API 650 petroleum storage tanks are classified according to their environment: Above-ground storage tank: refers to the bottom of the storage tank at the design elevation of API Std 650 closed top welded storage tanks and above; the bottom of the tank is below the design elevation of +0.00 but not exceeding.Service concept: first time to understand customer needs, first time to solve customer worriesVision: to be the leading steel materials supplier in the worldWorking principles: Keep promises; Spare no efforts; Be practical and innovative; Pursue excellenceTalent concept: build a team with a dream and complete a dream with a team!Family culture: we rely on the principles of equality, trust, appreciation and family love to form a harmonious and warm family!Deformation of the welding seam of the API Std 650 closed top welded storage tanks is a common quality problem during the actual use of the API Std 650 closed top welded storage tanks, which easily causes the tank body to leak and affects the safety of the oil storage tank. The welding seam deformation of the API Std 650 closed top welded storage tanks is mainly caused by the lack of reserved welding seam gap and irregular operation. The oil storage tank has not reserved the corresponding weld gap, resulting in deeper root removal during the front welding activity. The heat output of the weld will increase under the influence of a long time, and the deformation of the weld will gradually become serious.
