Jacket Tube

HFFR PE Sheathed Tube

Cross sectional layer as 1 core tube with out sheath by TPU, PE material. Sheath is recommended for product oil (Naphta, Gasoline, Fuel oil, etc.) carriers where PVC Sheath is not applicable, Shipyards conventionally installed bare tube without sheath in product oil tanks so the tube was bare exposed to corrosion. In order to prevent the possible tube corrosion in the tanks TPU, PE sheathed Jacket Tube (non-adhesive) is highly recommended for product oil carriers. TPU, PE material properties are not available with adhesive.
