceptional sealing performance. Meticulously engineered, these parameters, such as pressure level and sealing surface form, comply with internationally recognized standards, ensuring seamless interchangeability of products from various manufacturers. High-quality flanges are precision-machined to guarantee the flawless flatness of the sealing surface, capable of withstanding a wide range of working conditions, from vacuum to high pressure, when paired with gaskets made from diverse materials.
In industrial applications, flange connections are integral to virtually all fluid transportation systems. High-strength butt welding flanges are employed in oil pipelines to secure safe long-distance transport. In chemical plants, corrosion-resistant flanges are the preferred choice to manage a range of chemical media, while in the food and pharmaceutical sectors, sanitary flanges are utilized to meet stringent cleanliness standards.
