Abstract
The utility model relates to a compound steel pipe with an outer reinforced resins coating and an inner epoxy resins coating for an underground coal mine. The pipes used for the underground coal mine are mostly pure plastic pipes for mining or ordinary steel pipes. When in application, the pure plastic pipes for mining have the problems of low in pressure bearing, difficult in connection, and poor in flame retardant capacity, and the ordinary steel pipes can not completely satisfy anti-static requirement, corrosion prevention requirement, and other specific performance requirements of the pipes used for the underground coal mine. After the inner surface and the outer surface of the ordinary pipes are processed, the reinforced resins are coated and winded on the outer surface of the steel pipe, and the epoxy resins are coated and on the inner surface of the steel pipes to form the compound steel pipe with the outer reinforced resins coating and the inner epoxy resins coating for the underground coal mine. The compound steel pipe with the outer reinforced resins coating and the inner epoxy resins coating for the underground coal mine has the advantages of being high in pressure bearing, impact resistant, flame retardant, static resistant, corrosion resistant, long in service life, and convenient to install. The damaged outer surface coating is easy to repair and the compound steel pipe with the outer reinforced resins coating and the inner epoxy resins coating for the underground coal mine can be applied to water supply and drainage of the underground coal mine, compressing air, grouting, fire protecting sprinkling, and gas drainage.
Description
Technical field
The utility model relates to underground mine use tubing, particularly relates to the underground mine use outer fiber and strengthens epoxy coating composite steel tube in the resin.
Background technique
Underground mine use tubing pure plastics mining pipes or the common steel tubes of adopting more, the pure plastics mining pipes pressure-bearing in the practical application is low, the connection difficulty, and fire retardancy is poor; Common steel tube can not satisfy under the mine the specific usability requirement with tubing fully at the aspect such as antistatic, corrosion-resistant.
Summary of the invention
The utility model is through after the process treating the inside and outside surface of common steel tube, twine fiber-reinforced resin in the outer surface of steel tube coating, internal surface coating epoxy resin and the underground mine use outer fiber made strengthens epoxy coating composite steel tube in the resin, integrate the mechanical property of steel and the corrosion resistance of epoxy coating, satisfy the specific usability requirement of underground mine use tubing.
The technological scheme that its technical problem that solves the utility model adopts is: fiber-reinforced resin through after the process treating, is twined in the outer surface of steel tube coating in the inside and outside surface of common steel tube, internal surface coating epoxy resin.
The beneficial effects of the utility model are: provide a kind of New Coal Mine down-hole special-purpose tubing---the underground mine use outer fiber strengthens epoxy coating composite steel tube in the resin, has the pressure-bearing height, and is shock-resistant, fire-retardant, antistatic, corrosion-resistant, long service life, the outer wall coating is damaged easily and is repaired, the characteristics such as easy for installation, be applicable to plumbing under the coal mine, press wind, slip casting, the fire-fighting watering, gas is taken out the engineerings such as anti-.
