lengths similarly the fillets can have the same or differing widths furthermore the arc length of a segment and the width of a fillet can be constant along the length of the pipe or can vary in addition it is possible either to employ barrier layer polymers which are compatible with the respective sheathing polymer or those which are incompatible this is a significant advantage of the present invention since complex modification of materials is not necessarily required and therefore virtually any material combination suited to the application can be used the pipe of the invention can also comprise two different sheathing layers compatible with one another or bonded to one another via an adhesion promoter in each of which at least one segmented barrier layer can be embedded the barrier layer polymers embedded in the various sheathing layers can be of the same material or can differ thus for example the following arrangements of layers are conceivable antistatic properties can also be imparted to the present pipe which characteristic is particularly advisable when flammable substances are to be transported suitable methods of imparting antistatic properties are known in the art for example the sheathing layer b can contain an electrically conductive additive on practical grounds and in order to save materials however it is recommended that a thin electrically conductive internal layer is provided as disclosed in de 40 25 301 the material of the internal layer should be chosen so as to provide a physical bond to the next layer a further possibility is.
