138144000 | Spirally wound layer | 9 |
20090260706 | Pipeline For Conducting Air For Air Conditioning In Aircrafts - The invention relates to a pipeline | 10-22-2009 |
20100071798 | MONOLITHIC CERAMIC LINED FIBER GLASS PIPING AND FITTINGS - A method is provided involving manufacturing a solid monolithic hollow ceramic liner, such as a cylinder, reducing cone and bend and then wrapping the solid monolithic hollow ceramic liner with a fiber glass resin. This forms an external housing for the mold and flange connections can be fixed on either end to facilitate its connection to valves, pumps and other piping systems. | 03-25-2010 |

20130248043 | STRUCTURAL TUBE COMPRISING A FIBRE REINFORCED POLYMER - There is provided a structural tube ( | 09-26-2013 |
20130276932 | SYSTEM AND METHOD FOR REINFORCING COMPOSITE PIPES - A process for manufacturing pipes using thermoplastic pipe and “tape” (continuous fiber, fully wetted in a similar thermoplastic as the pipe) that embeds the fibers into pipe surface. In one embodiment, an ambient temperature tape is wrapped around the cold pipe in a dry environment. An external heat source is used to heat up the pipe causing the thermoplastic to melt and the pipe to expand due to thermal expansion. Since the fibers have less stretch than the thermal expansion of the pipe the fibers will be embedded into the molten layer of the pipe, creating a permanent bond between the fibers and the pipe. A protective film is applied to the pipe. Portions of the tape and film are scraped from the surface of the pipe creating an area where the end of the pipe is coupled to another pipe using an electronic fusion coupler. | 10-24-2013 |
20130291991 | Pipe Section Having Polyarylene Sulfide Composition Barrier Layer - Pipe sections and methods for forming pipe sections are disclosed. A pipe section includes a hollow body, the hollow body having an inner surface and an outer surface, the inner surface defining an interior. The pipe section further includes a barrier layer surrounding the hollow body, the barrier layer having an inner surface and an outer surface. The barrier layer is formed from a polyarylene sulfide composition. The polyarylene sulfide composition includes a polyarylene sulfide and a crosslinked impact modifier. Such pipe sections exhibit high strength characteristics and flexibility as well as resistance to degradation, even in extreme temperature environments, while maintaining desirable processing characteristics. | 11-07-2013 |
20130319571 | COMPOSITE PIPE - A composite pipe and method of manufacture comprises an inner core made of a resinous material, a prepreg material helically wound about the inner core and an outer shell covering the wound prepreg materials. The materials are applied at preselected melt temperatures to assure coherence among the materials and preclusion of voids and/or annuli therebetween. A cooling of the inner pipe core during initial application of the tape layer of prepreg materials stabilizes the radial configuration of the pipe core during tape wrapping and thus the appearance of undesirable voids and/or annuli in the composite pipe mass. | 12-05-2013 |
20140124081 | SPIRALLY WAVED SYNTHETIC RESIN CONDUIT WITH COUPLING, AND CONNECTION STRUCTURE FOR SPIRALLY WAVED SYNTHETIC RESIN CONDUIT - A spirally waved synthetic resin conduit has a coupling and a connection structure, and is configured with a small number of components, achieving sufficient water and pressure resistances, excellent sealing properties with no need for any rigid material or high accuracy, reduction in weight and cost, and easy handling with facilitated connection work on site. The spirally waved synthetic resin conduit, provided with a coupling, includes a receiver opening provided at an end of the conduit and connected to another spirally waved synthetic resin conduit. The receiver opening is formed with a foamable resin into a cylindrical shape so as to extend from the end of the spirally waved synthetic resin conduit in an axial direction of the conduit, and an FRP layer is formed by impregnating reinforcing fibers with a resin, at least on an outer peripheral surface of the formed receiver opening at a connection end. | 05-08-2014 |
20160109040 | Pipe Section having Polyarylene Sulfide Composition Barrier Layer - Pipe sections and methods for forming pipe sections are disclosed. A pipe section includes a hollow body, the hollow body having an inner surface and an outer surface, the inner surface defining an interior. The pipe section further includes a barrier layer surrounding the hollow body, the barrier layer having an inner surface and an outer surface. The barrier layer is formed from a polyarylene sulfide composition. The polyarylene sulfide composition includes a polyarylene sulfide and a crosslinked impact modifier. Such pipe sections exhibit high strength characteristics and flexibility as well as resistance to degradation, even in extreme temperature environments, while maintaining desirable processing characteristics. | 04-21-2016 |
