Abstract
An assembly including a series of tubes attached to a base tube sheet wherein the tube sheet is provided with relatively light corrosion resistant material at both sides, the sheet then being drilled through, corrosion resistant sleeves placed in the holes drilled, and corrosion resistant tubes located and fixed in the sleeves by rolling and welding.
Claims6
A joint for a tube to extend through a steel sheet, there being a hole through the steel sheet, corrosion resistant material at both sides of the steel sheet, a corrosion resistant sleeve located in hole welded to the corrosion resistant material at both sides of the steel sheet, thus isolating the hole from the steel sheet by corrosion resistant material, and a corrosion resistant tube in the corrosion resistant sleeve, said tube being secured to the sleeve at one side only of the sheet,
- the corrosion resistant sleeve terminating at the exterior surfaces of the corrosion resistant material covering the sides of the steel sheet, and
- adjacent corners of the corrosion resistant sleeve and sheets on both sides of the tube sheet being bevelled forming V-grooves for welding.
