Reduced downtime, less maintenance, and maximized production efficiencies are critical components in protecting profitability for today’s manufacturers. Wire mill and wire drawing operations can manage these factors more effectively by assuring they’re using the highest quality pickling hooks in their pickling process.
The Alloy Engineering Company (AECo) brings more than 40 years of experience and reliable pickling hook production to the table for our customers. Expertly engineered alloy hooks, designed and manufactured by AECo, can last up to 10 times the life of carbon steel hooks.
We begin by working diligently to understand our customer’s process. We analyze your pickling bath acid concentration, bath temperature, tank size, hook load, and current failure modes. Next, we develop a strategy to enhance your process and maximize the productivity life of your pickling hooks. Each hook is specifically designed for the requirements of its application. We take into consideration the frequency of use, the load to be carried, and the dynamics of the system, including side loads.
The repetitive emersion of carbon steel pickling hooks in often unstable nitric acid or sulfuric acid baths contributes to their rapid erosion. Pickling lines designed to operate at an ambient temperature (75 F) seldom remain at that temperature. The exothermic reaction inherent in the pickling process commonly raises the bath temperatures above 100 F. Indeed, in some applications, the pickling line temperature is raised to 140 F to reduce the cleaning and coating cycle time which can significantly increase the corrosion rate of carbon steel hooks.
In some cases, AECo is able to repair existing hooks and extend their life. We can undercut the corrosion behind the weld and grind and repair them to extend their production life. Most often, we are able to demonstrate a greater ROI by replacing those hooks with our highly engineered alloy hooks.
AECo pickling hooks are actually lighter, yet stronger than carbon steel hooks. We fabricate them by welding sections to form an “I-beam like cross section” to maximize strength, which actually enables us to minimize material usage, making them lighter. The lighter weight minimizes risks and increases the safety factor. The weld preparation in our ASME certified plants also contributes to their superior quality and enables us to provide the best possible fabrication available.
We use engineering software to custom-design each hook based on your required service conditions. Years of experience and supportive data enables us to select the optimum material for each application. We encourage you to visit our website to learn more about our pickling hooks and study the material selection guide and design data there: http://www.alloyengineering.com/products/pickling-hooks.
The corrosion-resistant characteristics of AECo pickling hooks are also predictable, so they are minimally affected by changes in bath temperature or acid concentration which contributes to the longevity of our hooks.
Time after time, we’re able to demonstrate that the cost benefit of our pickling hooks far outweighs the expense of using, repairing, or replacing carbon steel hooks over time.
The Alloy Engineering Company has built a strong reputation throughout the world for our thoughtful and strategic approach, product reliability, and customer-centric service across all product and service lines, and most assuredly in the fabrication and performance of our pickling hooks.
