Once winter sets in, temperatures drop rapidly and valves often freeze. If left unaddressed, this can easily lead to pipe failures. In high-risk operating conditions, it may even result in accidents. Therefore, frost protection for valves is of the utmost importance.
Before temperatures drop, a comprehensive insulation job must be carried out on the valve assembly to ensure it is properly ‘winterised’.
Gather the necessary tools: insulation wool, wire, pliers, a craft knife, and, in gas-using areas, a working gas detector.
Cut the insulation wool to size using the craft knife, taking the valve’s dimensions into account. Use the pliers to cut lengths of wire for securing the insulation. When wrapping the insulation, tear a small section to allow it to wrap around the valve handle, ensuring the valve body is fully covered. Once the insulation is in place, secure it with the wire.
If, during use, you find that the valve has frozen and is not functioning properly, never strike the valve with a spanner or other heavy object. The correct procedure is to close the valve, thaw it using steam or hot water, and then reopen it.
If the valve is not to be used for an extended period, the medium within the pipeline must be completely drained to prevent the pipeline and valve from freezing. Ensuring safe production is the duty and responsibility of every enterprise. Valve frost protection is a matter of great importance; we must not allow a momentary lapse in attention to lead to an irreversible situation.
