A841 grade A class 1 plates API standard 650 carbon and low-alloy steel tanks

Welders participating in the construction of API standard 650 carbon and low-alloy steel tanks must pass the examination and perform welding within the validity period of the qualified items. Special operators such as on-site maintenance electricians, cranes, and shelf workers must hold job certificates. All oil pipelines need to use arc welding for bottoming and electric welding to ensure the welding quality. Oil tanks and process pipelines must be tested for non-destructive flaws in accordance with the flaw detection ratios and methods required by the design and acceptance specifications. The flaw detectors must be certified.Allowable Design Stresses
The maximum allowable design stresses for the API standard 650 carbon and low-alloy steel tanks materials outlined in Q.2.1 shall be in accordance with Table Q-3.The values for the allowable design tensile stress given in Table Q-3 for materials other than bolting steel are the lesser of (a) 331/3% of the specified minimum ultimate tensile strength for the material or (b) 662/3% of the specified minimum yield strength, but they are 75% of the specified minimum yield strength for the stainless steel, nickel alloy, and aluminum materials. Allowable test stresses are based on the limitation of API 620 oil tank storage standard Q.8.1.3.API 650 is used to store products such as crude oil, gasoline, chemicals, and produced water. BBN has extensive experience in API standard 650 carbon and low-alloy steel tanks API 650 tanks with diameters between 8'-300', which are suitable for refineries, terminals, pipeline facilities and other projects.Group consciousness is an important psychological factor for the formation of enterprise internal cohesion.
