Forged Steel Fittings
In accordance with ASME standard B16.11 - “Forged Fittings,
Socket-Welding and Threaded” this table shows the schedule of
pipe corresponding to each class of ftting for rating purposes.

Materials
The steel for Anvil Forged Carbon Steel Fittings consists of forging, bars, seamless pipe
or tubes which conform to the requirements for melting process, chemical composition
and mechanical properties of ASTM A105.

Reducing Fittings
Reducing elbows, tees and crosses are available in both threaded
and socket-welding.
On reducing tees and crosses give the size of the largest run
opening; then give the opposite opening. On a tee give the
branch size last. On a cross give the largest side outlet third and
the opposite opening last.
ASME B16.11 provides that the maximum allowable pressure of
a ftting be computed in accordance with the applicable piping
code or regulation for straight seamless pipe or for material of
equivalent composition andmechanical properties to the ftting.
Any corrosion or mechanical allowances and any reduction in
allowable stress due to temperature or other service conditions
must be applied to the pipe and ftting alike.
