API standard 650 austenitic stainless steel storage tanks roof manufacturer
For API 650 tanks Projection from outside of tank shell to extreme face of flange - plus or minus 5 mm. API standard 650 austenitic 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.
Butt-welded joints used to fabricate large steel storage tank fittings shall be completely radiographed. Lines carrying liquid shall be hydrostatically or pneumatically pressurized at a minimum pressure of 35 lbf/in.2 and API standard 650 austenitic stainless steel storage tanks butt welded joints shall be simultaneously visually examined (hydrostatic) or solution film tested (pneumatic) for tightness. If manufactured pipe has been hydrostatically tested previously to ASTM requirements, then only circumferential welds need to be examined.
Volatilization is the characteristic of oil. Under normal temperature and pressure, as long as the oil is in contact with air, the surface will volatilize. Through scientific analysis and summary, the causes of oil volatilization loss in API standard 650 austenitic stainless steel storage tanks are: natural ventilation loss, static storage loss, dynamic liquid level loss. In the use of API standard 650 austenitic stainless steel storage tanks, static storage loss and dynamic liquid level loss are common losses.
