The 5-Step PESO Hydrostatic Testing Procedure

Standard operating procedure prescribed by PESO (Petroleum & Explosives Safety Organisation) for CNG cylinder re-certification:

Step 1: Degasification Residual CNG is safely purged through nitrogen blanketing to ensure zero volatile vapors remain inside the vessel.
Step 2: Internal Inspection An endoscope camera inspects the interior vessel walls for pitting, corrosion, or hairline micro-fractures.
Step 3: 330 Bar Hydro Test The cylinder is submerged into a water jacket and pressurized to 330 Bar (1.5x working pressure) to measure permanent volumetric expansion.
Step 4: Tare Weight Check The cylinder is dried and weighed. If wall thinning exceeds 5% of original manufacturer tare weight, the cylinder is condemned.
Step 5: Collar Punch & Stamp A metal compliance plate is affixed to the brass collar with the test date and center code, and a digital QR certificate is uploaded to Parivahan.
