API Std 650 welded storage tanks anchorage forces
According to API standard 650, the stairs used for API 650 petroleum storage tanks or thermal insulation tanks should be double longitudinal beams supported by a minimum of ribs. If the gap between the API Std 650 welded storage tanks tank shell and the stringer of the API 650 petroleum storage tank exceeds 200mm, handrails should be provided on both sides of the stairs. Unless otherwise specified, according to API Std 650 welded storage tanks ASTM A123, the following accessories shall be hot-dip galvanized. The damaged zinc coating should be repaired with zinc alloy.
Strictly control the welding groove forming of API Std 650 welded storage tanks: in order to ensure the geometric dimension of assembly and good welding of welding seam, before hoisting and laying, the edge of all metal vertical storage tank plate shall be polished by grinder, and the flatness of plate shall be ensured according to the design requirements. Strictly control the size of API Std 650 welded storage tanks weld assembly: measures must be taken to strictly control the assembly size of metal vertical tank bottom plate during assembly.
Heat-affected zone impact specimens shall be taken across the weld and as near the surface of the material as is practicable. The API Std 650 welded storage tanks material specimens shall be of sufficient length to locate the notch in the heat-affected zone after etching. The notch shall be cut approximately normal to the material surface to include as much heat-affected zone material as possible in the resulting fracture. Impact test specimens shall be cooled to the temperature stated in Q.22.
