ABSTRACT:
An improved fire protection system which incorporates delivery conduits having an inner liner, preferably formed of plastic. Attachment of the nozzle assemblies to the conduit is made at the flanged end of a piping segment and, preferably, at the connection points between two piping segments. The connection is formed so that water is communicated from within the conduits to the sprinkler head while avoiding contact with metal surfaces of the conduits. A spacer assembly is provided which is placed between the ends of two flanged piping segments. The spacer assembly includes an inner plastic disk and outer annular fire protection ring. A lateral port is disposed through both the ring and disk and preferably threaded for the attachment of a nozzle or other dispensing means. The spacer assembly forms a metal to metal seal with both piping segments for fire protection. Either lateral edge of the fire protection ring may be crimped or crushed slightly to aid in forming this seal.
