This product is a horizontal fixed vacuum powder insulation low-temperature storage tank, featuring a double-layer cylindrical structure. The inner container is used for storing low-temperature liquid natural gas, while the outer shell forms and protects the vacuum insulation space. The interlayer is filled with mica sand and evacuated to create an effective insulation system. The design of the outer shell and support system can withstand the related external forces during manufacturing, transportation, installation, and use. The bottom of the tank is equipped with a complete set of valves, instruments, and safety devices for operation.
Safety:
One, stainless steel sheets are purchased from Taiyuan Iron and Steel Plant, which is the leading manufacturer of stainless steel sheets in China, ensuring quality. The tubing is sourced from Anhui Tianda Steel Tube, the top supplier of domestic stainless steel seamless tubes.
Material specifications are all in accordance withGB150-2011Re-inspection of "Pressure Vessel," cutting is performed using a CNC plasma cutting machine, with strict control over the geometric dimensions of the cylinder sections.
Section 3: Both longitudinal and circumferential seams are welded using submerged arc welding, resulting in good appearance and shape, with the inner lining also being processed.100%XRay inspection.
Vacuum Degree:
One, the inner and outer surfaces of the stainless steel liner are degreased and pickled, while the carbon steel shell's inner and outer surfaces are sandblasted for rust removal. This ensures the paint's adhesion, extends the paint's corrosion resistance lifespan, enhances the stainless steel plate's corrosion resistance, and reduces the venting of the sandwich, thereby guaranteeing the vacuum's longevity.
Prior to sand loading, the pearl sand undergoes a unique dehydration pretreatment, and the sandwich layer is heated and purged with nitrogen, significantly reducing the gas emission source.
Three, the process of using vacuum filling and positive pressure compaction for sand ensures the uniformity of the sandwiched pearlescent sand. The vibration rod compaction technique maximizes the filling amount of the pearlescent sand, thereby ensuring the insulation effect of the sandwich layer.
Four: Utilizing a unique vacuum extraction process, significantly reduces the time required to evacuate the inner tank and sandwich layers, ensuring the vacuum level within the sandwich exceeds national standards. Guarantees the vacuum level of the storage tank is3～5No reprocessing required within the year.
Appearance:
One. The bending of pipes is carried out on CNC bending machines, ensuring strict geometric dimensions. By not using elbow joints, it significantly reduces pipeline resistance and enhances the aesthetics of the outer piping system.
The paint used is from Jotun, a world-renowned brand, with two coats of primer and two coats of topcoat, ensuring the longevity of the paint and the quality of the equipment's appearance.
LiquefiedNatural Gas Storage TankA professional product for storing liquefied natural gas, a special equipment, a type III pressure vessel, made of 06Ni9DR material.

Common structures of LNG storage tanks include: vertical LNG tanks, horizontal LNG tanks, vertical mother-child tanks, and atmospheric pressure storage tanks.
Vertical LNG Storage Tank
Volumetric options include 50, 100, 150, and 200 cubic units.
Horizontal LNG Storage Tank
Volume options include 60 cubic and 100 cubic.
Vertical mother and son tanks
A mother tank refers to an inner tank composed of multiple sub-tanks connected in parallel to meet large capacity storage requirements. Multiple sub-tanks are assembled side by side within a large outer tank. The number of sub-tanks ranges from 3 to 7, generally not exceeding 12. The volume of a single sub-tank should not be too large, typically between 100 to 150 cubic meters, with the maximum reaching 250 cubic meters. Common sizes include 1000 cubic meters, 1750 cubic meters, and 2000 cubic meters.
Atmospheric Storage Tanks:
We offer large and medium-sized atmospheric LNG storage tanks, as well as extra-large atmospheric LNG storage tanks.
