METHOD FOR PRODUCING PIPE-IN-PIPE SYSTEMS

摘要

The invention relates to a method for producing pipe-in-pipe systems (1) consisting of an outer pipe (2) and an inner pipe (3), where at least one inner pipe (3) and one outer pipe (2) are mechanically connected to each other by applying a contact pressure. A stable connection of pipe-in-pipe systems is achieved by applying the contact pressure from outside to the outer side of the outer pipe (2).
