Go over section 8 Div 1, App. 2, which concerns flange design and goes over adequate bolt load for sealing.
At 275 psi, generally B7 bolts are suitable for a variety of flange and gasket combinations, especially for class 300 and above flanges, so I would look into off the shelf components to...
I'm trying to figure out the pressure and temperature ratings of AWWA C207 flanges. A standard like ASME B16.5 gives pressure and temperature ratings for material groupings, and I wanted similar ratings for AWWA flanges. However AWWA just gives a pressure rating, and then says "atmospheric...
Hello,
I'm looking at AWWA C207 flanges and I want to know the highest temperature appropriate for each class of flange and its given pressure rating.
Section 1.3.2.5 states "Pressure ratings are for conditions and temperatures customary in water utility service."
What are the highest...
I agree with C2it's answer with a caveat.
I would like to add that if you use Stainless Steel bolting with your stainless steel flange (a common scenario), the torque values in Table 1 of PCC-1 2010 won't be directly applicable. Those are based on Coefficients of Friction of 0.16 and 0.12...
Here's a fun question I'd like some feedback on.
It looks like in the attached photo, a water droplet was captured over the course of a 1/8 second exposure (5.6 aperture, 1/8 sec exposure from what the photographer told me). It looks like the drop fell into some water and this photograph shows...
