Economizer Tube – Seamless Carbon Steel
For Boiler Economizer Service – Heat Recovery
OD 6mm – 204mm | WT 1mm – 18mm | Cold Drawn
Product Overview
Our economizer tube is a seamless carbon steel tube specifically designed for the economizer section of boilers. The economizer pre-heats feedwater using waste heat from flue gas, improving overall boiler efficiency by 5-8%.
Manufactured by the cold drawing process, these tubes are designed for moderate temperature service (up to 400°C) and offer good corrosion resistance to flue gas condensation.
Key Features:
Moderate temperature service – Up to 400°C
Good corrosion resistance – Suitable for flue gas environment
Cost-effective – Economical carbon steel material
Seamless construction – No weld seam – no leak risk
100% hydrostatic tested – Guaranteed integrity
Full traceability – EN 10204 Type 3.1 MTC with heat number
✅ Seamless construction – Pressure integrity assured
✅ Good weldability – Low carbon content
✅ Flue gas corrosion resistant – Suitable for economizer service
✅ 100% hydrostatic tested – Guaranteed integrity
✅ Factory direct | Global shipping
