Heat treatment issues for tower renovation!
Thread Content
Our company will carry out modifications to the catalytic unit in June; the internal fixings in several of the towers need to be changed. The design agency says that heat treatment is required whenever welding is done on the tower structure. Could you please inform me about the costs associated with heat treatment as well as the difficulties involved in its implementation? I would also like to know if other companies in the catalytic unit industry also carry out heat treatment during similar modifications of equipment. Thank you!
Yes, heat treatment is required. The reason is to prevent stress concentration at the weld area. In practice, this involves wrapping the area that needs heat treatment with a heating wire, with a electric heater used to control the temperature. After reaching a certain temperature, it is maintained at that level for a set period of time, after which the heat treatment is complete. It’s very simple. Qualified construction companies have the appropriate equipment, so it’s a very simple task for them.
