Abstract
Disclosed is an improved assembly of orifice chambers for reducing pressure of large gas flows effective to reduce noise of the gas flows and wear on orifice chambers by progressive pressure drops in the gas flows through successive orifice plates which are releasably secured, preferably by fillet welding, in each of the orifice chambers, removal of one or more orifice plates in an orifice chamber providing manway access to the next succeeding orifice chamber for inspection, repairs, and replacement of the orifice plates thereby reducing the manway opening or access to only one orifice chamber and eliminating separate access manways or manholes for each of the orifice chamber necessary for maintenance of the orifice chambers. Preferably, an internal shell providing an annular space with the body to which the orifice plates are connected is connected to the body by an annular ring and brace by fillet welding in compressions.
