40ft diameter API Std 650 cylindrical liquid-storage tank

Welding of Large Steel storage tank Primary Components
a)Longitudinal and circumferential shell joints and joints that connect the API Std 650 cylindrical liquid-storage tank annular bottom plates together.
b)Joints that connect sections of compression rings and sections of shell stiffeners together. Backup bars may be used for these joints with complete penetration and complete fusion detail.
c)Joints around the periphery of a shell insert plate.
d)Joints that connect the shell to the bottom, unless a method of leak checking is used (see Q.8.2.1).

Supply covers for API Std 650 cylindrical liquid-storage tank connections specified with the service covers remaining in place following tests. For API 650 tank connections not specified to be supplied with service covers, the test covers may be removed after testing.

In 2015, we offered 230 tons 309S and 310S stainless steel API Std 650 cylindrical liquid-storage tank plate to Vietnam fabrication company. The products are used in fabricating machine for this company. Then the customer sell the machine to south America and European market. This Vietnam company purchase more than 100 ton stainless steel from us every month.

Generally, the snow load in the API Std 650 cylindrical liquid-storage tank construction area should be considered before the design and construction of the tank. The snow load in the API Std 650 cylindrical liquid-storage tank construction area has an impact on the tank roof design and operation, especially in the area with large snow load, the roof load of large storage tank with large diameter increases. Anti freezing, heat preservation and waterproof measures shall be taken for the additional facilities of storage tanks, such as pumps, breathing valves, flame arresters, detection instruments and thermal insulation layers.

When providing technical services on site, the after-sales personnel shall strictly abide by the safety rules and regulations of the construction site, consciously take safety protection measures (such as wearing safety helmet when entering the construction site), accept the supervision and management of the site; without permission on the construction site, they shall not dismantle, smear or damage any goods; the commissioning of contract goods shall be carried out under the supervision of the site supervisor If necessary, it shall be approved by the site supervisor or the person in charge of the project department.
