API 650 flexible liquid storage tanks tank shell

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

The welded steel API 650 storage tank API 650 flexible liquid storage tanks is designed, manufactured and installed on the surface according to the API standard system classification. API 650, API620 and API 12D belong to the API standards for professional construction.

As we know, the vertical metal tank, API 650 flexible liquid storage tanks is welded by many components, and the welding quality of each component determines the later use effect of the API 650 flexible liquid storage tanks. Professional API 650 flexible liquid storage tanks manufacturers should have a set of professional skills in the welding process of API 650 flexible liquid storage tanks. Key points for weld inspection of vertical metal tank, API 650 flexible liquid storage tanks:
1. It is strictly forbidden to paint the welds before passing the inspection.
2. Visual inspection shall be carried out for welds.
3. NDT shall be carried out on the weld.
