Piping Comparisons

Schedule against schedule, flange against flange, material against material — each comparison built on the published dimensions for both sides rather than on generalities.

Every table on these pages is generated from the same data as the specification pages. Where a figure is derived rather than tabulated — bore, weight, flow area, end load — the formula is stated alongside it.
