A pipe, the inner surface of which is lined with a thermoplastic layer, is produced by a process comprising the following steps: Relative movements between the metal pipe and inliner are thereby prevented; the inliner also has high safety against collapse. The pipe is used to produce a routed pipeline.

Method for producing a pipe lined with an inner liner

A process for producing a thermoplastic composite pipe, where the process includes:

Thermoplastic composite pipe with multilayer intermediate lamina

The invention relates to plastics composite moldings obtainable via welding in an alternating electromagnetic field, in which the weld is obtained with the aid of a plastics material which comprises nano-scale, magnetic oxidic particles, which are composed of aggregated primary particles, and where the primary particles are composed of magnetic metal oxide domains whose diameter is from 2 to 100 nm in a non-magnetic metal oxide matrix or non-magnetic metalloid oxide matrix.

Plastic composite moulded bodies obtainable by welding in an electromagnetic alternating field

Multilayer composites are obtained from a molding composition which contains the following components:

Use of a polyamide molding composition with high melt stiffness for coextrusion with a high-melting-point polymer

A process for the bonding of a plastics pipe to another plastics part by ultrasound welding using sound waves which act longitudinally with respect to the pipe axis, while the arrangement of the areas to be welded is substantially parallel to the pipe axis. The welding procedure is combined with the forced insertion of the other plastics part into the plastics pipe in such a way that there is at least some overlap between the exposure to sound and the forced insertion.
