Production characteristics of high pressure boiler tube
The production characteristics of high-pressure boiler pipe
1. Tube. High surface quality requirements, the need for stripping, an amount of 5 mm strips, some plants take black grinding.
2. Tube cutting. Hard steel, the use of flame cutting or sawing.
3. Heating. Poor thermal conductivity, and therefore to control the furnace end temperature. The heating temperature is generally 1120 ~ 1180 ℃.
4. Rolling. Such steel is generally better performance perforation, deformation parameters can be selected carbon steel.
5. Rolling after heat treatment. Such pipe after rolling to normalizing and tempering. Air cooling after hot rolling and then take some factories in 730 ~ 740 ℃ tempering.
Higher steel tube geometry requirements in order to ensure a good counterpart welding, pipe length should be as long as possible, helps to reduce the number of welds.
