Abstract
A flange assembly comprises an annular mounting ring and a gate. The annular mounting ring is configured to be welded to the equipment and to connect an air cannon thereto. The mounting ring comprises threaded bolt holes and a slot and encircles a fluid passageway. The gate comprises a blocking portion that is frangibly connected to a flange portion. The gate is at least partially insertable through the slot such that the blocking portion is able to at least partially prevent fluid flow through the fluid passageway. The flange portion is configured to be securely attached to the annular mounting ring after the blocking portion of the gate has been frangibly disconnected from the flange portion.
