Our factory production of wind tower is to use forged flange (and specification is written in the continuous casting slab is not allowed), incoming raw materials warranty flange is written in continuous delivery, that is not the flange casting forging? Are you in a hurry to accept the goods?! I have less money, thanks in spirit, please knowledgeable people teach in, with little to say, it is best to have some basis for what? Thanks a million!
Now the steel raw materials are mainly ingot and billet, steel materials in the factory are indicated in the warranty on this; and casting or forging flanges and not directly related to see through what kind of flange is processed out of the process if it is casting, casting products. If it is after forging, is forging products, suppliers should be issued by the product warranty, product warranty can be seen by casting or forging. Technical specifications written is not allowed to use continuous casting slab, and if the product for the use of steel raw materials, then even forging products are not qualified, and I hope to help you.
Forged flanges and cast flanges use different levels of stress, and forged flanges can be used in high and low pressure pipelines,Casting flanges can only be used for non pressure lines, otherwise leakage is very easy.Hebei bend flange, my name is Liu Jiangong.Flange production using continuous casting does not mean that the flange is casting, can only say that raw materials are not up to standard. Let's pay for the goods. High pressure pipe, as far as possible the use of round steel material.
Casting and forging flange flange is not the same, is the use of steel or steel forged flange through blanking - heating - forging - lathe - - - - type oil packing factory etc.,Casting flange is the use of iron, iron grinding electric furnace melts, the molten iron is poured into a mold, cooling, processing, and some extra processing procedures, is that, molten iron is poured into a mold, molding after heating in forging a processing form.
