The design of Hanfalan in Shanxi Province is an inverse calculation process. According to the design method, the connection needs to be carried out through trial calculation. There are many design parameters that affect the final results, and their roles are intertwined.
The reasonable flange design aims at selecting a suitable pad(including material, type and size), fitting a suitable set of bolts(including material, specification, quantity and center straight diameter of bolts), determining a suitable flange material and its structural dimensions, And make them meet the strength requirements, so as to obtain a tight structure, reasonable force, seal reliable "connection." A large number of examples show that there is a large difference between the design of a reasonable Farland connection that satisfies the same design conditions and the usual design results. As far as the materials consumed by the flange and the manufacturing costs are concerned, the former can only be the latter. One of the points, At the same time, it has obvious economic benefits to Hanfalan's rational design and optimal design. It is a realistic work.
Over the years, people engaged in Frank's research and design work have constantly explored the rational design methods of flange connections, but in terms of the rational design of the entire flange connections, the work is more difficult. There are few reports on this aspect that are more comprehensive and mature. For this reason, people first turn to the need to start from the project. Simplify the optimal design of the entire flange connection, and propose a standard method to optimize the flange that can meet the requirements of the engineering design. Both consider that the optimal design of Hanfalan must involve the entire connection of the flange.
According to the use of Hanfalan, reasonable selection of gasket, flange material and bolt configuration, and full consideration of the design conditions, The optimal design of Hanfalan will be transformed into an active adjustment of the Hanfalan structure size(flange thickness, neck thickness A, neck height), so that the entire flange under certain design conditions, under the premise of meeting the strength requirements, The compact and lightweight structure is obtained from this perspective. At present, there are two types of optimized design for Hanfalan. One is the full stress standard method based on the Waters method. The other is the mathematical extreme method based on Hamadafalan analysis method.
