Publication number: 20100037973Abstract: An efficient flexible hose construction is provided which incorporates resistance, when subjected to high negative pressure loads, to the collapse failure known “rollover” or “shingling”. The construction relates to a means of increasing the torsion capability of a flexible hose where the hose is formed from a helical wire that is coated and thereafter is connected to and supports a shroud or cover. Improved resistance to rollover lies in mechanical enhancements to the interface between the helical wire and the coating material, where the enhancement assists in maintaining the wire and coating as an integral unit and prevents separation leading to shingling under high vacuum pressures. The mechanical enhancement requires use of a specialized cross-section for the helical reinforcing wire.Type: ApplicationFiled: August 15, 2008Publication date: February 18, 2010Inventor: Stacy Smith

The textile tubing does not have to be stuck to large surface areas of the inner wall of a pipe due to its high burst pressure of more than 90 bar.Type: GrantFiled: February 28, 2002Date of Patent: January 21, 2003Assignee: Radlinger Maschinen-und Anlagenbau GmbHInventors: Josef Rädlinger, Horst Stimmelmayr, Frank Heinze, Frank-Michael Köpping

Patent number: 6497253Abstract: A flexible continuous hollow element configured as a jacket enclosing a hollow space for the transport of media includes a blocking layer (26) which is an integral part of the jacket (12). The blocking layer is impermeable to volatile molecules of the medium to be transported and is configured as a fabric layer (28) enclosing the interior space (14) formed by the layer (18) of the jacket (12).Type: GrantFiled: April 5, 2001Date of Patent: December 24, 2002Assignee: Aeroquip-Vickers International GmbHInventor: Silvia Enders

Publication number: 20020189697Abstract: A multilayer pipe which comprises at least an inner layer and an outer layer. The inner layer is made of extrudable plastic, such as polyethylene PE, cross-linked polyethylene PEX or polypropylene PP. The outer layer forms a fire-protecting layer and the matrix plastic of the outer layer is also made of extrudable plastic. A foaming agent, which does not react during the manufacture of the pipe, is mixed with the matrix. Further, the outer layer contains at least one additive in such a manner that the outer layer has a pipe-reinforcing component and a fire-retardant component. Most preferably, at least the outer layer is extruded by an extruder having a screw length ratio of less than 10 to its biggest diameter.Type: ApplicationFiled: June 6, 2002Publication date: December 19, 2002Inventor: Jyri Jarvenkyla

Publication number: 20020166595Abstract: This invention relates generally to the design and manufacture of high performance, composite, tubular structures. More specifically, the invention relates to a high performance, composite, tubular structure that utilizes an integral pattern of ribs on the internal diameter (“ID”) or outer diameter (“OD”) surface of the tube. The present invention provides high performance, composite, tubular structures that are both lighter and stiffer than conventional tubes. In general, the present invention incorporates unconventional features into the design of tubular structures, to greatly enhance performance. For example, in accordance with one preferred embodiment of the present invention, tubular structures are enhanced by incorporating small, stabilizing, raised ribs on the ID of the tubes.Type: ApplicationFiled: June 14, 2001Publication date: November 14, 2002Inventor: Howard A.

Publication number: 20020139430Abstract: A filament winding apparatus that efficiently fabricates an FRP pipe, which includes a helix layer and separated hoop layers. The apparatus winds fiber strands around a rotating mandrel and includes a winding unit moved reciprocally along an axial direction of the mandrel. The unit includes a helix winding head, which simultaneously winds fiber strands around the mandrel, a hoop winding head, which winds a fiber strand around the mandrel, a helix fiber spreading portion, which spreads the fiber strands wound around the wound subject by the helix winding head, and a hoop fiber spreading portion, which spreads the fiber strand wound around the mandrel by the hoop winding head.Type: ApplicationFiled: March 25, 2002Publication date: October 3, 2002Inventors: Masaaki Amano, Yoshiharu Yasui, Yasuki Miyashita

Patent number: 6453950Abstract: A round circular hose has a tendency to kink when extended. Also, a round circular hose can be difficult to form into a coil. With this background I have developed a hose with rigid sides to prevent kinking and for ease for forming into a coil provided with thicker wall sections.Type: GrantFiled: November 28, 2000Date of Patent: September 24, 2002Inventor: Donald Smith

Patent number: 6446674Abstract: An extruded multilayer plastic pipe is provided. The pipe comprises an inner layer, an outer layer and an intermediate layer. Each of the inner and outer layers is comprised of a thermoplastic material. The intermediate layer consists essentially of a lower density material than said inner and outer layers, and the intermediate layer is situated between and abuts both the inner layer and the outer layer. At least one of the inner, outer and intermediate layers consists of reinforced solid or foamed reprocessed plastic.Type: GrantFiled: April 27, 2000Date of Patent: September 10, 2002Assignee: Uponor Innovation ABInventors: Esko Hippeläinen, Kari Kirjavainen, Jyri Järvenkylä
