Problems solved by technology

However, due to the corrosiveness of the conveying liquid medium and the abrasiveness of materials containing dust, the service life of steel pipes is greatly reduced, and the maintenance cost and repair period are increased. Ordinary steel pipes cannot meet the requirements of long-term use of pipes.
The existing wear-resistant and anti-corrosion technology for steel pipes in this field mainly includes wet vertical fired enamel pipes. The advantages of this pipe are long service life, corrosion resistance and wear resistance of steel pipes. However, the production line is expensive and the process Complex, thin porcelain layer, high production cost, and there are difficulties that the super long pipe cannot be fired as a whole and the inside of the super long pipe cannot be glazed

Abstract

The present invention relates to production equipment and method for steel pipe with composite inorganic material coating. The production equipment includes mainly one sand blasting section comprising deduster, sand blaster, sand blasting pipeline, belt conveyer, bucket type lifter, sand bin, etc.; and one enamel baking section comprising drawing bogie, medium frequency heating furnace, medium frequency machine, rack, glaze feeder, etc. It features the sand blasting process while turning the steel pipe, and the simultaneous heating, glaze spraying and enamel baking process. The present invention has simple technological process and low production cost, and the produced ultra long steel pipe has high wear resistance, high corrosion resistance and long service life.

Description

Technical field: [0001] The invention relates to a production equipment and a production method for conveying pipelines for liquids such as petroleum, chemical industry, thermal power stations, metallurgy, and materials containing dust gas. Background technique: [0002] At present, steel pipes are mostly used for the transportation of liquids such as petroleum, chemical industry, thermal power plants, metallurgy and other materials, as well as materials containing dust gas. The pipes are due to their high strength, good toughness, convenient construction, good wear resistance, and high safety factor. It is an irreplaceable material for pipelines in this field. However, due to the corrosiveness of the conveying liquid medium and the abrasiveness of materials containing dust, the service life of the steel pipeline is greatly reduced, and the maintenance cost and repair period are increased. Ordinary steel pipelines cannot meet the long-term use requirements of the pipeline. ...
