Small Diameter Cold Drawn Seamless Metal Tubes ASTM For Water Wall
Usually laid on the inner wall of the furnace, mainly used to absorb the flame in the furnace and high temperature flue gas released by the radiant heat.
Because of the role of cooling and protection of the furnace wall, the water wall pipe is vertically arranged in the furnace around,
its main role is to absorb a lot of radiation heat of high temperature flue gas,
at the same time can reduce the slag and high temperature flue gas damage to the furnace wall, protect the furnace wall.
