Behavior of API standard 650 mechanically-anchored steel tanks

The API 650 is widely used for tanks designed to withstand low internal pressures, for the API standard 650 mechanically-anchored steel tanks storage of typical products such as crude oil, petrol, chemicals and water. We have extensive experience when it comes to API 650 tanks, varying from tanks built in the factory up to +/- 500m3, to tanks built on-location up to +/-15,000 m3.

The factors that affect the "small breathing" loss of API standard 650 mechanically-anchored steel tanks are: 1. Generally, the larger the storage tank is, the larger the total open area is, the larger the evaporation area is, and the greater the "small breathing" loss is; conversely, the smaller the storage tank is, the smaller the evaporation area is and the smaller the "small breathing" loss is. 2. It is related to the atmosphere. The lower the atmospheric pressure is, the greater the "small breathing" loss is; otherwise, the loss is reduced.

For all API 620 crude oil tank other materials, the impact test temperature shall be at least 30°F colder than the design metal temperature. Alternately, materials impact tested at the design metal temperature or lower with Charpy impact test energy value of 25 ft-lb (average), 20 ft-lb (minimum) are acceptable for design metal temperatures above –40°F. API standard 650 mechanically-anchored steel tanks materials with an energy value of 30 ft-lb (average), 25 ft-lb (minimum) are acceptable for design metal temperatures of –40°F or lower.

After comprehensive and professional training such as customer service, the customer service team has more strict discipline in the management of customer service team to ensure that customer service personnel respond to customers with a professional attitude. A process supervision system has been set up to let each customer supervise the process of the system with us

The company attaches great importance to logistics services, sets up our own transport truck fleet, improves customer response capacity through the improvement of logistics capacity, and further reduces costs. Customers ordering API standard 650 mechanically-anchored steel tanks steel from our company can not only enjoy the service of fast delivery, but also enjoy lower transportation costs. Fast, accurate, simple and efficient has always been our principle.
