TPU oil bladder

Oil Bladder

TPU oil bladder tank is a heavy‑duty collapsible flexible storage container, manufactured from high‑strength TPU‑coated polyester fabric by high‑frequency hot‑welding process.

Different from one‑time‑use container flexitanks, TPU bladders are reusable soft tanks for temporary storage & short‑distance transportation of diesel, kerosene, lubricating oil and other industrial liquids. It can replace rigid metal tanks, greatly reduce transportation and storage space, widely used in mining sites, construction sites, offshore vessels, field engineering and emergency fuel reserve projects.
