A106 grade B pipe API Std 650 flat-bottom tanks

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for API Std 650 flat-bottom tanks various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several API Std 650 flat-bottom tanks after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

The main advantages of the external floating roof API Std 650 flat-bottom tanks are large storage capacity, suitable for storing more than 10000 cubic meters of crude oil. Compared with the internal floating roof API Std 650 flat-bottom tanks, the production of external floating roof API Std 650 flat-bottom tanks is simple and the steel consumption is less. However, the central drainage system of external floating roof API Std 650 flat-bottom tanks should be installed on the outer floating roof to ensure that the accumulated water can be discharged smoothly in rainy and snowy days, and avoid sinking accident.

Insulation Load
For API 620 tanks designed and constructed with an outer tank containing loose fill insulation in the annular space between the tanks, the insulation weight shall be divided equally to the inner and outer tank wall for seismic lateral loads unless a more rigorous analysis is performed to determine the distribution. The insulation within the annular space shall not be used to calculate resistance to overturning. Insulation on the API Std 650 flat-bottom tanks roof or suspended deck shall be applied to the tank supporting the load at the point or center of gravity of attachment and may be used to resist overturning.
