DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a method for providing fire and corrosion protected objects, preferably pipe and/or pipe systems.
Further, the present invention relates to a method for providing substantially pipe- or hose-shaped fire protected objects, preferably a conduit for carrying fuel from a source to a use apparatus, for example a propulsion motor in a vessel, or especially a motor vehicle.
The invention also relates to fire and corrosion protected objects, as well as substantially pipe- or hose-shaped protected objects.
PRIOR ART
In connection with industrial process plants, for example chemical plants or oil refineries, etc., it is usual that steel pipes are used for the transmission of the raw material which is to be treated, and the materials included in the treatment. Steel pipes are used due to their resistance against heat and fire. The liquids and/or gasses passing through the pipes are however often corrosion promoting, and will therefore subject the steel pipes to heavy corrosion. In connection with oil refineries for refining offshore oil which is often mixed with salt water and other impurities, the pipes are subjected to severe corrosion. This implies that the frequency of maintenance is high, which in turn requires that the operations be stopped for control and maintenance. Consequently, the corrosion problem involves losses in productivity, and also represents a danger of leakage and plant failure.
Further, in connection with propulsion motors in vessels, and motor vehicles, it is of greatest importance that the conduit carrying fuel from the gasoline tank to the motor, be well protected against fire, such that the gasoline supply system remains a protected system as long as possible after the occurence of a fire on the vessel or in the vehicle.
A requirement to be met by the gasoline pipe or the gasoline hose which is to be mounted between the gasoline tank and the gasoline intake of the motor of a car, is that the conduit itself should be bendable or flexible, so that it can easily be mounted along the framework of the vehicle, said conduit also being so effectivly insulated agains fire that the driver and passengers will have time to leave the car in case of fire.
Within the car industry there are certain specifications concerning the length of time a gasoline pipe should resist a fire. The period of time varies depending on the classification of the vehicle. For example, it is a question of 90 seconds in connection with certain types of vehicles and certain types of fire apparatus, whereas for other vehicles the period of time can be approximately five minutes.
DISCUSSION OF THE INVENTION
An object of the present invention is to provide fire and corrosion protected articles, preferably pipes and/or pipe systems which meet the specifications for steel pipes as regards corrosion resistance and heat resistance, said articles according to the present invention being produced from inexpensive material, permitting installation in the form of pre-fabricated elements, and permitting simplified control and maintenance of the installed articles.
A further object of the present invention is to provide pipe- or hose-shaped fire protected articles, which are useful to supply fuel from a source to a consumption apparatus, for example a propulsion motor on a vessel, which resists high temperatures and the effect of flames in case of fire in the motor or the vessel. The fire protected article should also be flexible, or at least bendable for mounting without bending the conduit with special tools. Further, the article is manufactured from relatively inexpensive materials, for example in running lengths which are delivered in finished fire protected condition to the place of installation.
These objects are achieved in a method which according to the invention comprises an inner pipe of plastic, for example a polymer, a light, thermally insulating material which normally does not stand exposure to fire covers the inner pipe, and around the light, thermally insulating
