API Std 650 self-anchored storage tanks toughness procedure of plates

Allowable Design Stresses
The maximum allowable design stresses for the API Std 650 self-anchored storage 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 Std 650 self-anchored storage tanks API 650 tanks with diameters between 8'-300', which are suitable for refineries, terminals, pipeline facilities and other projects.

In 2013, one of our clients in Korea purchased 890 tons Q345B square tube from us for one building construction project. Our clients required no burr in the side of the tube, we finally produce the goods with great condition and +/-0.25mm tolerance for wall thickness, which is a very great tolerance with customers’ required size. Our square tube full available range is 2-16mm for wall thickness, and 40-500mm for width. In addition, our Q/C department will seriously control all of the process of every order.

Unqualified welding quality of API Std 650 self-anchored storage tanks is prone to hidden dangers such as oil tank steel plate cracks and leakage. To avoid this situation as much as possible, it needs to be avoided when the oil storage tank is manufactured. Scientific and reasonable measures are adopted to control the welding quality when welding the API Std 650 self-anchored storage tanks. How to reasonably control the welding process quality of oil storage tanks?
