1060 aluminum shapes API 650 stainless steel storage tanks
Design of a Double-wall TankThe outer bottom, shell, and roof of a double-wall tank shall enclose an insulating space around the bottom, shell, and roof or insulation deck of the inner tank that contains the stored liquid. The annular space shall be maintained at a low positive pressure, which necessitates that the enclosure be vapor-tight. The Purchaser shall specify the design metal temperature and pressure of the inner tank and may specify the design temperature and pressure of the outer tank API 650 stainless steel storage tanks. The Purchaser shall state the specific gravity of the content to be stored, roof live loads, wind load, earthquake load where applicable, and corrosion allowance, if any.
For API 650 tanks Projection from outside of tank shell to extreme face of flange - plus or minus 5 mm. API 650 stainless steel storage tanks Elevation or radial location - plus or minus 6 mm. API 650 tanks Flange tilt in any plane, measured on the diameter across the gasket surface - plus or minus degree but not exceeding 5 mm. Flange bolt hole orientation - plus or minus 2 mm.
Our client purchase more than 900 tons pipe API 650 stainless steel storage tanks from India. And we do the inspection for each one pipe before shipment.During the inspection, the inspector saw that the surface of the square pipe kept the original color of the stainless steel, no fracture, no depression and other quality defects was found.
}Natural ventilation loss: the main cause of natural ventilation loss is that the API 650 stainless steel storage tanks is not tightly sealed. This is usually due to corrosion perforation on the top of the oil tank, or there is a height difference between the two orifices. The air tightness of the mixture in the API 650 stainless steel storage tanks is higher than that of the air, which causes the mixture gas in the tank to be discharged into the atmosphere from the lower hole, and the external air flows into the tank from the high hole, resulting in natural ventilation loss.
