API 650 liquid storage tanks materials

The specifications used in the design of large oil tanks, API 650 liquid storage tanks mainly include American Petroleum Institute Standard API 650, Japanese Industrial Standard JIS B8501, British Industrial Standard BS2654 and Chinese National Standard GB50341 from a global perspective. The formulas used in each specification are based on the hoop stress in the membrane theory. Each specification is based on the performance characteristics of materials and the construction technology level of their respective countries to determine the allowable stresses and weld coefficients. Therefore, the calculation results of tank wall thickness of API 650 liquid storage tanks with the same volume are sometimes quite different according to different specifications.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 650 liquid storage tanks 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.This API 650 tank standard does not present orstablish a fixed series of allowable tank sizes: instead, it s intended to permit the purchaser to select whatever size API 650 liquid storage tanks tank may best meet his needs.Team concept: respect, communication, coordination and symbiosisBusiness philosophy: leading by strategy, driving by innovation, creating valueManagement concept: goal oriented, efficient operation, stimulation of vitality and continuous improvementQuality concept: standard guidance, control process, craftsman spirit, leading serviceTalent concept: lifelong learning, give full scope to the talents, the sea refuses no riverInnovation concept: innovation is the first driving force for the company's high-quality developmentCustomer concept: taking customers as the center is the foundation of the company's survival and developmentWe have a good inventory system because of which the alloy steel plates and structural steel sheets are supplied and delivered to our customers on time. Our alloy steel plate is significantly affordable than austenitic API 650 liquid storage tanks stainless steel which helps to reduce maintenance and full life costs – as well as improved safety over standard boilerplate.
