API standard 650 open top welded storage tanks tack weld

The finned tube heating device for high temperature heat transfer oil for large API standard 650 open top welded storage tanks has the advantages of convenient inspection and maintenance. The high-efficiency fin heating coil assembly is composed of spirally arranged finned coils. The fins are mainly arranged in the straight pipe section, and the whole assembly is supported by several angle steel supports. The high-efficiency fin heating coil component can enter and exit from the manhole of the API standard 650 open top welded storage tanks, which is convenient for maintenance and repair.

Storage tanks API standard 650 open top welded storage tanks designed in accordance with the rules and guidelines of API 650 are called API 650 storage tanks. API 650 is a control rule for welded storage tanks that work normally in the normal pressure range.

The company's logistics team adheres to the development concept of “gathering advantages, providing superior services, creating value, and leading the market”, and tightly focuses on the strategic positioning of “developing large-scale steel logistics and building large-scale steel supermarkets”. Facing the whole country and integrating into the world to build an "one center, one network" international circulation system. Through the development of 5-10 years, it is expected to form a modern steel industry with annual operating income exceeding 2.5 billion yuan.

In this project, an area of steel storage oil 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.
