Carbon steel and stainless steel each possess properties that make them perfect containers for specific materials without any modification. But, for some materials, especially in the pharmaceutical, chemical and food industries, a drum lining is necessary. Lining is often required as a safety precaution, to meet the strict regulations of government agencies, and/or because the contents or environment would be contaminated without it. Even as a precaution, lined steel is a necessary measure to preserve the integrity of the materials, container, facility, handlers and the environment.
The most common lining for a lined steel drum is a phenolic coating. Phenolic linings provide a chemical protection between contained materials, such as food, and the metal of the drum. The phenolic is mixed with an epoxy to give it extra flexibility – this prevents it from cracking if the drum undergoes any damage. Skolnik lined carbon steel also includes a rust inhibitor to remove surface oil prior to lining. The upper tolerance for Skolnik’s epoxy phenolic lining is about 550 degrees Fahrenheit, after which the coating could become brittle and compromised.
A rust inhibitor will prevent flash rust on our unlined/uncoated drums, but if a customer needs a long-term rust resistant drum or a drum that can safely contain chemical materials, an unlined drum will not suffice.
Skolnik lined steel drums are available in a variety of different shapes, sizes, materials and lining compositions. We recommend talking to one of our sales representatives if you have any questions about your container needs, lining needs or your materials compatibility with linings.
