double-deck-type floating roof API 650 mechanically-anchored steel tanks

In line with the service concept of "honesty first, customer first" and the service tenet of "all for customer satisfaction", the company adopts the acceptance and response mode of combining manual and automatic, and accepts the diversified service demands of customer business consultation, complaint declaration, business acceptance, etc through telephone, fax, e-mail, visit, letter, etc,API 650 mechanically-anchored steel tanks. Pressure-relieving DevicesTanks shall be protected by automatic pressure-relieving devices that will prevent the pressure at the top of the tank from rising more than 10% above the maximum positive gauge pressure except as provided in API 620 standard 9.2.2.Where an additional hazard can be created by the exposure of the tank to accidental fire or another unexpected source of heat external to the tank, supplemental pressure-relieving devices shall be installed. These devices shall be capable of preventing the pressure from rising more than 20% above the maximum positive gauge pressure. A single pressure-relieving valve may be used if it satisfies the requirements of this paragraph and 9.2.1.In Appendix E to API 650 oil storage tank, the maximum values of inertia force, pulse pressure and convection pressure are superimposed, and tend to be conservative.In GB50341, only pulse pressure is calculated for API 650 mechanically-anchored steel tanks tanks below 5000 m.The API 650 mechanically-anchored steel tanks company has established the corporate values of being proud of innovation and winning, and successfully realized the management of corporate culture. In BBN, leaders are not controllers and supervisors, but earnest API 650 mechanically-anchored steel tanks teachers, coaches and enthusiastic friends, so that employees can have more democracy, more autonomy, independence and creativity, and the belief of winning.Deformation of the welding seam of the API 650 mechanically-anchored steel tanks is a common quality problem during the actual use of the API 650 mechanically-anchored steel 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 650 mechanically-anchored steel 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.
