A method of crushing and bending an end section or an intermediate section of a tube comprises placing in a cradle of a die of a press a part of the tube including the section, and moving a punch of the press towards the die such that the section and the remainder of the tube part are bent one relatively to the other and one wall portion of the section is crushed inwardly towards a diametrically opposite wall portion of the section. The tube having a section so crushed and bent can be connected to another tube, for example, by disposing the section face-to-face with a complementarily shaped portion of the other tube such that the remainder of the part extends away from the latter portion, and then, for example, welding or bolting the section to the other tube. |
