Engineering FAQ
This chart lists equal tees by run NPS. Reducing tees require both run and branch sizes on the MTO.
Socket fittings weld to plain-end pipe prepared for socket fillet welds, not NPT threaded pipe ends.
Follow B16.11 class markings (e.g. 3000 lb) matching the line design pressure and temperature.
Forged crosses and lateral tees in A105 are available on inquiry per B16.11.
