Steel Pipe Flange ASME B16.5 A105 WN Flange ,2 lnch ,Class 300, Forged
Flange, from English Flange, also known as flange or flange. Basic meaning refers to the protruding structure on an object, or an object with a raised structure, such as flange bolts, flange shafts, etc. Because the flange structure is commonly used in connection between shaft and shaft, between pipe end and pipe end or between equipment and equipment, the flange generally refers to a part or structure used for connection in the mechanical field, such as pipe flange, reducer flange. Flange connection refers to the mechanical connection of gasket (ring) between flanges with several bolts. Often used for steel pipe, cast iron pipe, plastic pipe and other pipe sections that need to be removed frequently and larger pipe diameter pipe connection. [1] more broadly, connecting parts that rely on flange structures around two planes and use bolts to connect and close at the same time are generally referred to as "Frenchconnections ", such as ventilation ducts. This type of part can be called" flange parts ". Flange connection can realize sealing connection under large pressure, so it is often used for connection between pipes and fittings; flange connection can also realize the function of transmission, so it can also be used for connection between motor and reducer, or reducer and other equipment.
Neck butt welding flange
The butt welding flange with neck, also known as high neck flange and butt welding flange, is different from other flanges in that there is a long and inclined high neck from the flange to the flange, and the wall thickness of the high neck gradually transition to the wall thickness along the height direction, which improves the discontinuity of stress, because the strength of the flange is increased. The butt welding flange with neck is mainly used in harsh working conditions, such as pipe thermal expansion or other loads, which cause the flange to be subjected to greater stress, or repeated stress changes; pressure, temperature pipeline and high temperature, high pressure memory subzero low temperature pipeline.
