ABSTRACT:
A gas riser apparatus having an O-ring sealing arrangement according to the present invention provides improved sealing between an inner pipe and an outer pipe of the riser apparatus. The riser apparatus includes an inner plastic pipe having one or more grooves for receiving resilient sealing members. A plurality of O-rings are disposed within one annular groove and an outer metal pipe is telescoped over the plastic pipe. An annular crimp extends around the outer metal pipe at a location of the plurality of O-rings and forms a seal between an inner surface of the metal pipe and an exterior of the plastic pipe by compressing the O-rings. This O-ring seal configuration provides substantially improved low temperature sealing.
