ASTM A105 Flange

Home > ASTM A105 Flange

Why ASTM A105 flange is a most popular grade among others?

ASTM A105 Flange is an American Standard for forged carbon steel forging
A105 flange material is similar to C22.8 Carbon Steel
SA 105 Flange can produced in various connections such as Blind, Slip on, Socket weld, Weld neck etc. at lowest price

ASTM A105 Carbon Steel Pipe Flanges Application

Calculate A105 blind flange thickness for hydrostatic testing

t = d *(CP/SE+1.9W hg/SE*d^3) ½

Where,

d= A105 flange diameter or short span
E= Joint efficiency
S= Maximum allowable stress value
W= Total bolt load
hg= Gasket moment arm
P = Design pressure
C = 0.3 From Fig UG-34(j)

So, here are few results using above formula

Requirement of A105 nace flange testing

Tension tests
Hardness tests
Hydrostatic tests (as per S57 in A961/A961M)
Macroetch test
Magnetic particle examination
For surface – Liquid penetrant examination

A105n carbon steel flange heat treatment

It should be done between 137 to 187HB Hardenss
