API Std 650 horizontal tank side entry mixers

Welding of Large Steel storage tank Primary Components
a)Longitudinal and circumferential shell joints and joints that connect the API Std 650 horizontal 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).

API 650 is constructed from carbon steel, austenitic duplex stainless steel, and API Std 650 horizontal tank aluminium A Welding Certification is stipulated by American Society of Mechanical Engineers (ASME), Section 10. There is a required inspection, no third party. The inspection cost is the cost of the NDE.

During heavy rain, closely observe the change of the water level in the storage area of the API Std 650 horizontal tank. If the water level rises to the dangerous range, drain the water immediately. There are more thunderstorms in heavy rain, and lightning protection devices should be installed in the API Std 650 horizontal tank area to avoid lightning accidents. Observe the groundwater level of the API Std 650 horizontal tank area at any time, clean and dredge the drainage ditch in time to ensure unobstructed drainage, and prevent the bottom of the API Std 650 horizontal tank from leaking and rusting due to untimely drainage.
