EN S355 plates API standard 650 welded tanks for oil storage
For API 650 tanks Projection from outside of tank shell to extreme face of flange - plus or minus 5 mm. API standard 650 welded tanks for oil storage Elevation or radial location - plus or minus 6 mm. API 650 tanks Flange tilt in any plane, measured on the diameter across the gasket surface - plus or minus degree but not exceeding 5 mm. Flange bolt hole orientation - plus or minus 2 mm.
In this project, an area of tank wall is constructed of ASTM A285, Grade C, steel plate that is 5/8-in. thick and has spot-radiographed, double-welded butt joints. The wall is subject to tension in a meridional direction and to compression in a latitudinal direction. The values of R1 and R2 at the point under consideration are 75 in. and 300 in. respectively. A corrosion allowance of 1/16 in. is required. The computed (meridional) tensile stress, stc, in the net thickness after deduction of the corrosion allowance is 6000 lbf/in.2. The problem in this example is to find the maximum allowable (latitudinal) compressive stress value for the given conditions, in conformance with the provisions of API 620 tank standard 5.5.4.5.
Corrosion of the API standard 650 welded tanks for oil storage body caused by external conditions such as high temperature, rain, humidity, or inadequate anti-corrosion measures of the oil storage tank itself, the water-bearing deposits in the oil storage tank caused corrosion and perforation of the inner surface of the oil storage tank bottom plate. Defects fatigue cracks caused by stress, with the accumulation of time, the compressive strength of the API standard 650 welded tanks for oil storage body decreases and corrosion cracks occur.
Keep in mind your mission and never forget your mission." At present, the BEBON steel leadership team unites the majority of cadres and employees to keep in mind their glorious missions, guided by Xi Jinping's ideology of socialism with Chinese characteristics in the new era, fully implementing the spirit of the 19th CPC National Congress, in-depth implementation of the requirements of the "three advances", pioneering spirit, and striving In order to lead high-quality development with innovation, build a new pattern of Anshan Iron and Steel's revitalization and development, strive to build the most internationally influential steel company, and make new contributions to the start of a new journey for BEBON Iron and Steel Group.
Tianjin warehouse mainly stores steel plates and steel pipes. The monthly replenishment is about 12000 tons. Our inventory cycle is short and flexible. Shanghai warehouse mainly stores API standard 650 welded tanks for oil storage ,steel plate and section steel. The average monthly purchase volume is about 15000 tons. The geographical location of the warehouse has greatly improved our performance in terms of transportation and delivery time.
Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
