Waterwall Boiler Panel Cutting - Made in Germany

In maintenance of industrial high pressure steam boilers panel wall cold cutting is an important step before weld preparations. To avoid any heat affected zone (HAZ) on the boiler tubes of the water wall panels, the sawing of the defective panel wall tubes should be done not by flame cutting but instead with the BWC cutting system, that uses abrasive saws.
