An air-induction system of an engine includes a hose assembly. The hose assembly includes an elastomeric hose having a circular cross section when in a natural state, and a deformable sleeve received around the hose and configured to create an indentation in the hose for part clearance. The sleeve has an end section having a circular cross section and an intermediate section in which the sleeve projects radially inward into a sidewall of the hose such that the hose is deformed from the natural state to a deformed state in which the sidewall is deformed radially inward creating the indention and a non-circular cross section of the hose at the intermediate section.

The purpose of the present invention is to provide a heat insulating structure, a heat insulating body, a method for manufacturing a heat insulating structure, and a method for manufacturing a heat insulating body that can substantially reduce a manufacturing cost and a manufacturing time. A heat insulating structure is provided with: a plurality of partition members that are reticulately provided in a space region between one wall part and another wall part opposed to the one wall part and partition the space region into a plurality of partition spaces from the side of the other wall part to the side of the one wall part; and a plurality of fraction members that are provided to support the one wall part and fractionize partition spaces facing the one wall part among the plurality of partition spaces so as to be gradually smaller toward the side of the one wall part.

A concentric, multi-layer laminated wrap for protection of plastic pipes including up to 60-minute fire endurance, low flame spread, low smoke, and toxic products of combustion. The laminated wrap can withstand temperatures up to 2000° F. for up to a period of 60 minutes. The concentric laminated wrap includes an inner support layer that provides strength, an intermediate fire protective coating layer that provides fire, heat, and high temperature protection, and an outer top coating layer that provides resistance to abrasion, impact, and environmental factors including water, salt water, hydrocarbons, chemicals, and gases. The protection to plastic pipes and pipe appliances is provided by the fire protective coating layer that is applied directly to the pipe or as a layer in the laminated wrap around the pipe. The present invention is disclosed for fire, heat, and high temperature protection of pipes, including linear pipes and pipe appliances such as flanges, couplings, valves, joints, tees, and bends.

A heat insulating protective member including an inorganic fiber formed body having a hollow cylindrical shape or a split hollow cylindrical shape, wherein the inorganic fiber formed body has an inner circumferential surface (c) facing a hollow and an outer circumferential surface (a) constituting an outer circumference, and the bulk density of the inorganic fiber formed body increases toward the outer circumferential surface (a).

A method for producing a fibrous web includes: (a) a fibrous ply containing polylactide fibers and, as necessary, other fibers are laid on a substrate in a random fiber arrangement, (b) initially a loose, pre-compressed nonwoven is created by applying a first pressure to the fibrous ply, the tear resistance of which nonwoven permits free bridging of a span between 0.1 m and 1 m before the nonwoven tears, (c) the pre-compressed nonwoven is then passed through the calender gap, wherein a pattern consisting of point or linear pressure zones is formed in the gap, with the fibers in the pressure zones being exposed to a second pressure, which is higher than the first pressure, and to a temperature such that the fibers fuse.

An article with at least two extruded thermoplastic polymer foam pieces that fit together to form a length of foam having a generally annular cross section, each piece having a concave surface such that the concave surfaces adjoin to form an internal edge defining a hole within the generally annular cross section; wherein each piece has a density less than 36 kilograms per cubic meter, a product of density times average cell size that is less than 17 millimeters*kilogram per cubic meter, and a thermal conductivity of 35 milliwatts per meter*Kelvin or less.

A heat protective sleeve includes a body being cylindrical extending along a longitudinal direction and comprising a triply periodic minimal surfaces (TPMS) structure, an open cell foam structure, or a lattice structure. A strip extends along the longitudinal direction of the body. The strip is a same material as the TPMS structure, the open cell foam structure, or the lattice structure. The material of the strip is solid and without holes through it. An endcap removably couples to the body. In some examples, the body has fastening threads and the endcap has mating threads. The mating threads of the endcap are configured to engage with the fastening threads of the body to releasably couple the endcap to the body.

A method protects a field joint of a pipeline, where chamfered edges of thermally-insulating parent coatings on conjoined pipe lengths are in mutual opposition about a longitudinally-extending gap. The method includes manufacturing an hourglass-shaped inner layer around the pipe lengths, which layer may be moulded. The inner layer extends longitudinally along the gap between the chamfered edges and at least partially overlies the chamfered edges. A thermally-insulating solid insert is assembled from two or more parts to lie in the gap surrounding the inner layer, and pressure is applied radially inwardly from the insert to the inner layer. An outer layer of molten material is manufactured around the insert to form a watertight barrier and to form one or more melted interfaces with the inner layer. Corresponding field joint arrangements are also disclosed.

A protective fabric jacket for placement on an object to be protected from excessive heat includes a first layer; a second layer; and an intermediate spacer fabric layer that is disposed between the first layer and the second layer. The first and second layers are attached to the intermediate spacer fabric layer to form a layered structure. The intermediate spacer fabric layer comprises a flexible honeycomb or octagonal shaped spacer fabric that has a plurality of cells defined therein. The protective fabric jacket also includes a settable material that disposed within the cells and includes a cementitious mixture and one or more organic polymers and is settable to a hardened material.

A system for compressing and packing pipe insulation includes a compression member that is movable along a first axis to compress pieces of pipe insulation. A stacking bay includes opposing walls that are spaced apart from one another. At least one of the two opposing walls is movable relative to the other of the two opposing walls along a second axis to adjust a lateral distance between the opposing walls to accommodate an increasing size of the pieces of pipe insulation along the second axis. The first axis is generally orthogonal to the second axis. A packing member that applies a force along a third axis to the pieces of pipe insulation after being compressed. The third axis is generally orthogonal to the first and second axes. The first axis is generally orthogonal to the second axis. The compression member is aligned with a space formed between the opposing walls.
