Vulcan Offshore Tip #21: Pipecap Dimensions

In addition to the cushion block size, another important input to the wave equation analysis is the size of the pipe cap (or anvil) block. Below are the basic dimensions for the pipe caps along with the depth of the steps.

HAMMER SIZE	A	B^DIA.	C	D	E	F°	G^R.

All dimensions in inches unless otherwise noted.

Note: Tip dated 1 September 1980. Subsequent to this Vulcan introduced its line of "Light Weight High Strength" pipe caps. The dimensions such as "A" were reduced and others such as "F" and "G" were eliminated altogether. It is important to determine whether the pipe cap being looked at conforms to the above dimensions or not. Also, many of Vulcan's customers manufactured their own pipe caps, which may or may not conform to the dimensions shown in this tip.
