Before filling: heating with the first step of the cylinder, the second step is to dry the moisture inside the cylinder, the third step to open the cylinder calabash valve pumping air into vacuum state, the fourth step play 0.3 to 0.5 mpa raw material gas chromatography to test, test impurities, this step is to test both sides can enter the next step aeration process..pay attention to that before use, please open a little bit of the valve and blew the ash off the valve and piping on the grey, because impurities affect the purity of bottle.So far our products are enjoying good markets at home and exporting to European and American countries, the Middle East countries, West Asia, as well as South and East Asia countries.Specification of High PressureGB5099 Standard or ISO9809TypeOutside Diameter Do.(mm)Water Capacity (L)Height(without valve) (mm)Weight(without valve cap)W(kg)MaterialStandardWMA108-1.4-151081.42382.9637MnGB5099-3WMA108-2-151082.03203.75WMT108-2-151082.03173.72WMA121-3.2-151213.23905.02WMT121-3.2-151213.2385.84.98WMA121-4-151214.04856.16WMT121-4-151214.04705.95WMA140-4-151404.03725.77WMA140-5-151405.04587.52WMA140-6.3-151406.35248.72WMA140-7-151407.05939.84WMA140-8-151408.067110.72WMA140-10-151401084513.4WMA152-7-151527.05289.57WMA152-8-151528.060010.66WMA152-10-1515210.072612.6WMA159-10-1515910.068514.15WMA159-12-1515912.080016.34WMA159-15-1515915.097519.66WMA219-20-1521920.073029.00WMA219-40-1521940.0131048.00WMA232-40-1523240.0122050.00WZA232-47-1523247.0136051.00WMA219-50-1521950.0160057.00WMA232-50-1523250.0138065.00IWGA219-40-1521940.0138052.0034CrMo4ISO9809-1IWGA232-40-2023240.0117052.00IWGA232-47-2023247.0136055.00IWGA232-50-2023250.0144056.00Note:1.WMA-Concave Bottom WMT-Convex Bottom2.
