Theory to calculate the weight of large flange refers to

    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.

    Calculation method of theoretical weight

    Large flange (Tan Gang) theoretical formula:

     1.First (outer diameter and inner diameter) divided by 2 results.

     2.Then (outside diameter and the above results) X the above results X0.0246615X thickness

    After the above two steps, it studied the weight of large flange.

    For example: outer diameter 2600mm, inner diameter 2400mm,thickness of 50mm carbon steel large flange flange

   (2600-2400) /2=100mm

    (2600-100) x100x0.0246615x0.05=308.2688KG

     The weight is generally in the two decimal place four to five homes in.
