### Q: What are the main applications for steam headers in machinery manufacturing?
**A**: Steam headers are essential in industrial systems for collecting steam from multiple boilers or sources and distributing it to various equipment like heat exchangers, turbines, and process heating systems, ensuring efficient steam management and pressure control.

### Q: How do I choose between carbon steel and stainless steel for a steam header?
**A**: Carbon steel is cost-effective and suitable for standard steam applications with moderate temperatures and pressures, while stainless steel offers superior corrosion resistance and durability for high-temperature, high-pressure, or corrosive environments, making it ideal for demanding industrial settings.

### Q: What safety features should a steam header include?
**A**: A properly designed steam header must include safety valve connections to prevent overpressure, pressure gauge connections for monitoring, isolation valves for maintenance, and drain connections to remove condensate, ensuring safe and reliable operation in industrial systems.
