JIS 63K Flange
A high neck flange, also known as a long neck flange or a neck flange, is a disc-shaped component mainly used to connect pipes. Currently, it has been widely used in fields such as petrochemical, urban water supply, and power systems. Especially in recent years, with the planning and construction of the ultra-high voltage transmission line project of the State Grid of China, the demand for ultra-high voltage steel pipe towers has sharply increased. The high neck flange, as a new form of flange connection of steel tube tower, has been proved to be progressiveness and reliable, which plays a vital role in improving the production capacity and product quality of steel tube tower.
Advantages of high neck flanges
The high neck flange, due to its overall shape and high neck height, greatly improves the stiffness and load-bearing capacity of the flange. Suitable for assembly lines and automated production, the production efficiency of component assembly and welding processes has been greatly improved. The insertion form of relatively flat flange and steel pipe reduces the consumption of welding materials, greatly reduces the welding workload and Labor burden, reduces the welding stress, and the structure is not easy to deform. In addition, the high neck flange is easy to install on site, which can omit the process of preventing the weld from being bruised. It is more popular.
