The primary purpose of any rail tank car is the transportation of liquid, powdered, gaseous, or solid cargo.

When configuring the rolling stock according to the specific characteristics of the cargo being transported, its properties, and the requirements for storage and transportation conditions, the tank’s calibration type, design, and intended use are taken into account. In all cases, however, the design includes sealing rings that ensure a tight seal between the hatch and the tank body.

In addition to reliably preventing leaks during cargo transportation, sealing rings effectively protect the tank from moisture and precipitation. This ensures the safety, quality, and original properties of the cargo throughout the entire transportation process. To maintain this level of protection, rolling stock owners carry out regular maintenance and replace tank sealing rings in a timely manner.

What is a tank ring?

Rubber rings are the most widely used solution for ensuring tank tightness when the hatch is closed. Acting as a reliable sealing element, they are installed on the tank car’s discharge unit and provide secure protection against leaks and external influences. These rings are typically manufactured from high quality rubber, making them durable and effective in demanding operating conditions.

The following key advantages of using tank rings are worth noting:

  • ensure full compliance with current sanitary standards, making them suitable for a wide range of cargoes;
  • are made from durable material with high wear resistance, ensuring long service life;
  • offer an optimal balance between quality and cost, remaining an affordable solution;
  • thanks to their structure, do not absorb liquids or odors, allowing the same seal to be used for transporting different goods without affecting their properties;
  • high elasticity allows the rings to quickly recover their original shape even after repeated loads and deformations.

At the same time, installation is quick and straightforward, requiring minimal time and effort from personnel servicing mobile storage facilities.
