II. Description of Equipment Features, Performance, and Structural Parameters

1Equipment Features

Liquefied Natural Gas (LNG) storage tanks are of horizontal, double-walled cylindrical vacuum powder-insulated structure, with the inner cylinder containingLNGMaterial isS30408The head is made of a standard elliptical head, with the outer cylinder facing the atmosphere, material used isQ345RLow-alloy steel, an eight-point support structure is used between the inner and outer cylinders. Insulation thickness250mmThe inner and outer tube cavities are filled with thermal insulation material Pearl sand insulation material and vacuumed, with the pressure of the inner and outer shell cavities being absolute pressure ≤5PaThe vacuum level at the factory exceeds national standards, ensuring the evaporation rate indicators; the storage tank is equipped with a complete set of operation valves and instruments. These valves and instruments allow for on-site observation of liquid inflow and outflow, as well as pressure and level.

2Performance and structural parameters

Liquefied Natural Gas (LNG) storage tanks consist of the tank body, instruments, pipelines, valves, etc. These tanks are equipped with two types of liquid intake methods, upper and lower, which can be selected and used according to actual conditions.

The inner tank of the Liquefied Natural Gas (LNG) storage tank is equipped with a safety system consisting of dual safety valves. Under normal operation, one set is in operation while the other is on standby. If the operating safety valve trips, the manual pressure relief valve is immediately opened to depressurize below the tank's maximum working pressure. Simultaneously, the safety device is swiftly switched to the standby system via the manual handle, effectively ensuring the tank's safety. This safety system is composed of safety valves, explosion-proof devices, vent valves, and three-way ball valves, which not only reduces pipeline welding but also features excellent fire and static electricity prevention structures. Additionally, the safety relief openings on the housing are fully guaranteed to ensure the entire equipment's safety and reliability. The low-temperature pipeline is centrally extracted for ease of operation and control, and the extraction point is designed with a Dura tube structure to meet low-temperature requirements and minimize stress on the pipeline due to thermal expansion and contraction, ensuring the tank's safety. The vacuum pump valve is equipped with three stages of...OFormed ring seal ensures reliable interlayer sealing, made entirely of stainless steel with a compact size. The top design of the liquefied natural gas tank features a suspension structure for easy transportation, lifting, and installation. The unique manhole design ensures internal cleanliness when the container is sealed. Vacuum isolation valves and combined vacuum gauges are used on the liquefied natural gas tank for easy measurement of the interlayer vacuum level and maintenance, extending the tank's lifespan and enhancing its quality. The tank is equipped with a level gauge and pressure gauge for local display of liquid level and pressure. The interlayer insulation material is high-quality domestic pearl sand, with the following performance parameters of the pearl sand:

Section 3: Inspection, Testing, and Acceptance

1Inspect the inner cylinder material, and it can be put into use only after passing the inspection.

2All welds are subject toGB150.1～150.4-2011Inspection of standards and drawings is conducted; upon passing the inspectionA、BWeld-like seam100%Gamma-ray inspectionA、B、C、DWeld-like seam100Percent permeability testing with a test report issued

3After the cylinder assembly is completed, proceed to...GB150.1～150.4-2011Inspection of geometric dimensions, pipe end orientations, and shape deviations is conducted according to standards and drawings.

4After inspection and approval, conduct a pneumatic test and issue a pressure test report. Upon passing the pneumatic test, evacuate the system. Once the vacuum level meets the requirements, perform a helium leak test.

5After interlayer leak test passes, fill with pearl sand and then vacuum, achieving a vacuum degree ofGB/T18442-2011Standard requirements for the sealed vacuum degree.

60-cubic-meter Liquefied Natural Gas (LNG) storage tank approval procedures, 60-cubic-meter LNG storage tank, complete accident status analysis and prediction for the monitoring area based on monitoring data, operational control over process safety and emergency response, implement disaster relief plans; the level gauge should be repairable or replaceable under tank operation conditions; density variations must be considered during selection; a densimeter may need to be added if necessary, monitor the liquefied stratification inside the tank to prevent "upset" occurrences.

60-cubic-meter Liquefied Natural Gas (LNG) Storage Tank Approval Procedures, 60-cubic-meter LNG Storage Tank, Storage of LNG ① Determination of Storage Tank Volume: The total tank volume is typically determined based on the average daily gas consumption during the 3-7 peak days of the month, and should also consider factors such as the number of long-term gas supply sources, maintenance schedules, transportation cycles, and fluctuations in customer gas usage. Industrial gas consumption should be determined based on the nature of the gas-consuming equipment and specific production requirements.

60-cubic-meter Liquefied Natural Gas (LNG) tank, how many tons for a 60-cubic-meter LNG tank, 2) how many tons for a 60-cubic-meter LNG tank with slanted holes, application procedures for a 60-cubic-meter LNG tank, when storing low-temperature liquids, the filling rate must not exceed 0.95, and overfilling is strictly prohibited.

Application procedures for 60-cubic-meter LNG storage tanks, 60-cubic-meter LNG storage tanks, and jacketed vacuum powder-insulated pressure vessels for storing and supplying low-temperature liquefied gases (such as liquid nitrogen, liquid oxygen, liquid argon, liquid carbon dioxide, LNG, etc.) may all experience low-temperature frostbite incidents.

Pressure increase requires immediate closure of the lower inlet valve for the 20 cubic LNG storage tank. The vacuum degree of the 20 cubic LNG storage tank is good. Insulating materials should not cause corrosion to the pipelines and equipment.

60-cubic-meter LNG storage tank with what size vaporizer, approval procedures for a 60-cubic-meter liquefied natural gas storage tank, the nationwide promotion and application of LNG, and how to effectively manage the safety and technical aspects of LNG have become a new issue. (3) Cautionary Notes: a) During the operation of the LNG storage tank, it is mandatory to ensure the liquid level is ≥15%.
