【Test items】

The gas cylinder pressure cycle test stand is a special gas cylinder testing equipment designed and manufactured according to relevant national standards. It is mainly used for pressure fatigue strengh and life simulation fatigue test of LNG gas cylinders, CNG gas cylinders, LPG gas cylinders, breathing gas cylinders, wound gas cylinders, nitrogen cylinders, oxygen cylinders, accumulator and fire fighting bottle. The equipment is widely used in gas cylinder production plants, product quality inspection institutes, research institutes and other units to test and develop production of various gas cylinders.
