The production process of large flange

      Large flange refers to the flange exceeds the relevant departments of the state specified size. Generally refers to the flange size above DN2000. This product is full of welding products, no screw thread,are often used to DN15-DN100 specifications. The nationalstandard flange GB/T9119-2010 0.25MPa to full size, standard 1.6Mpa is DN2000. The 2.5MPa standard is the greatest pressurein the DN800. Making such flanges are to make constructiondrawings to production. Production process of forging and rolling and splicing three. Product size is too large can only be in process of rolling and splicing.

Product process

       The first plate cut into the appropriate note, note the lengthaccording to the large flange specifications. Then roll ring machinerolled into a circle, electrode the interface of firm welding, weld for the X spectrum test. And then press the pressing, processing line,chamfering process by lathe processing, finally pierce bolt holes by the indexing disc with drilling machine. 

       When a. When a bolt is not the bolt hole on a large flange weld areas.

Rolling flange forging of lower cost than. But some large flangeforging does not come out. The number of such products is the use of theoretical weight to weight, in the calculation, is not thewaterline, stop, bolt hole chamfering, weight lose. 

      Flat productprices low, but if a large flange processing dovetail groove likeprocesses or thickness thin price will be higher. The reason is acomplex processing technology and thin and thick spends theprocedure is the same. Theoretical weight is according to the following formula to calculate the.
