Product Description
SA-210C Carbon Steel Bare Tube Boiler Economizer Coil
Usage and Application
The SA-210C bare tube economizer is a critical energy-saving pressure part installed in the low-temperature tail flue of utility and industrial boilers. It recovers residual heat from the exhaust flue gas and uses it to preheat the high-pressure feedwater before it enters the steam drum or water walls, lowering fuel consumption and raising overall thermal efficiency.
Manufacturing Capability
- In-house CNC tube bending held to ±1 mm over the full coil length
- Submerged-arc welded (SAW) headers qualified to ASME BPVC Section IX
- Automatic circumferential welding for leak-free tube-to-header joints
- 100% radiographic examination and hydrostatic pressure testing before shipment
- Full material traceability with mill test certificates (EN 10204 3.1)
Material Specification
The coil is fabricated from SA-210C carbon steel seamless tubes, a fine-grain boiler quality material with excellent strength and weldability. Alternative carbon, low-alloy and ND steels are available on request for specific flue gas conditions.

Custom tube diameters, wall thicknesses, fin types, header layouts and coil configurations are all available to match your project parameters.
Frequently Asked Questions (FAQ)
Can you fabricate economizer coils to our engineering drawings?
Yes. We manufacture strictly to client drawings and national standards, and our engineering team can also propose optimized tube layouts if you provide the boiler parameters.
How do you guarantee the leak-free quality of tube-to-header joints?
Every header joint is automatically welded and then checked by radiographic examination and hydrostatic testing, and a full test report is issued with the shipment.
What is the typical lead time for a custom economizer coil?
Production normally takes 30 to 60 working days after deposit, depending on coil size, material grade and the required testing scope.
