A method of forming a flat bar is provided. A tube is provided having an inside surface and an outside surface. The outside surface of the tube can be clad with a nickel or stainless alloy material. A helix shaped strip can be cut from the tube. The helix shaped strip can be uncoiled to form an uncoiled strip, and the uncoiled strip can be straightened and flattened to meet mill standards.

The present invention provides a corrosion-resistant structure for a high-temperature water system comprising: a structural material 1; and a corrosion-resistant film 3 formed from a substance containing at least one of La and Y deposited on a surface in a side that comes in contact with a cooling water 4, of the structural material 1 which constitutes the high-temperature water system that passes a cooling water 4 of high temperature therein. Due to above construction, there can be provided the corrosion-resistant structure and a corrosion-preventing method capable of operating a plant without conducting a water chemistry control of cooling water by injecting chemicals.

An array of tile assemblies is fixedly connected to a common waterwall panel to form a refractory liner for an incinerator. Each tile assembly includes a unitary, clip-type, metallic anchor, which is directly welded to the waterwall panel, and a solid refractory tile slidably connected to the anchor through a dovetail locking mechanism. The rear surface of the refractory tile includes a longitudinal rib from which projects a dovetail pin configured to receive the anchor. The longitudinal rib increases the overall thickness of the refractory tile through the region of interconnection with the anchor. In this manner, the anchor is suitably protected by the refractory tile from intense heat which may otherwise cause mechanical failure in the locking mechanism. Additionally, the solid construction of refractory tile both limits the presence of air gaps within the tile assembly and reduces the likelihood of tile fragmentation or cracking.

The present invention is in the field of a high pressure heating installation and in particular a waste incineration installation comprising an advanced panel design and cladding thereof. Said cladding relates to a cladding to a in particular at least partly curved surface of a membrane panel, which panel is used in a high temperature and high pressure incinerator, such as a waste incinerator.

A coaxial heat transfer tube (100), comprising a first inner heat transfer tube (110) having straight parts (111, 113, 115, 117) and curved parts (112, 114, 116), a first outer heat transfer tube (120) having straight parts (121, 123, 125, 127) and curved parts (122, 124, 126). The first outer heat transfer tube (120) radially surrounds the first inner heat transfer tube (110) at least within the first primary straight part (121) and the first primary curved part (122). Thermally insulating material (530) has been provided in between a curved part (122) of the first outer heat transfer tube (120) and a curved part (112) of the first inner heat transfer tube (110). Neither a straight part (121) nor a curved part (122) of the first outer heat transfer tube (120) comprises a longitudinal seam. A method for making a coaxial heat transfer tube (100).

A boiler tube reinforcement device reinforces a boiler tube including a first boiler tube, a second boiler tube, and a weld portion joining edges of the first boiler tube and the second boiler tube together. The boiler tube reinforcement device includes: a sheet-shaped first steel plate wrapped in a region including the weld portion of the boiler tube and reinforces the boiler tube, the first steel plate including a plurality of bending portions, the bending portions being formed along a longitudinal direction of the boiler tube at regular intervals along a circumferential direction of the boiler tube, wherein the first steel plate is wrapped in the region of the boiler tube.

The method for fabrication of corrosion-resistant tubing using minimal quantities of specialized material results in corrosion-resistant tubes with a reduced capital cost. In contrast, the disclosed method uses a straight weld made along the length of the tube, rather than a spiral weld that follows its circumference. The straight weld passes up and down the tube, but only on one side, or approximately 50%, of the tube. Following application of the corrosion-resistant material by straight welding, two or more tubes are joined together into an array.
