Thermal spray aluminium and thermal spray cladding provide dependable corrosion protection for pipelines and for tubes / waterwalls in boilers where high temperature corrosion and/ or erosion may occur. Thermal Arc Spraying, commonly known as metal spray coating, is a process by which metals are sprayed onto the surface of another material using a high velocity continuous combustion process. This process changes the pipe surface properties by providing improved thermal conductivity and wear resistance.
