The difference between heat exchange tubes and boiler tubes

Boiler tube: part of the boiler’s pressurized circulation system; the core issues arecreep strength at high temperature, microstructural stability, and pressure-containing safety.

Heat exchange tube: a heat-transfer element in heat exchangers/condensers/preheaters; the core issues areheat-transfer efficiency under thin-wall conditions, service life under medium corrosion, and sealing integrity.
