A series of cleaning steps are required on the surface of the cylinder and the inside of the cylinder before it is activated.Inside the bottle bottles, wrapped in the cleaning equipment, cleaning with 18 to 27 ℃, the minimum flow rate is 4.5 litres/minute Lenium GS (n - bromine propane) wash bottles within three minutes, and then out of the bottle of detergent.Use clean oil free dry hot air blow dry bottles (82-93 ℃).The hydrocarbon pollution in LNG cylinders must be less than 1 mg/m2.Check that the inside of the bottle is odorless and pollution-free.

2. Basic parameters of cylinder cleaning equipment

1. Processing cylinder diameter: ￠219 - ￠426 mm

2. Cylinder height: 600-2000mm

3. Power: 2.2kw

4. Pressure of air source: 0.8mpa

5. Number of stations: 1

6 dimensions 1200 by 1400 by 2100mm

3. Characteristics of gas bottle cleaning machine equipment

1. Equipped with adjustable center height adjustment device.

2. Suitable for different cylinder cleaning. 

4. Compressed air clamping mode.Place the cylinder around.

After cleaning the gas cylinder can basically meet the test specification, then the next step detection procedure is carried out. The test procedure of the LNG cylinder detection equipment is as follows:

Bottle of registration - cylinders on line - nitrogen replacement to discharge valve, the internal cleaning to add plug cylinder surface derusting, discharge plug (cylinder) to appearance inspection, wall thickness determination to sound check - bottle thread inspection, internal inspection, NDT inspection (cylinder) - empty bottle weighing, and data automatic transmission to industrial water, joint on special spin - full bottles of weighing, automatic data transmission to the industrial computer to tighten the water jacket cover, loosen the bottles to swing cylinder into the water jacket, automatic pressure tight seal water jacket cover and compression experiment (computer control) to loosen the water jacket cover, screw cylinder out of water jacket and water casing to overturn water, dry to install cylinder valves, air test - scroll to exhaust nitrogen charging zone - connection flow discharge gas pressure relief (residual air recycling), nitrogen to remove the cylinder to checked bottle filling pile area
