Cleaning Techniques For CNG Cylinders
Aug 07, 2017


The cleaning method of CNG cylinder, take a look below.

1, the use of aqueous solution (sodium silicate solution) or alkali solution washing, CNG cylinders should be dried immediately after cleaning.

2, the use of solvents to remove the internal wall of CNG cylinder pollutants, almost all carbon-based pollutants, can be liquid water soluble or organic solvents washed out.

3, the use of a good alkaline solution of the vapor spray gun, CNG Steel Cylinders inserted into the bottom of CNG cylinders, injection into the alkali solution 15~30min, the solution from the CNG cylinder overflow will be removed from the pollutant. CNG cylinders contaminated with oil or hydrocarbons, more than 90% per cent of pollutants, can be treated cleanly with organic solvents, but cannot be washed with carbon tetrachloride because it is a highly toxic solvent. After cleaning, you must dry and plug the bottle.

Although the use of CNG cylinders is convenient, but there are also unsafe hidden dangers. In case of pipeline leakage or valve is not tight, gas to the indoor diffusion, CNG Steel Cylinders when the content reached the explosion limit, encounter Mars or sparks will explode. So what are some of the problems we should pay attention to in the daily use of CNG cylinders?

① should be used in a separate brick-and-tile kitchen to properly place liquefied petroleum gas (LPG) equipment.

②CNG cylinders must be placed upright and not allowed to lie or lay down. CNG Steel Cylinders Must be diligent inspection, fine observation, find the problem timely treatment. For safety, please turn off the CNG cylinder angle valve before you go to bed.

③cng cylinders must be away from the heat source, placed in easy to move around, no flammable, more ventilated place, the stove, bottle distance above 80 centimeters, not in any form to the CNG cylinder heating.

④ installed before the valve to check the sealed rubber band, do not have variant, defect, installed pressure valve handwheel to the valve mouth, counterclockwise rotation to tighten.

⑤ rubber HOSE, cooker switch, pressure reducing valve and hand wheel to the cylinder valves connection part is more easy to leak, check the leak please use soapy water brushing inspection parts, do not use the fire to check the leak. In the event of a fire to cut off the gas source as soon as possible (close the bottle valve), CNG Steel Cylinders do not put the bottle, and timely report to the fire.

⑥ No unauthorized demolition, conversion of liquefied petroleum gas special equipment, there are problems please supply units to deal with. The leakage of liquefied petroleum gas should be timely closed the bottle valve, open doors and windows, ventilation evacuation. In the leaking site, all types of open flames (including cigarette butts) are prohibited from opening, closing all types of electrical equipment.

In order to remind people of the leakage of liquefied gas in time to prevent accidental occurrence, CNG Steel Cylinders processing plants in the factory before the gas often mixed with a small amount of odor of mercaptan or sulfur ether compounds. Once the liquefied gas leaks, smell the odor immediately. and take emergency measures.
