Application of Boiler Tubes

1.The general boiler tube use temperature is below 450 °C, and the domestic tube is mainly made of 10 or 20 carbon steel hot rolled tube or cold drawn tube.

2.High-pressure boiler tubes are often subjected to high temperature and high pressure conditions, and the tubes will oxidize and corrode under the action of high temperature flue gas and water vapor. Steel pipes are required to have high durability, high corrosion resistance and good structural stability.

Use of boiler tubes:

  1. General boiler tubes are mainly used to manufacture water-cooled wall pipes, boiling water pipes, superheated steam pipes, superheated steam pipes for locomotive boilers, large and small smoke pipes and arch brick pipes.
  2. High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air ducts, main steam tubes, etc. for high-pressure and ultra-high pressure boilers. The supply and demand trend of the high-pressure boiler tube industry is generally stable, but the supply and demand situation of each specific sub-sector will be further differentiated. Insiders pointed out that the most critical link is the use and promotion of new energy-saving insulation 20g high-pressure boiler tube equipment.

Rust Removal of the Boiler Tube

There are several methods for removing rust from the boiler tube, the simplest being cleaning using a solvent and emulsion. However, this can remove only dust, oil, etc. but will not rid the pipe completely off organic remnants.

The second method is rust removal using manual or power tools. Tool cleaning can get rid of oxide coatings, welding slag and rust.

The most common method is through chemical and electrolytic methods, also known as acid cleaning.

Spray rust removal is the most ideal method for cleaning of the boiler tube as it can remove dirt, oxide and rust to a greater level. Furthermore, it can increase the roughness of the pipe.
