How many mm need to be cut off from the steel pipe or steel plate after flame cutting?
Thread Content
Experts: When using flame to cut steel pipes or steel plates, what distance in millimeters constitutes the heat-affected zone, and how many millimeters need to be removed? Which standard specifies this?
Different materials have different requirements. For example, low-carbon steel only needs to have its oxide layer removed, but for high-alloy heat-resistant steel pipes, flame cutting is not recommended or allowed; gas cutting is required to remove the heat-affected zone
Hello, expert. For low-carbon steel, it is only necessary to grind off the oxide layer – which standard specifies this requirement? Could you let me know?
Check GB50235 and 50236; it’s there
Yu always answers very clearly: lol
