Stainless steel tank features


Release time:

2019-06-24

Features of stainless steel storage tanks (LNG storage tank, liquid oxygen storage tank, liquid nitrogen storage tank, liquid argon storage tank, liquid carbon dioxide storage tank): 1. stainless steel is purchased from Taiyuan Iron and Steel Plant. Taiyuan iron and steel plant is the domestic production of stainless steel plate leading enterprises, quality assurance. The pipe adopts Anhui Tiangda steel pipe, the first supplier of stainless steel smooth pipe in China. 2. materials are re-inspected in accordance with the GB150-2011 "Pressure Vessel". CNC plasma cutting machine is used for blanking, and the geometric size of the tube section is strictly controlled. Submerged arc welding shall be used for longitudinal and circumferential welding of the 3., with good appearance and 100 of the inner container.

1. stainless steel are purchased from Taiyuan Iron and Steel Plant. Taiyuan iron and steel plant is the domestic production of stainless steel plate leading enterprises, quality assurance. The pipe adopts Anhui Tiangda steel pipe, the first supplier of stainless steel smooth pipe in China.

2. materials are re-inspected in accordance with the GB150-2011 "Pressure Vessel". CNC plasma cutting machine is used for blanking, and the geometric size of the tube section is strictly controlled.

Submerged arc welding shall be used for longitudinal and circumferential welding of the 3., with good appearance and 100%X-ray inspection for the inner container.

4. pipe bending is carried out on the CNC pipe bending machine, which strictly ensures the geometric size of the pipe bending. Without the use of elbow docking, greatly reducing the pipeline resistance, but also improve the aesthetics of the external pipeline system.

The inner and outer surfaces of the 5. stainless steel liner are degreased and pickled and passivated, and the inner and outer surfaces of the carbon steel shell are sandblasted to ensure the adhesion of the paint, prolong the corrosion resistance of the paint, improve the corrosion resistance of the stainless steel plate, reduce the amount of outgassing of the interlayer, and ensure the life of the vacuum.

Pearlescent sand is dewatered and pre-treated before 6. sand loading, and the interlayer is heated and replaced with nitrogen, which greatly reduces the source of outgassing.

The process of negative pressure filling and positive pressure compaction is used for 7. sand loading to ensure the uniformity of the laminated pearlescent sand. The vibrating rod compaction process is adopted to increase the filling amount of pearlescent sand to the limit and ensure the cold preservation effect of the interlayer.

The 8. uses a unique vacuum pumping process, which greatly shortens the evacuation time of the liner and the interlayer, and ensures that the vacuum degree of the interlayer is better than the requirements of the national standard. Ensure that the vacuum degree of the storage tank does not need to be reprocessed within 3 to 5 years.

The 9. paint adopts the world famous brand Jotun paint, spraying primer twice and topcoat twice, ensuring the service life of the paint and the appearance quality of the equipment.

10. each kind of low-temperature oxygen, nitrogen and argon storage tank and LNG storage tank with large sales volume in the market have a certain amount of finished products and semi-finished products in stock, the user's requirements for the construction period can be guaranteed to the greatest extent.
