A ventilation duct for a fire rated ventilation duct wall penetration has one or more metal sheets forming said duct, wherein said metal sheet duct is covered on the outside by a heat insulating material, and said duct includes elongated stiffening members located on the outside of the duct and attached to said metal sheets. The stiffening members each comprises a metal profile and at least one non-combustible bar of inorganic material. The metal profile is fixed to the metal sheet of the duct and retains the non-combustible bar by at least partly encircling the bar.

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 flexible fluid containment covering is provided which is configured for temporary engagement over a leak in a pipe carrying fluid. A flexible body of the covering is positionable upon a leaking pipe to channel leaking fluid downward through an exit from a gap formed between a first half portion and second half portion of the body. Channels may be positioned on the contact side of the body to direct fluid downward. When placed upon a leaking pipe, the covering prevents fluid from spraying upward and outward and allows for container collection of the fluid.

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 fire insulation precursor material formed of cement, in an amount of between 10-30% w/w; and an aluminium or magnesium hydroxide, huntite or hydromagnesite in an amount of between 60-90% w/w/. A fire insulation material is provided including the previously mentioned precursor material. Further described are methods of forming a fire insulation material and applications for such material in sheaths, duct coatings, cable trays and other elongate components.

Mineral wool insulation products are provided. The mineral wool insulation includes a plurality of mineral wool fibers and a wax emulsion applied to the mineral wool fibers. The wax emulsion imparts excellent water resistance and thermal performance properties to the mineral wool insulation.

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.

Methods and systems for duct protection of a vehicle are provided. The methods and systems provided include an apparatus for containing a flow of fluid discharged from a fracture in a duct. The apparatus includes a ballistic containment layer and an insulation sheath coupled to the ballistic containment layer. The insulation sheath includes a first air containment layer, an insulation layer, and a second air containment layer.

A thermally-insulating composite material with co-shrinkage in the form of an insulating material formed by the inclusion of microballoons in a matrix material such that the microballoons and the matrix material exhibit co-shrinkage upon processing. The thermally-insulating composite material can be formed by a variety of microballoon-matrix material combinations such as polymer microballoons in a preceramic matrix material. The matrix materials generally contain fine rigid fillers.
