90 Degree Elbows Lined Piping, ASME Fittings

All our standard elbows are manufactured according to ASME B16.5  and wherever possible lined in HiPerFlon PFA with an investment cast steel body to provide the permeation and wettability benefits that this superior lining material brings, coupled with the geometrical accuracy that can be critical in many applications. The use of PFA also brings increased vacuum performance which can be useful on larger sized lines.

Where it is not appropriate to line the elbows in PFA such as with rotating flanges and non-standard dimensions, these are lined in HiPerFlon PTFE as are static-dissipating elbows.

As with all our fittings, flanges are supplied as fixed as standard but we also supply fixed / rotating flanges and fittings with flanges rotating.

The dimensions below are to suit B16.5 Class 150 piping systems.
