Very large blind flanges
Very large blind flanges
(OP)
a condenser cooling water system with 5100mm diameter pipe has a 2000mm drain connection which is guided upwards and need to be closed with a blind flange. The Flange thickness for the blind as per UG34, SecVII,Div1, equation 2.5,1 works out to about 114mm. Are there codal provisions whereby I can use a thinner Blind flange (say 60 to 70mm) with reinforcing beams? What are the calculations for sizing and spacing the beams?





RE: Very large blind flanges
What is your design pressure and proposed materials of construction ?
What is the configuration, pressure rating and code construction for the mating flange ?
How much deflection is permisible at the center of the flange ?
What are "codal provisions" ?
Consider a simplified "Roark" type circular plate calculation .... IMHO, a simplified analysis is appropriate for a CCW system.
