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.

Boiler Material - IBLS

2018-7-20·The big advantage of the use of this material is the wall thicknesses can be about 1/2 as thick. The material is almost twice as strong as mild steel and no extra thickness allowance need be made to allow for corrosion in the boiler through use. The material they are talking about is ASTM A240, A276, A789 and A790 (depending on the application).

What are the various types of tubes used in water tube

2010-8-3·Water Wall Tubes. These are used basically to contain the heat of the furnace, thus reducing the amount of refractory material required. In some types of boilers, water cooled refractory cells are used. These consist of tubes with studs welded onto them, covered with refractory material, which can now withstand the high temperatures without damage.
