2024年4月4日 · Here you can find the calculation of the minimum blind flange wall thickness based on internal design pressure and design temperature for bolted and circular blind flange, per ASME B31.3 and ASME Section VIII, Division 1, UG-34.

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.

2023年5月31日 · This online calculator allows the user to calculate spade/blank thicknesses for Class 150 RF/FF flanges from sizes DN15 to DN1500 using flat ring gaskets for B16.5 and B16.47 Series A Flanges for a range of materials, pressure temperature combinations and custom corrosion allowances.

2022年10月11日 · The thickness of a blind flange used depends upon the pressure and the pipe diameter and can be estimated from the equation given in ASME B31.3, T m = d g (3P/16SE) 0.5 + C where

Testing( Hydrostatic & Pneumatic )-Blind plate & Blank Thickness calculation Chart and Formula 1.The piping diameter is 1½” and above, the following table shall be followed for the thickness of blind plate

2018年5月30日 · In order to use as thin as possible blind flange, and to ensure that the blind flange does not deform in the process of use, we do stress analysis on the stress of blind flange, and give the calculation method of blind flange thickness with examples. The calculation result is the thinnest thickness of the blind flange.

2021年2月23日 · For example: add blind flange on DN200, PN16 and normal temperature pipe flange, single side pressure P = 0.686mpa, steel plate material 20g, calculate blind flange specification. According to the table, the sealing surface diameter of DN200 and PN16 pipe flange is 268mm, and the yield limit of 20g steel plate is 245MPa.

2008年2月23日 · To find the thickness of spectacle blind, you have to define the NPS of pipeline and class (or rating) of its flange. Then from Table 1 of ASME B16.48-2005 Line Blanks you can easily find all dimensions of spectacle blind including its thickness. The attached table represents the dimensions of class 150 raised face figure 8 blanks.

The minimum required thickness of flat unstayed circular heads, covers and blind flanges attached by bolts causing an edge moment in which case the thickness shall be calculated by the following formula:

This document provides calculations to determine the minimum required thickness of a blank according to ASME-B-31.3 code. It lists the variables and values used in the thickness calculation formula and shows the worked out calculation to get a required thickness of 114.68 mm.
