use of a tube of synthetic material such as pipe of fuel for motor vehicles protected in the event of an accident

摘要

the use of a tube of synthetic material extruded to smooth walls formed from a synthetic material for thermoplastic pipes, usual for motor vehicleswith an outside diameter less than 15 mm and with a sufficient thickness of the wall as the main fuel for motor vehicles protected in the event of an accident that is connected.through connections with a predetermined removal facilities associated with the motor vehicle.the main fuel for motor vehicles has segments of security for the case of an accident with longitudinal section of corrugated pipe shaped in the form of synthetic materials duringthe extrusion or after the extrusion, the total length in the state road is more than 50% of the length of the pipeline of "virgin" fuel for motor vehicles already suppliesthe segments of the security for the case of an accident, and that, in the event of an accident, maintain the forces due to the extension less than corresponds to the predetermined removal force (k2? , k1).
