IGEM/UP/1a Edition 2, Strength Testing, Tightness Testing

IGEM/UP/1A, Edition 2, Strength testing, tightness testing and direct purging of small, low pressure industrial and commercial Natural Gas installations.

Section 2:

Scope 2.4 states that the document procedures apply in relation to the following (amongst others areas):

“Where there has been a complete loss of pressure for any reason, note, The closure of a valve, for example, the ECV, can result in the complete loss of pressure which necessitates tightness testing and purging before resumption of supply”

An explanation of the above in relation to gas pressure proving.

Referring to the words “can result in the complete loss of pressure”. When a solenoid or other type of ECV closes for whatever reason if a downstream boiler, appliance or Bunsen burner is switched on then the gas pressure will be lost.

This is likely to happen particularly where flame safety devices are fitted.

The difficulty with installations in a normal commercial environment where there are no qualified engineers or technical staff on site, is that the lay person for example the lab technician or caretaker may not be able to ascertain whether the gas pressure has been lost. 

The incorporation of an automatic gas pressure proving system can overcome this uncertainty.

This is fitted in conjunction with the gas solenoid valve and allows the operator to simply reset the gas pressure proving system so that a downstream integrity test is automatically carried out before the gas supply is restored.

The downstream integrity test (gas pressure prove) is used as a measure to confirm the integrity of the system either to negate any leakage or, if confirmed, warrant investigation and repair.

Further reasons for the use of gas pressure proving systems can be found in this standard IGEM/UP2, Edition 3.
