Butt Caps used as Heads

Butt Caps used as Heads

Butt Caps used as Heads

(OP)
I want to use Butt caps for the heads of a 6" diameter tank. Which head type would one use in Compress for the calculation of a butt cap?

Thanks in Advance.

RE: Butt Caps used as Heads

I'm not familiar with the term "butt cap" but if you are talking about a "pipe cap" use a 2:1 elliptical with the appropriate length stratight flange.

grumpiefool,

I believe Compress does not do calculations for standard pipe fittings. You can model your pipe cap as a 2:1 SE head to graphically show it; but I would not rely on Compress' calculation output for that particular component.

If your vessel code is ASME VIII-1 and your pipe cap is an ASME B16.9 fitting, refer to UG-44.

RE: Butt Caps used as Heads

I model pipe caps as 2:1 elliptical heads. You do have to keep in mind that the pipe caps have a 12-1/2% pipe tolerance though.

RE: Butt Caps used as Heads

Be very careful in your documentation of this calculation.  Should an ASME team leader find a pipe cap calculated as an ellipsoidal head during a review you will get some grief.  UG-44 is quite specific as to how it is calculated.
