Pickling chains, utilized in galvanizing plants, serve as crucial components designed to securely hold steel items destined for galvanization. These chain slings facilitate the dipping process into baths of acid, often maintained at elevated temperatures ranging from 435º to 455ºC. Despite enduring harsh chemical environments and intense heat, these chains must retain their heat resistance and operational efficiency. Therefore, regular inspections are imperative to guarantee their continued integrity and suitability for the intended application.
Depending on the object intended for lifting, galvanizing plants typically necessitate diverse types of chain slings, equipped with various fittings, specifically designed for lifting and transporting components destined for galvanization. Standard-grade chains are unsuitable for this task. Instead, the chains and components employed in the hot-dip galvanizing industry adhere to grade L specifications, representing a low-carbon steel chain with the lowest tensile strength. These chains are suitable for hot-dip galvanizing and are frequently utilized by boat builders due to their superior resistance to corrosion and abrasion in severe environments.
Regular inspections of this product are vital, and in the event that there is suspicion that the chain has been exposed to a chemically active environment, it is necessary to immediately withdraw the item from service.
