摘要

PIPELINE FORMED OF PIPE SECTIONS CONNECTED BY ELASTIC COUPLING ELEMENTS A pipeline formed of separate pipe sections provided with a corrosion-resistant insulation and successively interconnected therebetween. Outer coupling elements are provided for joining the pipe sections. These coupling elementa are substantially elastic and are brought into contact by their entire surface with joint portions of the pipe section. Recesses are provided at the ends of the pipe sections and serve to accommodate the coupling elements therein.
