Product overview
About this product.
Boiler tubes face heat, pressure and repeated temperature changes. UNIMETRA composite tubes combine a structural steel base with an alloy chosen for the exposed surface. Material selection takes account of steam conditions, flue gases, deposits and the way the equipment operates.
