Floating Agitator Repair
Some of the most demanding wear problems on our planet occur within the Oil, Gas & Petrochemical industries, where aggressive chemical corrosion and abrasion are an everyday occurrence, and where Welding Alloys have provided solutions for over 30 years.
Paddles are a part of agitators which are essential for the transportation of liquid suspended coal and the paddles constantly move the ingredients from one end of the tank to another. As a consequence, significant wear of these components occur during coal transportation, from the mine to the chemical company for the production of gas and other chemical products. This poses a major challenge and has become an area where Welding Alloys have built a reputation as global leader, in the provision of complete services within the Oil, Gas and Petrochemical industry.
After the initial meeting, Welding Alloys France’s technical team conducted an in-depth assessment and analysis of the paddles and the working environment to establish the best possible solution for the specific type of wear the paddles were facing. In the end, we proposed a hardfacing solution which would not only protect the paddle blades, but specifically focussing on the edges and the inside contours where they were most severely affected by wear.
Welding Alloys Integra services team recommended using one of our specialist Hardface chromium cast iron wires for the project. The weld metal is highly abrasion resistant thanks to the chromium carbide deposit and it features a hardness of 58-64 HRC, making it the perfect wire to protect the paddle blades, increasing component lifetime and reducing maintenance needed on the agitator going forward.
