| 20080271805 | Fluid Conduit with Layered and Partial Covering Material Thereon - A fluid conduit with layered and partial covering material thereon. The fluid conduit may be of many forms and types and attached thereto and configured thereon covering material, in partial form and a selected number of layers. The covering of fluid conduit/conductors resulting in the creation of a novel and very effective, in functionality, of a fluid conduit/conductive system, such as a septic pipe of smooth wall, of corrugated form, of any form of cross sectional configuration including circular, elliptical, rectangular, triangular or any other geometric shape any of which will and can provide for the flow of a fluid of forms such as septic flow fluid and the like. Included herein as a part of the invention is fluid conduits produced by the means and methods of this invention. Substantially, the fluid conduit system having incorporated therein and thereon the form and layers of covering created as a consequence of the means and method of configuring such conduit included as a feature of the invention. Used herein is a multilayer fabric of varying deniers for the processing and treatment of fluids which must be treated to remove materials so that the resultant treated fluid may be reused and/or returned to the earth and particularly to the water table. More particularly the multilayer fabric, each layer being of selected denier, is used in combination with conduit in a drainage field or leaching system usually associated with a septic tank or septic system. Most particularly the multilayer fabric of varying deniers is wrapped around corrugated plastic pipe of the type well known in the field of drainage or leaching fields. At least one of the multilayer fabric layers is formed from an unstructured assemblage of fibers. The unstructured assemblage of fibers are supported by an outer sheeting however it could be made of a grid mesh or additional material choices which in effect will provide for separation between layers. The unstructured assemblage of fibers provides a large surface area whereon consequent biodegradation of the oils, greases and chemicals takes place permitting treated fluid to pass omnidirectionally through the unstructured assemblage of fibers and subsequently leach into the ground. The system generates bacteria more quickly and thereby causing the system performance to be enhanced in quality of performance and in the speed of performance—speed of performance was increased over prior art methods by a substantial of amount. | 11-06-2008 |
| 20080283139 | Flexible Pipe and Method for Manufacturing the Same - A flexible pipe ( | 11-20-2008 |
| 20090114304 | FLEXIBLE PIPE - The formation of a resin layer, a metal layer and an insulating resin layer on an outer surface of a corrugated metal pipe for flowing a fluid provides a flexible pipe, whose corrugated metal pipe does not suffer from having apertures even with spark discharge by induced lightning. | 05-07-2009 |
| 20100059134 | FLEXIBLE PIPE - The invention relates to a flexible pipe for transportation of fluids and gasses, e.g. useful in water transportation, and in offshore transportation of crude oil e.g. from seabed to an installation or between installations. The flexible pipe of the invention comprises a new type of armouring layers which is made from a combination of one or more profiled wires and one or more metal strips. A folded strip is an endless unit with at least one fold and a width which in unfolded condition is at least 6 times its thickness, such as at least 10, such as at least 15, such as at least 25 times its thickness or even up to 100 or 500 times its thickness. A profile is a preshaped non-folded cross sectional profile. The profile may preferably have a width of less than 6 times its thickness. The term ‘endless’ is used to indicate that the tapes and profiles are very long compared to their other dimensions. | 03-11-2010 |
| 20110120583 | PIPE WITH SHEATH HAVING REDUCED PERMEABILITY TO ACID COMPOUNDS - The pipe is intended for carrying a petroleum effluent comprising at least one of the acid compounds CO | 05-26-2011 |
| 20110232798 | FLEXIBLE UNBONDED PIPE AND A METHOD FOR PRODUCING SUCH PIPE - The present invention relates to a flexible unbonded pipe comprising an inner liner capable of forming a barrier against outflow of a fluid which is conveyed through the pipe, and one or more armouring layers on the outer side of the inner liner. The flexible unbonded pipe comprises at least one polymer layer and at least one film layer, said polymer layer being bonded to said film layer via one or more bondings selected from the group of chemical bondings and physical bondings. The film layer may preferably be a metal film layer, such as aluminum film, stainless steel film or duplex film. The polymer layer may preferably be cross-linked polyethylene. The interfacial bonding between the polymer layer and the film layer should preferably be sufficiently strong to prevent creation of gas pockets between the layers when subjected to an increased pressure of aggressive fluids (hydrogen sulphides, methane and carbon dioxide) on the film side of the pipe. Thereby it is possible to protect armour layer(s) from aggressive fluids. | 09-29-2011 |
| 20120261019 | UNBONDED, FLEXIBLE PIPE - The invention relates to an unbonded, flexible pipe having a length and comprising a tubular inner sealing sheath, at least one metal armor layer and an outer sealing sheath. The unbonded, flexible pipe comprises at least one insulated length section comprising a fluid permeable thermally insulating cover surrounding the outer sealing sheath in the insulated length section. The thermally insulating cover is further surrounded by a liquid permeable jacket, and preferably the thermally insulating cover is liquid permeable. | 10-18-2012 |
| 20130255819 | GAS TUBE STRUCTURE - A gas tube structure includes a flexible tube. The end of the flexible tube is connected with a fixed connector. A sleeve is fitted on the fixed connector. The fixed connector and the sleeve are connected to a movable connector. The fixed connector has a connection section extending from an outer end thereof. The connection section has an annular seal groove and an annular buckle groove thereon. The sleeve has a sleeve hole therein, a stop flange at one end thereof and an engaging groove formed on in inner wall thereof. One end of the movable connector has a receiving hole and a C-shaped groove formed on an outer wall of the receiving hole. The C-shaped groove is adapted to receive a C-shaped buckle. The present invention has a stable connection, is safe for use, can lower the cost and enhances assembly efficiency. | 10-03-2013 |
| 20140366979 | Plastic Hose with Antistatic/Dissipative Properties - A plastic hose with antistatic properties, comprising: a hose wall of plastic and a reinforcement of plastic, wherein the reinforcement has a higher stiffness than the hose wall. The equalizing of charge concentrations within the hose and the conduction of electrical charges away from the hose is to be ensured by means of an inner layer of an antistatic/dissipative or electrically conducting plastic. | 12-18-2014 |
