Large volume asphalt storage tank adopts integral segmented welding forming process to ensure overall structural firmness and dimensional accuracy.

High-quality thick steel plates are selected as raw materials, with strict raw material inspection to guarantee bearing capacity and anti-deformation performance.

Advanced automatic welding technology is applied for tank body splicing, forming dense welds with strong tightness and pressure resistance.

Precise bending and rolling processing makes the tank wall radian uniform, effectively avoiding local stress concentration.

Reinforced rib structure is added inside and outside the tank body to enhance overall stability suitable for large-capacity material storage.

Multi-layer thermal insulation laying construction is carried out in standardized procedures to ensure uniform and stable heat preservation effect.

Internal anti-sticking and anti-corrosion treatment is implemented to prevent asphalt adhesion and slow down inner wall corrosion wear.

Professional heating pipeline layout is completed in fixed positions to realize even heat distribution inside the large tank.

Strict water pressure sealing test and leakage detection are conducted after assembly to eliminate hidden leakage troubles.

The whole manufacturing process follows industrial standards, featuring stable quality, long service life and good adaptability for bulk asphalt storage stations.
