Abstract: Structural plates and methods of constructing arch-shaped structures using structural plates. Structural plates may include a combination of features including: an outer structural plate having adjacent circumferential apertures respectively spaced nominally greater than adjacent circumferential apertures of an inner structural plate; and the outer structural plate having nominally 5 enlarged or differently shaped circumferential apertures (as compared to circumferential apertures of the inner structural plate) such that the embodiment structural plates may be radiused to a variety of different radii while achieving desirable overlapping alignment of apertures along overlapping circumferential edges for receiving fasteners therein. Joiner plates may be provided for interconnecting structural plates along transverse edges in a non-overlapping arrangement, 10 thereby reducing the quantity of structural plate material that otherwise would be needed for a given circumferential length of the arch-shaped structure.

Abstract: The present invention relates to a tubular section which may be constructed from a sheet having a pair of opposed edges. The opposed edges are releasably connectable such that the section may be stored in a relatively flat configuration. The screw fasteners used to connect the edges together may be restrained from rotation using for example a stringer element appropriately stabilised relative to the fasteners.

Abstract: A thermal guard for pipes to protect personnel from hot or cold pipes in refineries, chemical plants and other places processing hot or cold fluids. The guard is made from metal and contains no insulation so that the pipes are readily visible for observing leaks and can be readily repaired. The guard is fabricated from a few easily fabricated and assembled parts which can be attached to pipes of various sizes.

Abstract: A piping assembly has spacers which are positioned on a pipe and spaced apart one from another along a length of the pipe. Each of the spacers extends from a perimeter of the pipe to a spacer perimeter surface which is interrupted by at least one gap defined by two spacer edges which extend towards the pipe perimeter from the spacer perimeter surface in a direction transverse to the spacer perimeter surface. A sleeve having apertures therethrough which form a mesh is positioned on and circumscribes the perimeter surfaces of at least two spacers and has edge portions bent at positions to extend to the spacer edges so that the sleeve is held in position on the spacers.

Abstract: A hollow housing case of an electriclly conducting plate which has one insulating surface includes a connecting part to connect together electrically both ends of the plate.
