ISLAMABAD: All the CNG vehicle owners have been asked to use certified CNG cylinders and kits in their vehicles and get them tested from trained personnel after every five years.
An official of Oil and Gas Regulator Authority (OGRA) also advised the owners to get their vehicle's CNG system inspected at least once in a year from a trained technician.
Compressed Natural Gas (CNG) is a high-pressure gas for which specially designed and fabricated seamless cylinders manufactured in accordance with prescribed standard should be used in vehicles.
Only the valid licensees/CNG Stations have been authorized to convert vehicles to CNG at their respective facilities.
The Authority has asked both public and private vehicle owners to use only approved brands for their own safety and interest.
LPG, Oxygen, Nitrogen, Acetylene cylinders are not meant for the CNG use so that never use these cylinders as they cannot withstand CNG pressure of 200 Bars and therefore will explode causing loss of life and property.
The owners should not get installed CNG kit/cylinder in the vehicle from any unauthorized or a road-side conversion workshop/outlet.
"Never install a cylinder which has been fabricated by joining two halves by means of male and female threads or welded as only seamless vehicle cylinders are used for CNG," he added.
The owners should not install a used cylinder which has been burnt/damaged during riots or other terrorist activities. Such cylinder is weakened and may lead to serious accidents resulting in loss of precious lives.
The owners of vehicles should never ask for refueling beyond the allowable maximum pressure of 200 Bars under any circumstances.
In case any CNG station is found dispensing CNG at excess pressure, it may be reported to OGRA for strict action against the station to ensure public safety.
The owners were further advised to get CNG cylinder test certificate from the CNG licensee after conversion of vehicle to CNG and also get vehicle's CNG system inspected at least once in a year for examination of the cylinder, piping, CNG kit, all components, leakage testing as well as performance of the CNG system to ensure its safe operation.
People should not smoke during refueling in the vehicle and ensure that the CNG cylinder installed in the vehicle is within the periodic test life, which is five years.
In order to determine the validity of the cylinders, the nearest CNG station or nearest Hydro Carbon Development Institute of Pakistan (HDIP's) office may be approached for the purpose.
In case the cylinder requires testing, the HDIP testing labs at Islamabad, Lahore, Karachi and Peshawar should be contacted.
