STAND PIPES, PADS ETC.
Pressed Plate Saddles
Where pressed plate saddles are employed they shall be formed
to bed closely to the boiler, and machined on the face jointing
the mounting and on the edges. The studs for attachment of mountings
if screwed through the saddle, shall each be fitted with a nut
on the inside having a thickness equal to the diameter of the
stud. Where the stud holes do not penetrate through the saddle,
the length of the screwed portion of the stud in the plate shall
not be less than the diameter of the stud.
