EAC.10 'SS{S. Smith}' EXHAUST PIPE.

We attach herewith a print of LeC.2524 shewing main connection for the above modified to a 4 bolt flange.

In making the original design we rejected the bolted flange in favour of the spherical union because we thought the faces of the former would never bed, and the pipes would be too stiff to allow the flanges to be drawn together.
