Flange pair

Flange pair is modeled same way as valve. Flange weight is considered the same as for a valve. Flange leakage check is automatically done when the "check leak resistance" flag is checked.

Properties

Property	Description
Name	Element name. If checked then it shown in 3D view
Length, H	Full flange pair assembly length
Weight	Flange pair assembly weight with bolts and nuts without insulation and product weight. Product and insulation weight are calculated automatically based on adjoining pipes.
Flange leakage check	Flange leakage check will be done if this option is selected
Leakage Check Method	Choose one of flange leakage check methods Insulation joint (Insulation Kit) stresses are checked according to manufacturers recommendations using 72% or 75% of yield stress allowable: Following equation for 72%: Following equation for 75%
Flange Code	Choose flange code: GOST, ASME B16.5, EN 1092-1
Gasket Effective Diameter, G	G - Diameter at location of gasket load reaction per ASME B 16.20 & ASME Sec. VIII Div. 1, Appendix 2, Table 2-5.2 For ASME B16.5, EN 1092-1 flanges G value should be calculated using following equations: OD – Outer diameter of gasket ID – Inner diameter of gasket b0 - Basic gasket seating width as given in Table 2-5.2 of ASME VIII Div. 1, Appendix 2 b – Basic gasket width Cb=0.5 for U.S. customary calculations, 2.5 for SI calculations
Nominal Pressure PN / Class	Nominal Pressure PN for GOST and EN 1092-1 flanges and Class for ASME B16.5 flanges
Material Group	Flange material group according to the selected code ASME B16.5-2020 EN 1092-1:2013
Factor Fm	Factor Fm used in Code Case 2901 (PVP) method according to following table
Bolt Area, Ab Bolt Circle Diameter, C
Bolt Material	Choose Material From database
