Prevent Corrosion Using Fusion Bonding

102 4
Fusion bond uses liquidized powder to protect steel pipes from corrosion. This ensures that the metallic surfaces are ready for concrete reinforcing, valves and pipeline networking over harsh environmental conditions. The metal will end up with one or several layers depending on the purpose of use and technology applied.

There is a clear different between normal painting and fusion bonding. A special mechanism is used in applying the additional layer and a substance called resin. Special application equipment ensures that a smooth even coating is achieved. The metal and the surface of application are heated to substantially high temperatures to create the right condition.

The bonding process is a chemical reaction that is irreversible. This ensures that the coating does not melt away in future when subjected to further heating. The process is expertly referred to as thermosetting. The coat will be thick depending on the nature of the material and level of coating. This thickness can range between 10 mils and 40 mils.

The metallic surface is heated before liquidized powder can be applied. Application takes the form of a spray or total submerging in the liquidized powder. Consistent heating is best done in a specialized oven that has been standardized to ensure reliable results. It takes technical expertise, right equipment and experience to achieve an even coat.

Application is done on the outside and inner surface depending on the intended uses. This ensures that water, gas, petroleum, sewage and other liquid substances are easily transported. Special treatment is required for pipes dealing with drinking water and food items. Refineries, paper mills, power plants and other production units also require specially prepared pipes since they deal with chemicals and other hot substances.

All impurities must be removed before the special coat is applied. The surface is blast cleaned to remove any foreign particles. Spraying is done using an electrostatic gun that is automated to achieve an even and smooth coat. The coat is permanent and dries in minutes.

The purpose of use may necessitate a single layer or multiple layers. ARO is easily combined with FBE to form a dual layer on the pipe. The pipe may be protected from UV using a third FBE layer. The input of an expert technician is required when deciding on the thickness and number of layers to be applied on each pipe.

Dual coating is suited for heavy duty pipes that are to be used in flow lines and undersea connections. This prepares them for harsh weather and environmental conditions including rough transportation and installation. The surface is considerably flexible and can withstand harsh treatment without damage.

Some piping systems will require FBE rough coating. The resulting surface is not smooth and is perfect for concrete application. The concrete holds on the surface easily creating a tight bond. The two surfaces will not separate after drying. This method of treatment is perfect for pipelines that will combine with other construction surfaces and facilities.

Extensive research has been carried out during development of fusion bond to ensure maximum protection for all metallic surfaces. It ensures that there are no reactions with the liquids transported across. The pipes retain perfect conditions for years though they are buried deep in the ground.
