API Std 650 ground supported liquid storage tanks designed to operate under external pressure conditions

Inspection of Butt-welds in Piping
Butt-welds in piping and in API Std 650 ground supported liquid storage tanks pipe fittings within the limitations of 1.3.2 (including the annular space of double- wall tanks) shall be inspected in conformance with API 620 oil tank standard Q.7.7.2 through Q.7.7.6. Longitudinal welded joints in piping that contains liquid shall be completely radiographed except for manufactured pipe welded without filler metal, 12 in. or less in diameter, which is tested hydrostatically or by eddy current to ASTM requirements.

The application of API 650 is as stated by the American Petroleum Institute: The production and installation of our ground welded steel API Std 650 ground supported liquid storage tanks storage tanks are generally used in industry; under normal circumstances, the storage tanks installed on the industrial site in the United States are in accordance with API 650, API 620 and API 12d Standards are established.

We supply 5800 tons A53 Gr B ERW pipes to Qatar for Qatar Integrated Railway Project - Green Line. This is the first Metro Line in Qatar, and it is located in Doha. We got the order by tender, launched by the Qatar Railways Company for designing, construction and completion of Green Line Project. Before putting order, a delegation from the API Std 650 ground supported liquid storage tanks project side visited us and several other famous steel pipe mills in China for 15 days. Finally, we were chosen and finished the task exceeding their expectations.

Usually, the wind load in the API Std 650 ground supported liquid storage tanks construction area should be considered before the tank design and construction. The wind load in the API Std 650 ground supported liquid storage tanks construction area has an impact on the stability and economy of the API Std 650 ground supported liquid storage tanks. In the area with large wind load, it is safe to design the tank as "squat". When calculating the wind force, the influence of the thickness of the insulation layer of the API Std 650 ground supported liquid storage tanks, the shape of the ladder, the platform, the pipeline and the top cover must be considered.

Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.
