Clad/Lined & Pressure Vessels
Strip & Fusion Bonded Cladding (prelim)
Vessels can be manufactured and supplied with an internal lining known as Strip Cladding.
Strip cladding can be supplied in various widths but commonly supplied between 20mm and 70mm wide.
Strip cladding is a fusion welding technique used to deposit a strip of weld metal onto a component to achieve metal build up or to provide a corrosion resistant surface.
For example a Carbon steel vessel can be supplied with a corrosion resistant surface of stainless steel for use in a corrosive atmosphere at high temperatures.
Strip cladding is an economical way of achieving the above, instead of the high cost of using thick stainless steel vessels.
Not only can cladding take place within the vessel shell, but also on flange faces where large flanges can become uneconomical to use.
Vessels that are usually clad lined are used in hydrogen containing environments in the petroleum industry in hydro-cracking, hydro-desulphurisation and catalytic reforming processes.Reactor vessels are also brought under this category, which usually operate at high temperatures with high hydrogen particle pressures, and are usually fabricated from low alloy steels which need protecting internally from high temperature corrosion.
Where strip cladding is not permissible, materials can be purchased with the stainless steel material is already fusion bonded onto the low alloy steel, before any forming or fabrication has taken place. Great care is to be taken when rolling or forming processes are carried out on this material.
Other forms of lining can be offered by Flaretec when the process is not as severe, such as Glass Flake lining, rubber lining (soft & hard), and also a general internal paint system can be offered.
