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. |
Fusion bonding is a special coating mechanism that totally differs from painting. Resin is used to create the additional layer and the process of application requires expertise and special equipment. The application surface and liquidized powder must be heated to appropriate temperatures if the desired results are to be achieved.
The process of cross-linking is a chemical reaction and cannot be reversed. The coating will not melt again under natural heat. The process is otherwise referred to as thermoset coating. The thickness of application will depend on intended use for the pipe. It can range from 10 to 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.
Depending on the use, some pipes will need both internal and external coating. Internal coating ensures reliable passage of petroleum, water, gas, sewage and other substances. Some production plants, oil refineries, paper mills and power plants need specialized piping. Regulations require water pipes and pipes transporting food items to be specially prepared.
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.
