    Abstract: The invention relates to an unbonded flexible pipe with a longitudinal axis and which comprises from inside outwards a carcass formed by metal windings with gaps between neighbouring windings, at least one covering tape and an inner sealing sheath of a polymer extruded onto the covering tape. The covering tape is helically wound with a winding direction defining a tape length direction and a tape width direction perpendicular to the tape length direction. The covering tape comprises lengthwise continuous filament yarns arranged in the tape length direction of the covering tape. The covering tape has a thickness direction perpendicular to the tape length direction. The warp yarns have a thickness determined in the thickness direction of the covering tape of about 100 μm or less, such as of about 50 μm or less, such as from about 5 to about 25 μm.

    Abstract: The invention relates to a thermal insulating element. The element comprises a base material comprising one first series of hole configurations, said first series comprising a plurality of elongated interior holes. Each comprises a central hole axis (A) along its elongation, each central hole axis extending substantially mutually in parallel to each other along a first longitudinal direction. Each hole in a plane perpendicular to the first general longitudinal direction comprises a cross sectional hole shape. The elastic modulus E of said base material along said first longitudinal direction is equal to or larger than 1.5 GPa. The thermal insulating element is suitable for varying and high pressure environments. Further, the invention relates to armored unbonded flexible pipes comprising such a thermal insulating element. Further, the invention relates to a method of manufacturing such an element and a method of manufacturing such an armored unbonded flexible pipe.
