20150101698 | METHOD OF MANUFACTURING A FIELD JOINT COATING - A method of manufacturing a Field Joint Coating (FJC) for a pipeline, the method comprising: providing a pipe section to be joined to a similar pipe section or free end of a pipeline, wherein each pipe section is provided with a coating comprising a thermal insulation layer over a length of the pipe section having a protruding section, wherein the end zones of each pipe section are free of thermal insulation, thereby allowing access to the ends of the pipe section and the pipeline to connect the pipe section with the free end of the pipeline, applying an anti-corrosion coating layer on a connection region of the joined ends of the pipe section and the pipeline, heating the protruding section and applying an intermediate coating layer of a thermoplastic material on the anti-corrosion coating layer and the protruding section, applying a thermal insulation layer on the intermediate coating layer. | 04-16-2015 |
20150114510 | Encapsulated Insulation - This application describes insulated casings with cores of insulating material, coated with or otherwise encapsulated in a shell material are disclosed. A hinge may be fixed to first and second encapsulated cores and couple the first and second encapsulated cores to allow the insulated casings to removably cover a conduit. | 04-30-2015 |
20150362119 | FACED INSULATION PRODUCTS HAVING AN ASPHALT ADHESIVE - A composition and method for making a faced insulation product having an asphalt adhesive layer is provided. The faced insulation product includes a facing layer laminated to a fibrous insulation layer by a waterless asphalt adhesive. | 12-17-2015 |
20150376372 | RESIN COMPOSITION, MOLDED ARTICLE, MULTILAYERED PIPE AND METHOD FOR PRODUCING THE SAME - An object of the present invention is to provide a multilayered pipe having a layer comprising a resin composition containing EVOH, which is unlikely to exhibit the occurrence of cracking in the EVOH layer due to oxidative degeneration and has excellent gas barrier property even during long-term usage at high temperatures, and also to provide a resin composition for obtaining the multilayered pipe. The present invention relates to a resin composition containing 0.001 to 5 parts by mass of an antioxidant (B) and 0.00001 to 0.3 parts by mass of a conjugated polyene compound (C) having a molecular weight of 1000 or less, relative to 100 parts by mass of an ethylene-vinyl alcohol copolymer (A). | 12-31-2015 |

20160003380 | INSULATED FLOWPATH ASSEMBLY - A flowpath assembly has a first conduit defining a flowpath radially inward, and a second conduit spaced radially outward from the first conduit. A void defined between the first and second conduits contains an insulating material that may have a greater porosity than the first and second conduits. The assembly may be additive manufactured generally as one unitary piece with the raw material of the conduits being melted and solidified on a slice-by-slice basis and the insulating material being selectively bypassed by an energy gun of an additive manufacturing system. | 01-07-2016 |
20160003405 | SHEAR INCREASING SYSTEM - A piping system employs a friction layer of windings, beads or pellets placed between insulation layers and/or on the outermost layer, that being the insulation layer if no jacket is employed or the jacket if it is employed. The windings, beads or pellets are wrapped or applied while the layer is uncured or warm so as to embed themselves into the surface and create a uneven, bumpy or undulating surface. The resulting product increases friction both internally and externally to better restrain or inhibit pipe movement in underground, marine, or subsea applications or provide restraint to the surrounding environment (earth, concrete, etc.). | 01-07-2016 |
20160018047 | THERMALLY INSULATED CORRUGATED CONDUIT - The invention relates to a corrugated, thermally insulated conduit for fluids, e.g. for district heating networks, wherein at least one medium pipe (2) made of plastic or metal is surrounded by a thermal insulation layer (14), consisting of a polyurethane foam for example. The corrugation (25, 26) of the outer jacket (15) made of plastic is formed such that both the corrugation valleys (25) and the corrugation peaks (26) are round, particularly circular. In addition, the corrugation is dimensioned such that the corrugation depth T lies in a range of 4.5 mm to 8 mm for a conduit outer diameter range of 63 mm to 202 mm. This shaping and dimensioning of the conduit results in very good flexibility and thus the ability to roll up the pipe for the transport thereof. | 01-21-2016 |
20160018049 | HIGH TEMPERATURE INSULATED PIPELINES - An insulated high-temperature transport conduit for use in undersea environments. The conduit comprises a continuous steel pipe having at least a first layer of thermal insulation provided over its outer surface. The first layer of thermal insulation comprises a polymer composition having a thermal conductivity of less than about 0.40 W/mK and long-term heat resistance at continuous operating temperatures within the range from about 150° C. to above about 205° C. The first thermal insulation layer comprises a polymer composition comprising a polymer selected from the group consisting of one or more fluoropolymers, hydrogenated nitrile butadiene rubber (HNBR), and a blend of one or more fluoropolymers with HNBR. The conduit may further comprise second and third layers of insulation on top of the first layer, along with a corrosion protection coating underlying the first thermal insulation layer. | 01-21-2016 |
20160084140 | THERMALLY INSULATED COMPONENTS - A thermally insulated component comprising a structure having a heated interior and an exterior, and a thermal insulating structure for thermally insulating at least a portion of the exterior of the component structure. The thermal insulating structure comprises an aqueous mixture comprising an inorganic binder and inorganic filler particles, and a fabric comprising inorganic fibers. The fabric is impregnated with the aqueous mixture so as to form a pliable binder structure. The pliable binder structure is disposed completely around at least a portion of the component structure. It can be desirable for the component to further comprise at least one thermal insulator comprising inorganic fibers, where the thermal insulator is disposed between the pliable binder structure and the exterior of the component structure. | 03-24-2016 |
