Fluid line connection arrangement, especially for connecting pressure and liquid-tight sealed flexible hoses to rigid metal connecting lines, has connecting collar lasered onto end section of first line of weldable thermoplastic material

摘要

The arrangement has a second line (2) in the form of a rigid mechanical connection line of a throughflow heater to which a metal connecting collar (5,7) is soldered. The connecting collar of a first line (1) has an annular outer hose section of laser beam transmissive, especially thermoplastic material and a coextruded annular inner hose section of laser beam absorbing, weldable, especially thermoplastic material. The connecting collar is lasered onto the end section of the first line of weldable, especially thermoplastic material.
