A841 grade B plates API 650 austenitic stainless steel storage tanks

API 650 austenitic stainless steel storage tanks, Oil tank is a large-scale storage equipment used to store oil materials. Usually, the service life of API 650 austenitic stainless steel storage tanks is related to the actual working conditions. The design service life of most oil tanks is 20 years, and some of them are 10-15 years. Generally, none of them is less than 10 years. However, the design service life of API 650 austenitic stainless steel storage tanks is on the one hand, which is an ideal state, but there are many objective factors in the actual process, it is impossible to achieve the designed service life. How to effectively increase the service life of API 650 austenitic stainless steel storage tanks?

Ultrasonic Examination of Butt-welds in Plates
Butt-welds in all tank wall courses subjected to a maximum actual operating membrane tensile stress, perpendicular to the welded joint, greater than 0.1 times the specified minimum tensile strength of the API 650 austenitic stainless steel storage tanks plate material shall be completely examined.
Butt-welds in API 620 oil tank wall courses subjected to maximum actual operating membrane tensile stress, perpendicular to the welded joint, less than or equal to 0.1 times the specified minimum tensile strength of plate material shall be spot examined in accordance with Figure Q-2.
