ABSTRACT:
Ground level gas meter risers for plastic service lines in which the riser is a one-piece assembly for transition from underground plastic to above ground steel gas service lines. The riser assembly includes a mounting section of pipe connected to a plastic transition fitting. The plastic fitting in turn receives the plastic tube gas carrier. A steel casing or jacket extends from the plastic fitting around the plastic gas carrier tube for a predetermined distance to a sealing device. An upper protective steel casing interconnects the mounting pipe and the upper end of the lower protective casing. A relatively thin epoxy or plastic coating extends from under the seal device at the lower end of the riser to above the upper casing.
