A fireproof cladding material for covering or coating a plastic pipeline, includes a cross-sectional structure formed by needle punch or thermal bond to form a two-layer or three-layer laminated structure with an integrated structure. The laminated structure of the cross-sectional structure is composed of a fireproof fiber woven blanket having a thickness of 0.2-250 mm, and an upper side or a lower side of the fireproof fiber woven blanket, or both sides of the upper side and the lower side thereof, is composed of a fireproof reinforcement layer with a thickness of 0.015-0.5 mm. The fireproof cladding material has the characteristics of softness, bendability, light weight and high strength, and is suitable for covering or coating plastic pipelines.

A fire protection element includes a mat of intumescent material, a reinforcing liner and ventilation holes. Furthermore, a fire protection wrap is used as a fire protection element of this type.

Process for fire resistant protection of the technical elements of a building by means of one or more prefabricated isolation blocks, enabling pre-isolation of a vacant space in the structure of a building. The block comprises an easily modelled fire resistant material and is disposed before pouring the concrete of the structure of the building. The prefabricated block is then opened up in such a manner as to install the technical elements having to be protected from fire.

A conduit fitting is provided herein. The conduit fitting may be configured to couple to an electrical mechanical tubing (EMT) often used in a fire suppression system. The conduit fitting may include a first cylindrical section and a second conical section. The first cylindrical section and the second conical section can both include a slit extending partially through the conduit fitting.

The present invention concerns a transit for cables, a cable bundle (9) or a bus bar (12). The transit comprises a sleeve (1) having a through opening (2) for receiving the cables or the bus bar (12). The sleeve (1) is to be received in a through opening (5) of a partition (4). A glass fiber tissue hose (7) is placed going through the opening of the sleeve (1). The ends of the tissue hose (7) is wrapped back and placed on the outside of the sleeve (1). One or more intumescent strips (6) are placed between the inside of the sleeve (1) and the tissue hose (7). A fire retarding agent (10) is placed around and between the cables or around the bus bar (12).

An apparatus for limiting event energy in an underground structure having free space includes: an inner layer configured to envelope and seal an interior volume; an outer layer configured to envelope the inner layer; and, wherein the interior volume includes a volume-occupying material, having a solid material, a semi-solid material, a gaseous material, or any combination of the solid, the semi-solid, and the gaseous material.

A line feedthrough for guiding at least one line through a component, contains a cladding tube, at least one element which is mounted within the cladding tube and can rotate relative to the cladding tube, and a sealing element which is in the form of a flexible hose body and arranged within the cladding tube and the element. The hose body is connected, in an axial end region, to the element and can be displaced by rotational movement between a closed position and an open position. A guide element is provided which can be displaced in the longitudinal direction relative to the cladding tube, and which cooperates with a guide track of the element. The guide track of the element is in a spiral shape, such that a displacement of the guide element in the longitudinal direction leads to a rotation of the element relative to the cladding tube.

A cable system is provided which is configured with both electric wires and a fluid conduit running through the axial passage of a surrounding flexible sheath of the cable. The system allows for communication of electricity over the wires for electrical circuits and concurrent communication of a fire ignition suppressant fluid or gas through the fluid conduit, to all points in an electric circuit using the cable. One or both of a dye or scent can be included in the ignition suppressant fluid.

Shatter protection for a high voltage apparatus with a ceramic insulator includes at least one electrically insulating tube including a plurality of holes going through an envelope surface. The electrically insulating tube has a diameter such that there is a minimum distance between the tube and the ceramic insulator when arranged concentrically. A method for producing a shatter protection includes winding a first helix shape of the electrically insulating fiber composite material at a first pitch such that there is a first gap between the winding turns, and winding a second helix shape of the electrically insulating fiber composite material onto the first helix shape in the opposite direction and at a second pitch, such that there is a second gap between the winding turns. Thereby forming a first electrically insulating tube with holes formed by the first and second gap between the winding turns.

A fire protection device is useful for sealing through-openings in wall or ceiling elements made of wood or a similar material, in particular for sealing line or pipe feedthroughs. The fire protection device has a main body and at least one expansion body which is attached to an end face of the main body and contains an intumescent material. Also useful is a fire protection assembly.
