API standard 650 cylindrical liquid-storage tank hatches

API 650 is an American standard for welding flat bottom vertical storage tanks. This API standard 650 cylindrical liquid-storage tank standard specifies requirements for the design, manufacturing, welding, inspection and installation of storage tanks. API 650 is widely used in storage tanks designed to withstand low internal pressures and used to store typical products such as API standard 650 cylindrical liquid-storage tank crude oil, gasoline, chemicals and water. BBN has extensive experience in API 650 tanks, from +/- 500 cubic meters of tanks produced in the factory to +/- 15000 cubic meters of tanks produced on site.

Suggested Practice Regarding Installation of Low-pressure Storage Tanks
Access: All openings and accessories for tanks API standard 650 cylindrical liquid-storage tank constructed according to this standard shall be installed so that any periodic inspections required can be readily made.
Corrosion: When a tank bottom rests directly on the ground, a survey shall be made to establish the need for cathodic protection.
Drainage: All tanks in which water might accumulate under the hydrocarbon contents shall be provided with adequate drains that are suitably protected from freezing.

As we know, the vertical metal tank, API standard 650 cylindrical liquid-storage tank is welded by many components, and the welding quality of each component determines the later use effect of the API standard 650 cylindrical liquid-storage tank. Professional API standard 650 cylindrical liquid-storage tank manufacturers should have a set of professional skills in the welding process of API standard 650 cylindrical liquid-storage tank. Key points for weld inspection of vertical metal tank, API standard 650 cylindrical liquid-storage tank:
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.
