Drive in at your time and leave with a stamped cylinder and certificate.
Each centre runs five slots a day with a fixed cylinder capacity, so your vehicle is never kept waiting.
Scroll through the eight checks every cylinder passes before it gets a fresh stamp.
We record your vehicle number, RC and the cylinder's serial number, manufacture date and last test stamp.
Remaining CNG is vented safely, the cylinder is unbolted and the valve removed.
Inside and out, we check for dents, cuts, corrosion, bulges, fire damage and thread wear.
The cylinder is filled with water and placed in a water jacket, so the test itself is completely safe.
Pressure rises to 1.5× the 200 bar working pressure and is held while stretch is measured.
After release the cylinder must return to shape. Too much permanent expansion means it fails.
The cylinder is dried, the valve refitted to the correct torque and leak tested.
The new test date is stamped and you get a certificate valid for the next 3 years.
CNG cylinders must be hydro tested every 3 years. Enter the month stamped on your cylinder.
