Market forecast of large diameter carbon steel flanges
Source :admin   Time:7/9/2018 9:57:54 PM   hit:

  There are holes in the ANSI B16.5 Calss 300 Carbon Steel Forged Slip on Flange, which can be stud to make the two slip on flanges tightly connected and the flanges are sealed with a gasket. When the size of the slip on flange is determined by the slip on flange standard, the nominal diameter and nominal pressure of the flange must be known. There are holes in the carbon steel flange, the bolt can be worn, the two flanges are tightly connected, and the flange is sealed with the gasket.

  Flange standards determine flange size, we must know the nominal diameter of flange and nominal pressure. The nominal diameter of the slip on flange of the pressure vessel is the same as the nominal diameter of the pressure vessel. For example, pressure vessels of DN1000mm should be fitted with DN2000mm large caliber flange.

  The determination of nominal pressure of flange is related to the maximum operating pressure of flange, operating temperature and flange material. Because the flange size series and flange thickness are calculated according to the mechanical properties of 20MnR at 250 C. So the size of the flange determined by this datum is specified. The maximum allowable operating pressure at 200 degrees is considered to be the nominal pressure of the flange.
