The Square or Rectangular Fins H-Finned Tubes are the preferred tube choice for high pressure boilers.
Fins can be manufactured by stamping process in almost any shape and size.
In-line fin and tube spacing allows for cleaning with excellent choice in sooting or fouling atmospheres.
Fin height and spacing are limited only by heat transfer considerations.
Fins and tubing can be similar or dissimilar metals.
