Know your Linings

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.

What makes ‘Food Grade’ stainless steel safe?

Just like academic grades, the particular ‘grade’ of stainless steel refers to how it measured up against a variety of tests and requirements. However, in the case of stainless steel, these measurements refer to its quality, durability and temperature resistance. Food grade stainless steel is steel that met all criteria to be deemed safe for food preparation, storage and dining.

The most common food grade stainless steel is Type 304. But 304 grade stainless steel also goes by another name or code, 18/8 and 18/10 stainless steel. These numbers refer to the composition of the stainless steel; the amount of chromium and nickel in the product. Both 18/8 and 18/10 contain 18% chromium, and 8% or 10% of nickel respectively.

304 grade stainless steel is so popular in the food industry because of its resistance to oxidization and corrosion. The chromium protects the product from oxidization or rust, whereas the nickel content rescues the food grade drum from corrosion. The higher the nickel content, the more resistant the stainless steel is to corrosion.

Stainless steel has become one of the most common materials found in kitchens and the food industry today. From food processing plants to large, commercial kitchens to your own kitchen at home, stainless steel is ever present. It’s corrosion and oxidization resistance paired with durability and how easy it is to clean has made stainless steel one of the safest materials in the food preparation and storage industries. In addition to resisting various acids found in meats, milk, fruits and veggies, there are also no chemicals within type 304 stainless steel that can migrate to your food, making it a safe, strong and durable choice for appliances, dishware, utensils, food storage and more.

When it comes to safety, Skolnik’s type 304 stainless steel makes the grade.
