摘要： A fluid line having a wave form portion is furnished. The wave form portion extends at least at a minimum distance along a longitudinal axis of the fluid line. The wave form portion has a wave peak element (18), which itself has, along a peripheral direction extending around the longitudinal axis of the fluid line, a varying distance from the longitudinal axis, the distance including a distance curve in the peripheral direction, the distance curve providing a non-circular contour. A fluid line is thus provided having a wave form portion, which fluid line reduces the pressure drop at the wave form portion.

摘要： Screw connection, in particular, a tension clamp, and method of forming the screw connection. The screw connection includes a screw having a screw head and an external thread with a thread turn profile and a thread axis, and a mating thread element having an internal thread, matched to the external thread, with at least one thread groove bordered by thread flanks to screwably receive the screw. A geometrically defined deformation of the external thread is arranged at a predetermined distance from the screw head to collide with at least one thread flank during the screwing of the screw into the mating thread element.
