Title: Electrically weldable joining member for application to pipeline parts
Inventor: MEIER MAX
IPC: F16L47/32

Abstract: The connecting element is an electrically weldable sleeve (1) which has a sleeve body (2) and a heating wire winding (3) with heating elements (4, 5) and terminals (8, 9) for the supply of electrical power. Conduit ends (6, 7) are inserted in the sleeve (1). To weld the sleeve (1) to the conduit ends (6, 7) a fusing zone is generated electrically in the heating elements (4, 5). In order to position the heating wire turns (10) of the heating elements (4, 5) precisely and, during welding, to avoid adversely affecting the welding power by turns of wire that become free in the fusing zone making contact with each other, the resistance heating wire (11) is surrounded with a first envelope (12) of a material which cannot combine with the material of the sleeve body (2), and a second envelope (15), which consists of a material which is identical to or compatible with the material of the sleeve body (2). The cross-section of the second envelope (15) has a straight circumferential part (16) which on the one hand forms the concave inner wall of the sleeve body (2) when producing the sleeve (1), and on the other hand positions the relative location of the resistance wires with respect to the predetermined welding energy output per unit area. <IMAGE>

Abstract: PCT No. PCT/AU95/00378 Sec. 371 Date Dec. 26, 1996 Sec. 102(e) Date Dec. 26, 1996 PCT Filed Jun. 27, 1995 PCT Pub. No. WO96/00305 PCT Pub. Date Jan. 4, 1996Yield strength of a cold rolled steel section is increased and controlled by performing a predetermined amount of strain by way of cold working in an in-line roll forming process followed by a controlled amount of strain aging wherein the temperature of the steel section is elevated to a point below 500 DEG  C. and held at an elevated temperature for a time up to 30 seconds. The heating typically takes place by induction heaters (16) and the time aging may be provided in an in-line galvanizing bath (17) before cooling the steel in a quench bath (18). The effect is further enhanced by further cold working and the consequent additional strain in forming rolls (19). For a given steel composition the degree of yield enhancement can be controlled by the temperature and tie parameters and also by the degree of initial roll forming in shaping rolls (10).
