The open joint-stock research and production company FiBr-Porolen has organized a pilot production of composite materials. The materials are superfine powders for corrosion-resistant coating of pipes, equipment and pipe coupling elements.
In association with Gubkin Russian State University of Oil and Gas (Moscow), the company has developed an effective method of fine polyolefin grinding by simultaneous application of high pressure and deformation through a shift in premelting interval. This makes it possible to significantly reduce energy consumption in polymer powder production.
Scope of application for the superfine polymer powder:
- corrosion-resistant coating of curved elements (bends, T-bends, crossovers, gate valves etc);
- use as an adhesion coating layer in three-layer coating of big diameter pipes;
- corrosion-resistant and wear-resistant protection of metallic elements of purpose-build equipment.
Main coating methods for the superfine polymer powder:
- coating by applying the polymer powder within an electric field;
- extrusion coating by applying a polyethylene melt with an interlayer;
- extrusion coating by applying a polyethylene melt without an interlayer.
In summer 2006 a pilot testing site in Dolgoprudny city of Moscow Region was created for production and application of the polymer powders. The first samples of elements and materials received high appraisal from manufacturing plants.
The project has gathered support at the annual CITOGIC-2006 congress held by OAO Gazprom as perspective and relevant for Russian oil-and-gas industry.
The project by OJSC R&P FiBr-Porolen ranked first in a competition for investment attraction in the Technological Business Incubator, which was carried out by the Administration of Tomsk Region.
OJSC R&P FiBr-Porolen is organizing a pilot production of powdery composite materials from composition granules of polyethylene, sevilen, block copolymer, stat-polypropylene and/or compositions of these.
Superfine composite powders can be used for:
- corrosion-resistant,
- friction-resistant,
- anti-static,
- decorative,
- adhesion-resistant coatings.
Moreover, the powders can be used to make powdery modifiers in production of:
- protective coating for pipes and equipment, including those used in refineries;
- protective coating for pipe coupling elements, valves;
- asphalt concrete with enhanced freezing resistance and reduced water absorption capability;
- polymer-wood boards (to replace binders – phenol-formaldehyde resins);
- polymer-bituminous mastics;
- engine oils (as a thickener);
- additives to oils and lubricants (as sliding agents).
Applying the powdery composite polymer-based protective coating to inner and outer surfaces of pipes and coupling elements within an electric field extends the service life of pipes and refinery equipment to 15—20 years.
