The thickness of integral flanges (such as on valves) is the same as weld neck in PNto PN1up to 600NB. Holes Hole Diameter Bolt Diameter Minimum Flange Thickness Cast Iron Ductile Iron Copper Alloy Steel. This diagram illustrated the arrangement but not necessarily the correct number of bolt holes. This type of flange has hardly changed.
Thus, a comparison is done only for this sealing surfaces. Due to the change of the designation of the sealing surface mistakes may occur occasionally.
Code 1flanges are supplied flat faced unless otherwise requested by the purchaser. For information sizes DNto DN1use PNdimensions. What is the meaning of pn16? Jinan Hyupshin Flanges Co.
Welding neck flanges Rated pressure 16. All dimensions are specified in mm. At higher temperature of 120°C to 300°C, it should be taken into consideration that the material yield point becomes lower.

As the new pressure ratings are slightly higher the flange thicknesses have slightly increased. Pressure grade from PN 2. Also the raised face dimensions (although rarely specifie flat face is mostly used) are slightly larger. Class 1and 3flanges is incluaed in the minimum flange thickness given above, but other raised faces must be added thereto.
Class 1loose flanges are thicker than integral flanges for sizes 31f,. Lengths of alloy steel stud bolts do not include the height of the points. Raised Faced - Also Mate with ANSI B16.
