API 650 mechanically-anchored steel tanks restrictions on stiffening rings

In the petrochemical industry and other industries, large vertical API 650 mechanically-anchored steel tanks are often used to store various production raw materials. Usually, the medium with high melting point and easy to crystallize at room temperature can be exported and used after heating, which involves the heating of large vertical storage tanks. The heating system is an auxiliary facility for heating of large vertical storage tank. It is often necessary to design external heating coil or internal heating coil system.Soil Structure Interaction: Soil structure interaction per API 650, Section E.6.1.6 may be used for OLE design providing the damping ratio does not exceed 10 %.
Allowable Stresses
Design allowable stresses shall be per API 620 large welded steel storage tank, Section Q.3.3, including the 33 % increase permitted for earthquake loads.
Self-anchored Inner Tank
The anchorage ratio for a self-anchored inner tank, J, shall not exceed 1.0 for the OLE design combination to limit uplift and stresses in the annular plate and corner weld.
Foundation Stability
The overturning ratio defined in API 650, Section E.6.2.3, Equation (E.6.2.3-1) shall be equal to or greater than 3.0 for the defined OLE event.Welded steel API 650 mechanically-anchored steel tanks storage tanks that are designed, manufactured and installed on the ground are classified according to the API standard system. The three API standards API 650 mechanically-anchored steel tanks all adopt on-site production and installation of storage tanks.Aspire to technological innovation and pursue first-class quality steel API 650 mechanically-anchored steel tanks products.Take independent innovation as an important support for the sustainable development of iron and steel industry, strengthen the main position of technological innovation, accelerate the original innovation, integrated innovation, introduction, digestion, absorption and re innovation, improve the technological innovation system, and cultivate the core technology and brand products of independent intellectual property rights.We are professional API 650 mechanically-anchored steel tanks carbon steel plates supplier with good reputation, and have participated many significant projects that finished with carbon steel materials in the world.
