General Inspection is the fundamental phase of the complete CNG cylinder testing process. The process begins by our experienced technicians taking the cylinder off the vehicle. Then, they perform an exact and carefully controlled discharge of residual CNG gas to ensure that the cylinder is gradually completely empty for safety in handling. This first step is crucial to ensure safety and allows the cylinder to be prepared for an extensive internal and external examination. This is not just a pre-check its the first step in identifying any potential problems and making sure that the next tests are carried out in a secure, solid, depressurized, and safe component. This approach makes sure that each cylinder is prepared to undergo a thorough evaluation and sets the benchmark for a safe and secure testing procedure that puts the safety of the technician and the vehicle owner over everything else.
General Inspection is followed by an extensive and thorough cleaning process designed for preparing the cylinder for a precise evaluation. After being empty, every cylinder is cleaned with a specific detergent powder that is of the highest quality. The main goal of this step is to remove all staining that is difficult to remove and, most importantly, excessive liquid oils that build up as time passes from the routine usage of CNG kits. This is not only for aesthetic reasons; its a vital test for diagnosing. After removing all traces of dirt and grime, we can reveal the true surface of the cylinder, eliminating any imperfections hidden like fractures along the hairline, corrosion, or pitting that could be hidden by dirt. A clean, clear surface is vital for an accurate technical and visual assessment prior to the cylinders progress into the hydro-testing stage of advanced technology.
General Inspection concludes with the most important diagnostic step, which is the structural integrity inspection. Once the cylinder has been cleaned and dried thoroughly, our certified inspectors conduct thorough examinations for indications of external or internal corrosion and rust that could weaken the cylinders structure. After this inspection the cylinder is subjected to the precise hydro-testing procedure. This process is extremely precise and exposes the container to high-pressure water to precisely measure its elasticity and to examine it for any signs of wear or loss of tensile stress, which is often unnoticed by people with no eyesight. The final, definitive test confirms that the cylinder is able to withstand the tensions of daily usage, assuring the structural integrity of the cylinder and providing you with assurance when you travel.
