Abstract

The present invention refers to a novel anticorrosion protector for metallic structures and pipes, which is characterised in that it comprises: a first synthetic mineral grease layer including inorganic microfibres. The mineral layer has a thickness of from about 2 mm to about 5 mm, and a length of 7 meters depending on the damaged caused to the metallic structure; the invention also includes a non-woven synthetic cotton strap with petroleum derivatives an antioxidant substances, the strap providing firmness and sealing the damages originated in the metallic structure; a food-grade, odourless, transparent, high-density, hydrophobic propylene film having 2 microns of thickness; a flexible geo-membrane layer comprising black coal at 2.5% and polypropylene at 97.5% for protecting from water, dust, solid impacts, vibrations that is useful for attaching and cover the aforementioned elements, said membrane being applied in lengths no higher than 6 m; the invention also including safety fast eners with buckles. The protector is applied in-situ, the preventive maintenance allowing the useful life of the structure to be extended.

Description

"ANTICORROSIVE PROTECTOR FOR PIPES AND METALLIC STRUCTURES" TECHNICAL FIELD The present invention has its technical field mainly in the areas of Chemistry and Mechanics because they provide a novel Anticorrosive Protector for metallic structures and pipes.

BACKGROUND Currently, the phenomenon of erosion due to the oxidizing action of the different substances, air, water, friction, which alter the physicochemical composition of the metallic structures and pipes for which the following products and anticorrosive protection mechanisms are currently present. Paints and epoxy resins which are applied directly and in situ which are of a density of 1 to 3 mm thick its utility is limited as it does not solve or prevent the progress of the oxidants already installed on the metal surface covering only for new erosions highly toxic and flammable. Laminated sheet metal roof which only serves to contain minor leaks without correcting or preventing the effects of oxidation. Thermal cover which is applied only in the manufacture of the pipes which limits its usefulness, preparation and conservation of the metallic structure. Thermoformed products are applied in the factory and have limited life to the handling and biological changes of the areas where they are installed, they do not provide maintenance or correction to the damage to the metallic structure. Laminated plastic is applied directly in the factory does not allow maintenance to the metal structure. Fiber layers only serve as thermal protector, not as anticorrosive DETAILED DESCRIPTION OF THE INVENTION The characteristic details of this innovative anticorrosive protector for pipes and metal structures are clearly shown in the following description: The anticorrosive protector is mainly composed: a) A first layer of synthetic mineral grease added with inorganic, anaerobic, green grease micro fibers, this layer functions as a sealer of the oxidants, forming a staging of the oxides or magnetites. The mineral layer has a thickness of 2 to 5 mm. and a length of 7 m. in its application depending on the damage that presents or has suffered the metallic structure; b) It is a synthetic non-woven cotton tape added with petroleum derivatives and antioxidant substances which serves to firm and seal the damage suffered by the metal structure, is applied in situ in a circular manner with overlaps of 55% minimum to cover one length no greater than 6 meters eliminating the entry of air or aerobic bacteria to the surface of the structure; c) A food-grade, hygroscopic, hygroscopic, high-density polypropylene film of 2 microns density, used to compress and allow dilation and resilience of the above products and containing each of them in its place, is applied in a circular manner enveloping and double twist in 60% overlaps with a length no greater than 7 meters; d) A geo membrane layer composed of 2.5% black carbon and 97.5% polypropylene in the flexible mine which serves to protect from water, dust, solid impacts, ground vibrations and clamping and cover for the above elements is applied in lengths not more than 6 meters and e) Safety straps made of 5052 grade 14 aluminum with buckles of the same material or stainless steel applied with tension of 60 lbs which serve to fasten and seal the aforementioned layers. This belt is placed 25 to 50 cm away from each other depending on the geographical location when it is under water and shallow currents every 30 cm. when it is live streams to surge tides every 25 cm. same as in spring containment piles, when it is outdoors at 50 cm. and underground at the same distance.

Application of the anticorrosive protector for pipes and metal structures For the correct application of the anticorrosive protector it is necessary to follow the following steps: I. Apply a first layer of synthetic grease with a maximum length of 7 m to the fissured structure. II. Apply on the fat layer a non-woven synthetic bandage in 55% circular overlaps with a length of 7 m. III. Apply a high density plastic film in 60% overlaps with double rotation in a length of 7 m. IV. Apply a 6 m membrane geo membrane. of subject length. V. Apply aluminum straps with clips of the same metal or stainless steel at a distance of 25 to 50 cm. between them with a pressure of 60 lbs.

It should be mentioned that in steps I and III the application of the layers is 1 m long. greater since with this we avoid the pollution by dust, water and air to the layer of bandage of synthetic material.

Based on all the above described we can say that the present invention provides the following benefits: • The application of the protector is insitu allowing the preventive maintenance to lengthen the useful life of the structure. • Once the protector is applied, erosion and physical chemical damage to the structure is eliminated. • In case of emergency, it serves as a contingent material, sealing cracks or fractures in case of emergency. • The protector is easy to prepare and apply.

Once applied allows the flow of contents without any problem for up to 10 hrs. time in which repairs can be made. This protector does not cause damage to the environment as it is not toxic or contaminant of continuous release as solvents or corrosive as laminates. Applied of this protector contributes to the elimination of spills since the properties of the different products have an elongation and flexion of up to 13%.
