The diameter is 100 tubes and how much flange diameter and diameter are required
Note 1: in addition to the relevant standards, the Numbers behind the letter DN do not represent measurements and are not used for calculating purposes. Note 2: the standard of the DN identification system should be given the relation of the DN to the size of the pipe element, such as DN/OD or DN/ID.
The diameter of the pipe is not a specific size, the size of the pipe shall be measured according to the number of pipes. DN: the size of the letter and number of the elements of the piping system. DN and it consists of letters followed by dimensionless integer Numbers. The Numbers with end fittings aperture or outside diameter (mm) is directly related to the characteristics such as size.
Inside diameter of 114.3 mm; Diameter of 210 mm Name: steel flannel specification: DN100, but you best note the state label according to your pressure. Because the flange is thick and thin, and the number of bolt holes is different. Of the thick The nominal size of flanges does not represent the size of any flanges, only the specifications of the flange. The specific dimensions should be referenced by the flange standard. For example, DN100 doesn't mean that the diameter of the flange is 100 depending on the pressure of the flanges, the size of the standard.
