Abstract
A metering and pressure reduction piping system is prefabricated with backbone piping supported by a frame and a plurality of spool pieces that are interchanged at the site with selected metering and valve sections. The interchangeable piping sections having a common length and are connectable to the backbone piping via standardized interface flanges.
Claims29
A fluid metering and distribution piping system comprising:
- a frame;
- backbone piping supported by the frame, the backbone piping comprising connecting piping sections discretely disposed along a flow path from an inlet to an outlet;
- interchangeable piping sections attachable to the backbone piping between connecting piping sections on the flow path, comprising:
- a plurality of spool pieces,
- a flowrate metering section having a common length with at least one of the spool pieces, wherein the metering section is interchangeable with the at least one spool piece, and
- at least one pressure reducing valve section attachable to the backbone piping on the flow path downstream of the high pressure metering section and having a common length with at least another of the spool pieces, wherein the valve section is interchangeable with the at least another spool piece.

The piping system comprising:
- a frame comprising a bottom plate and an upstanding rack;
- backbone piping attached to the frame, comprising:
- an inlet connection,
- an outlet connection, and
- a plurality of connecting piping sections, interface flanges disposed at ends of the connecting piping sections;
- interchangeable piping sections attachable to the backbone piping, comprising:
