The importance of security seals for valves

Reactors, boilers, storage tanks, pipes, and many other pressure devices, can be subjected to pressures higher than those of their design, with the corresponding danger of explosion.

To avoid this type of accident, which can cause serious consequences, the so-called safety valves are installed, which allow the excess pressure to be relieved by discharging the contained fluid.

Valves are therefore a security instrument widely used in industry and required by regulation, and which is made up of different elements, including seals. In this sense, what does the regulation say about its installation?

The NPT 342 good practice guide on the technical characteristics of safety valves talks about the importance of seals in different phases:

  • In the construction of the valves: it states that the design of the valves should include the installation of a sealing mechanism for the set pressure regulating body, in order to prevent unauthorized manipulation.
  • When assembling the valves: after checking that there are no leaks and carrying out the corresponding calibration, proceed to seal the set pressure regulator. If the conditions change, it will be unsealed, readjusted, and sealed again.

In addition, the technical sheet of the National Institute of Safety and Hygiene at work highlights the importance of sealing of the regulatory institution so that it cannot be manipulated by unqualified personnel.
