API 650 mechanically-anchored steel tanks shaping of shell plates

API 650 petroleum storage tank has the advantages of high safety: the API 650 mechanically-anchored steel tanksinner floating plate floats on the liquid surface, so that the liquid phase has no evaporation space, which can reduce the evaporation loss by 85% to 90%. At the same time, the API 650 petroleum storage tank blocks the air and liquid storage through the floating disk, which reduces air pollution and reduces the degree of fire risk.

Atmospheric API 650 mechanically-anchored steel tanks inspection includes annual inspection and comprehensive inspection. Annual inspection is an inspection during operation to ensure the safety of atmospheric storage tanks during the overhaul period, at least once a year. Comprehensive inspection is a more comprehensive inspection of atmospheric storage tanks according to a certain inspection cycle. The inspection content of metal atmospheric API 650 mechanically-anchored steel tanks includes the safety management of the storage tank, the inspection of the tank body and its operating conditions, etc.

The API 650 mechanically-anchored steel tanks stiffener ring and backing strip (if used) are primary components, and they shall comply with the requirements of API 620 storage steel tank Q.2.1. The stiffener rings may be fabricated from plate using an intermittent weld on alternating sides between the web and the flange.
Except for aluminum or stainless steel tanks, all fillet welds shall consist of a minimum of two passes. The ends of the fillet welds shall be 2 in. from the rat hole (see Figure Q-1), and these welds shall be deposited by starting 2 in. from the rat hole and welding away from the rat hole. An acceptable alternative to the detail that includes stopping fillet welds 2 in. short of the rat hole would be to weld continuously through the rat hole from one side of the stiffener to the opposite side. All craters in fillet welds shall be repaired by back welding.

Our company's technical department is the core department of the whole company. There are a group of very professional technical personnel. They provide some architectural drawings according to the ideas of customers, and they are responsible for how to select the right materials. Including the evaluation of steel products such as multi steel plate, API 650 mechanically-anchored steel tanks and steel pipe, grasp the whole production process, and strictly follow the production standards and customer quality requirements.

The predecessor of Ningbo port is Ningbo Port Authority. Ningbo port consists of Beilun port, Zhenhai port, Ningbo port, Daxie port and Chuanshan port. It is a multi-functional and comprehensive modern deep-water port integrating inland river port, estuary port and seaport.
