The user needs to select suitable flanges based on pressure temperature ratings. The user may use our Flange ratings calculator for that. 7) The Program is based on ASME B31.3 Code - 2018 Ed. 8) If you notice any error, please let us know, so that can be rectified.
I am looking for some calculation or information for stiffening of Blind plates for Hydrotest. The Plates avaialable aren't sufficient for the hydrotest pressure. The diameter of the pipe is 54". the wall thickness of the Pipe is 12mm. I tried calculating the required thickness as per the Sec VIII Divn 1 code. The article shows the ASME B16.5 dimensions of Blind Flanges Classes from 150 to 2500 (NPS, ID, OD, Thickness, and bolting details, tolerances) – in millimeters. I'm trying to figure out the minumum thickness of a 36" blind flange. I'm making a crud trap with some big HDPE pipe, and am going to use 2 blind flanges on the ends. I found a formula in Perry's: t = d(3P/16S)^0.5 where d=inside diameter, P=internal pressure, S=allowable stress, and t=thickness
How can you calculate the thickness of a blind flange? The thickness of a blind flange can be calculated using the ASME B16.5 standard equation. This equation considers various factors including the pitch circle diameter, internal pressure, and allowable stress to determine the minimum required thickness. The application is to insert a flange skillet temporarily on two ends to hydrostatic test a 24 line. I am using the equation found in ASME 304.5.3 for determing . Skillet Flange for Hydro testing ASME 31.3 - Skillet Flange for Hydro testing . much the test will dish out the blind. If you can get a 1" blind in (with a 1/8" gasket also) then .ASME VIII-1 Appendix 2 provides a method of sizing flanges.

A specification for steel forgings such as ASTM A694 covers a wide range of strength grades from F42, with a minimum specified yield strength of 290 MPa, to F70, with a minimum specified yield strength of 485 MPa. The compositional limits are given in ASTM A694 (product analysis) are ≤0.3% carbon 0.13-0.37% silicon and ≤1.50%.Code Comparison is made against ASME Boiler and Pressure Vessel Codes, Pressure piping, and API standard practices taking Service, Code reference, Minimum Hydrostatic test calculation, Maximum permissible test pressure, Minimum test hold time, pressure gage, test temperature limits into consideration. Apart from this, there are many factors .Blind flanges have the face thickness of a flange, a matching face type, and similar bolting pattern. . they may not meet Code design calculations.

Three hydro-test parameters are: the hydrostatic test pressure, ratio of hydrostatic test pressure to actual operating pressure, and the pipe’s estimated hoop-stress during test. These should be calculated and recorded as follows: Hydro-test Pressure = _____-psi (approved by Authorizing Agent(s)) EQ-1 History reports noted that the spacing between flanges was to thin to meet ASME B31.3 blank calculations for thickness. The pipe is 26" carbon steel and will be tested at 90psig at 80degF with water. Allowable stress of a A-105 blind is 23.3ksi, but is it possible to use the tensile or yield stresses since deformation of the blind is acceptable .Temporary Blind Flange Thickness Calculation For Hydrostatic Test International Code Council Lightning Protection of Aircraft Franklin Fisher,J.
