Technical data – Steel Fin tubes

Technical information

Resistance-welded rectangular steel fin tubes are normally used in economisers and flue gas coolers for solid fuel boilers or other industrial applications involving dust-laden gases.

The straight in-line design makes maintenance and cleaning simple and efficient.

Ekströms offers both single and double steel corrugated pipes in a wide range of dimensions.
