Differences between single- and double-skin tanks
Single skin
Single-skin tanks and double-skin tanks are two different types of storage tank. Single-skin tanks are manufactured with a single layer of HDPE (high-density polyethylene). They are often used to store products at moderate temperatures and can be an affordable option for storing non-toxic products.
Double skin
Double-skin tanks, on the other hand, have an inner layer in HDPE and an outer layer in the same material. They are designed to provide additional protection for stored products, especially those that are toxic or corrosive. The double jacket also provides better thermal insulation to keep product temperatures stable, which can be important in certain industrial applications.
