3. LNG Tank Fault Inspection and Handling 3.1 Daily Inspection

3.1.1 Level gauge and pressure gauge operation check.

3.1.2 Are the shut-off valves, regulating valves, and safety valves in normal working condition?

3.1.3 Tank, piping, and valves for any leaks.

3.2 Regular Inspections

3.2.1 The pressure gauge should be calibrated annually and accompanied by a certificate of inspection with a lead seal.

3.2.2 The safety valve should be calibrated annually and sealed with lead.

3.2.3   Liquid at low temperatures should be analyzed every three to six months as required for operation.

3.3 Fault Handling

Occurred malfunction

Original Cause

Processing Measures

1 Abnormal inner cylinder pressure

Increase or Decrease

A Pressure Gauge Distortion

B tank vacuum reduced

Operation error with valve C

A Pressure Gauge

B vacuum extraction

C meets the manual operation requirements

2 Level Gauge Distortion

Improper operation of the level gauge valve

The B level gauge is damaged.

Reoperate as per requirements.

Replace with a new level gauge

3 Chiller Tank External Frost Accumulation

Vacuum Failure

B-laminate leak

C Color Pearl Sand Sink

A re-evacuate the vacuum

B pressure test and leak check, then evacuate air

Please re-install pearl sand in the C-type balanced sandwich and then vacuum it again.

Note:

1. If the user needs to evacuate or re-fill the interlayer with pearl sand, they must first empty the inner cylinder's liquid and wait until the inner cylinder returns to room temperature before proceeding.

2. Should users encounter difficult-to-handle issues, they may promptly contact our after-sales service department. We offer a three-package quality guarantee for our products. We also provide repair services for products beyond the warranty period and for non-our company products.

4. Cautionary Notes

4.1 The vacuum valve is sealed before the product leaves the factory. After the storage tank is delivered to the customer's site, the customer must ensure the protection of all pipeline valves during installation, particularly the vacuum valve, and strictly prohibit any collision or opening of the vacuum valve.

4.2   Do not empty the liquid in the tank unless it will be unused for an extended period. This is to prevent the inner cylinder from overheating, which would require re-cooling when refilling, resulting in unnecessary losses.

4.3 Low-temperature liquid storage tanks are used for storing liquid nitrogen, liquid oxygen, and liquid argon. However, when switching to another liquid, the original liquid must be completely drained and the tank purged before refilling with the new liquid.

Note:

1. The fill valve opens when the liquid is nearly full, closes when liquid starts to flow, and stops the inflow. For the first filling, it should be done from the top first, followed by the bottom.

2. Open during the discharge of residual liquid.

3. Open the vent valve when the container pressure is too high.

4. The container automatically opens when over-pressurized. Normally, only one is used. If the working one fails, the other is immediately activated to ensure the safe operation of the storage tank. The damaged safety valve is then repaired and calibrated, and promptly reinstalled upon passing inspection.

5. The inner cylinder automatically starts upon opening the boost valve when the need for pressurization arises.

6. The level gauge is often turned off during normal operation.

7. Burst upon overpressure; immediate replacement required after bursting.
