Patent number: 6840545Abstract: A welded flange connection and methods and apparatus for producing the connection are disclosed. A weld insert is disposed between the flared ends of abutted plastic pipe or plastic-lined pipe sections. The weld insert includes an annular support disc having a resistance heating element disposed at least about the inner circumference of the disc. When held tightly between the flared ends of abutted pipe sections power can be applied to the heating element to produce sufficient heat to temporarily raise the temperature of the adjacent surfaces of the flared sections of pipe above their melting point. When the weld is cooled, a strong, fluid-tight, thermoplastic weld is formed. A welded flange connection using the weld insert of the present invention effectively and efficiently produces high quality, fluid-tight connections in plastic pipe and plastic-lined piping systems.Type: GrantFiled: October 22, 2002Date of Patent: January 11, 2005Inventors: Bernd Schulte-Ladbeck, Oscar O. Jimenez

Patent number: 5713524Abstract: 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.Type: GrantFiled: December 21, 1995Date of Patent: February 3, 1998Assignee: Performance Plastics Products, Inc.Inventors: Wallace Greene, Bernd Schulte-Ladbeck

Patent number: 5277455Abstract: Methods and apparatus for improved containment, detection, and monitoring of leaks of piped substances in which piping systems are constructed of connections of flanged, plastic-lined concentric pipe segments, these segments each having an inner and outer shell with an annulus therebetween and an aperture connecting the annulus with the exterior flange face of the pipe segment. A connector is described which may be placed between pipe segments to be connected and which has annular resilient sealing members and inner plastic seals to provide seals at the connection. The piping system provides an annular containment passageway to capture fluid escaping from the inner shell of a pipe segment and communicate the fluid to a fluid detection port in the connector. The annular containment passageway comprises at least one pipe segment annulus, at least one aperture in the pipe segment, and an annular fluid opening at the connector to communicate fluid toward the fluid detection port.Type: GrantFiled: September 25, 1992Date of Patent: January 11, 1994Assignee: Performance Plastics Products, Inc.Inventors: Gail W. Graves, Bernd Schulte-Ladbeck

Patent number: 5199153Abstract: A method of making a flanged pipe length includes flaring a metal pipe by rotating a grooved tool about the inside of the pipe and introducing a plastic tubular sleeve into the pipe. The tubular sleeve is subsequently heated and forced against the flanged portion of the metal pipe whereby the plastic material assumes a shape complementing the projections formed by the grooved tool.Type: GrantFiled: December 2, 1991Date of Patent: April 6, 1993Assignee: Compagnie Plastic OmniumInventor: Bernd Schulte-Ladbeck
