Large API standard 650 unanchored flat-bottom tank
API 650 is the standard for welded tanks for oil storage. It specifies the design, manufacturing, welding, inspection and installation requirements of oil tanks. API 650 API standard 650 unanchored flat-bottom tank is widely used in storage tanks with internal pressure less than or equal to 2.5 PSI, used to store products such as crude oil, gasoline, chemicals, and produced water. BBN has extensive experience in API standard 650 unanchored flat-bottom tank API 650 tanks with diameters between 8'-300', suitable for refineries, terminals, pipeline facilities and other customers.
The insert plate weld shall not cross any shell seams and shall be at least the greater of 10 times the shell thickness or 12 in. from any other weld in the API standard 650 unanchored flat-bottom tank shell including shell seams, shell-to-bottom weld or attachment welds. The butt weld around the periphery of the plate shall be examined over 100% of its length by both liquid penetrant method and radiographic method. The liquid penetrant examination is required on the root pass, on the back-gouged surface, and on the inside and outside finished weld surfaces. Additionally, the weld shall be vacuum box leak tested.
API standard 650 unanchored flat-bottom tank Nondestructive testing is a technical means to detect the weld defects of large vertical tank and judge whether the weld is qualified by using the characteristics of sound, light, magnetism and electricity without damaging the tested object. Common nondestructive testing methods: ultrasonic testing (UT), magnetic particle testing (MT), liquid penetrant testing (PT) and X-ray testing (RT).
