What Are the Precautions when Using CNG Tanks?

CNG Tanks are professional products for storing liquefied natural gas, special equipment, Class III pressure vessels, 06Ni9DR material, manufactured after flaw detection, hydro-pneumatic test, on-site inspection by Technical Supervision Bureau, issuance of pressure vessel inspection certificate, external rust removal and painting.

Pipeline manufacturers are subject to extreme environmental conditions for fluid and pipeline transportation and therefore use special corrosion-resistant steel. This anti-corrosion steel requires a certain thickness, and manufacturers can start with preforms that avoid material loss by using metal spinning machine.Metal spinning machine manufacturer tells you the precautions for using LNG storage tanks.

1.gas cylinders should be placed in a well-ventilated place, and the distance between fire and heat sources should not be less than 1.5 m. Gas cylinders are strictly prohibited to be baked with fire, boiling water or exposed to the sun. To frequently check the gas tightness of the cylinder valve and pipeline joints, etc., to maintain no air leakage. Soap and water can be used to check the leakage, it is strictly prohibited to test the leakage with open flame.

2. ignition, should first ignite the ignition, and then open the gas, should not reverse this order. In the process of use, someone should watch and not leave to prevent the water from boiling over and extinguishing the fire, causing the liquefied gas to run away and cause an explosion. After using the gas cylinder, the valve must be closed tightly to prevent gas leakage.

3. The liquefied gas in the cylinder should not be used up, but should be left with a certain residual pressure. The residual pressure should generally be greater than 49.03kPa (i.e. 0.5kg/cm2, gauge pressure) to prevent air from entering the cylinder. After the LPG is used up, the residual liquid left in the bottle is also a flammable material and should not be dumped by itself to prevent the flow and evaporation of the residual liquid from causing a fire.

4. liquefied petroleum gas cylinder is a kind of pressure container, to be well maintained and regular inspection. In the handling and use of the process to prevent the cylinder from falling or impact, not allowed to open the valve with iron knocking, to prevent direct sunlight and long-term rain. Gas cylinders are generally inspected once every 2 years.

5.Although the explosion range of LPG is not too wide, but because of its small lower limit, so, once the leak is easy to ignite the explosion. And because LPG is heavier than air, so in the air leakage flow downward, good accumulation in low-lying areas, become a potential gas explosion. Therefore, the gas is prone to leakage. Only by the window ventilation is not enough, but also pay attention to the lower ventilation.

6.When a liquefied gas leak is found indoors, the doors and windows should be opened promptly for ventilation so that it spreads in the direction of no open flame, and no fire is allowed in the vicinity, and it can be used only after the trouble is removed and its characteristic smell disappears. The waste liquid leaking on the ground should be covered with sand and cleared to a safe place. When the gas cylinder is on fire, the valve should be closed immediately, moved to an open place outside, and put out the fire with dry powder extinguishing agent, carbon dioxide extinguishing agent or covered with a wet sack.

7.To educate children are not allowed to play with gas cylinders, users to understand the safety knowledge of the use of gas cylinders.
